Malfunctions and repairs of the VAZ-2109 starter retractor relay

Today we will look at an important topic for owners of the “nine” - malfunctions and repairs of the VAZ-2109 starter solenoid relay. As a rule, it is this device that is the reason that car drivers have to disassemble the entire starter to find out why the mechanism does not work. Sometimes this problem can be solved by itself if you charge the car battery well or carefully clean the contact connections, all of which can oxidize over time. In any case, the owner of a car from the domestic auto industry needs to be able to understand his own iron friend, since trouble can happen on the road when there is no service station nearby.

Troubleshooting and repair of VAZ 21099 starter

1.

Clean all starter parts.

2.

Check the condition of the stator winding. To do this, turn on the test lamp in the 220 V AC circuit and connect the wire to one of the terminals of the stator winding, and connect the other end of the circuit to the housing. If the lamp is on, it means the winding insulation is damaged. Replace winding or stator. Check the second winding in the same way (see note).

The stator windings can be checked with a megometer. Connect one contact to the terminal and the other to the stator housing. The winding resistance must be at least 10 kOhm. If it is less, replace the stator.

3.

Inspect the anchor. If the collector is dirty or has marks, scratches, etc., sand it with fine glass sandpaper. If the commutator is significantly rough or if there are mica protrusions between the plates, grind the commutator on a lathe and then sand it with fine glass sandpaper. The runout of the core relative to the shaft journals should not exceed 0.08 mm. If the runout is greater, replace the armature.

4.

If you find yellow deposits from the bearing on the armature shaft, remove it with fine sandpaper, otherwise it will cause the gear to jam on the shaft. If there are burrs or nicks on the surfaces of the journals and shaft splines, replace the armature.

The armature windings can be checked with a megometer. Connect one of its contacts to the commutator, the other to the armature core. The winding resistance must be at least 10 kOhm. If there is less resistance, replace the armature.

5.

Check the reliability of soldering of the armature winding leads to the commutator plates. Inspect the winding at the ends of the armature: the diameter of the winding should be less than the armature iron package. If the diameter is larger, replace the armature.

6.

Check the condition of the armature winding using a test lamp in a 220 V AC circuit. Connect the wires to the commutator plate and the armature core. If the lamp lights up, it means there is a short circuit in the armature winding or commutator plate to ground. In this case, the anchor must be replaced (see note).

9.

If drive parts are severely worn or damaged, replace the drive. If you find nicks on the leading part of the gear teeth, grind them with a fine-grained sanding wheel of small diameter.

11.

Inspect the bushing pressed into the clutch housing. If the bushing is worn or has burrs, pits, etc., replace the bushing.

Brushes worn to a height of less than 12 mm must be replaced.

13.

Check the movement of the brushes in the holders: the brushes should move easily, without jamming. Check that the brush holders are securely fastened: they must be securely fastened.

14.

Insulated brush holders must not be shorted to ground. Check this with a test lamp.

15.

Check the force of the springs pressing the brushes using a dynamometer. To do this, insert the armature into the cover on the drive side, install the housing and brush holder. Insert the brushes into the brush holders. At the moment the spring comes off the brush, the force should be in the range of 9.0–11.0 N (0.9–1.1 kgf).

16.

Check the resistance of the traction relay windings with an ohmmeter. The resistance of the pull-in winding should be in the range of 0.52–0.59 Ohm (red), and the holding winding – 0.725–0.795 Ohm (yellow) at an ambient temperature of +15 to +25 °C. The traction relay armature must move freely in the housing without jamming.

Simultaneously with checking the winding resistance, check whether the contact plate closes the contact bolts of the traction relay. If the ohmmeter shows “∞”, then either there is a break in the winding or the plate does not close the contact bolts. In both cases, the traction relay must be replaced.

1 – contact plate 2 – rectangular heads of slip rings

17.

Inspect the contact bolts. Clean the burnt bolt heads with fine sandpaper. If the heads are severely burned out, you can rotate the bolts 180° so that they are pressed against the contact plate with the unburnt side. If the surface of the contact plate is heavily worn, it can be turned with the other side towards the contact bolts.

Repair of a collapsible solenoid relay

The manufacturer equips starters with a non-separable or collapsible retractor device. If a non-separable relay breaks down, it must be replaced, but a dismountable relay can be repaired. The described method allows you to check the solenoid relay of all VAZ models: 2101, 2102, 2103, 2104, 2105, 2106, 2107, 2108, 2109, 21099, 2110, 2111, 2112, 2113, 2114, Niva, Lada Priora, Kalina, Granta, Vesta and most foreign cars. Disassembly and repair of the relay is carried out in the following order:

1. Unscrew the nuts securing the housing cover.
2. If necessary, the ends of the windings are additionally soldered.
3. After removing the cover, inspect the power contacts:

• If they burn, the damaged part is cleaned with sandpaper;
• When worn out, replace.

1. The device is assembled in the reverse order and tested for functionality.
2. The repaired relay is installed back on the starter.

The starter does not turn over, what should I do?

In the life of owners of the VAZ-2114, and other cars close to this line (see above), sometimes such an unpleasant moment arises when you need to go somewhere, but it is not possible to start the power plant due to the fact that the starter does not turn the flywheel engine.

That is, when you turn the ignition key to the “start” position, nothing happens.

And if in the summer you can calmly look for the cause of the malfunction, then in the winter, in severe frost, you won’t spend much time searching for the malfunction. And in order to quickly fix a breakdown, you need to know where to look for it.

How to quickly start your car in cold weather, see below.

How to repair a car starter with your own hands?

Having noticed the first signs of a malfunction, do not delay repairing the starter. Delaying checking and restoring will lead to the fact that at one point the engine simply will not start. We’ll show you in the video and tell you how to check the solenoid relay, replace the brushes and starter bushings in order to fix the breakdowns with your own hands and correctly assemble the car starter.

Where is the starter relay located on the VAZ 21099 Telegraph

Starter activation relay - many will now think that we are talking about a retractor relay, in fact this is not so, in total the starter has two relays, one that turns it on and the second that extends the bendix and pushes its gear onto the crankshaft pulley. The second is the same retractor relay , if the first one fails, this happens rarely, mainly due to overloads on it or because of faulty wiring, you will not be able to start the starter and therefore the car will not start; if the second one fails, the situation will be a little different, but the car may also not start and the clicking will occur when you turn the key, but this can be said even less, but if this relay fails completely and does not return the bendix to its reverse position, then the following will happen: when you turn the key, the starter will start turn the engine of the car and eventually it will start, but when you return the key after the engine has started in the reverse position, the bendix at the starter will not come back. The solenoid relay does not work and in a very short time the starter will become unusable. To change a relay that is only responsible for turning on the starter, you need to stock up on: Where is the starter turn-on relay located? It is located in the engine compartment and is attached there to the car body using one single nut; in the photo below this relay is indicated by a red arrow, and the blue arrow shows the air pipe behind which this relay is located. When do you need to change the starter relay? There are some people who either don’t know the electrical part of their car well, or simply never look at this relay. They say it lasts forever and never breaks, we just want to say that many people, when they see that their car won’t start with the key, they immediately go to the starter, they remove it at the beginning, then replace the parts on it, remember for the future, you should always start with small and easily accessible things and only then go to hard-to-reach things and check them and change them if a malfunction is detected. If the starter relay fails, as we have already said, the car will not start and thereby respond to turns of the key in the ignition switch, the same will happen if the battery is weakly charged, and therefore if you suspect it, either charge it or change it to a new one if it is already very worn out, in addition, exactly the same situation. The car may not start due to the ignition switch, namely because of its contact group, but on cars with a relay when the starter is turned on, this rarely happens, because the relay It also unloads the contacts at the ignition switch and thus the contacts are less likely to burn out, but you can still read about how to check the contact group of the lock in the article entitled: For more detailed information about checking the relay using the example of a classic, see the videos below:. That’s why initially they don’t make such a relay on tens, it’s a very necessary thing, my friend has a 99 and I never remember that it couldn’t start the first time, but I have a ten and I have to constantly turn this starter and it even happens sometimes that it doesn’t It caught on the first time, now I’m going to install the same relay in my business car for five minutes, but it helps a lot.

How to deal with the VAZ unit

First, let's look at how to repair the starter with your own hands on VAZ cars. First, let's take the very first of the cars in this line.

To repair a VAZ 2101 with your own hands, we will use the tools listed below:

• set of wrenches;
• flathead and Phillips screwdrivers;
• sandpaper;
• heads.

So, let's start work by opening the hood.

1. Disconnect the terminals from the battery.
2. We dismantle the air filter housing with the filter element.
3. Unscrew the three nuts securing the electric motor to the motor.
4. We disconnect the wires after taking photographs of the connections.
5. We remove the defective device.
6. Perhaps the so-called “pants” - the exhaust pipe - will interfere with this, then you will have to unscrew the four bolts and “lower the pants”.
7. We separate the retractor cylinder from the dismantled element by disconnecting the wire and unscrewing three screws. We inspect it and, if necessary, replace it completely.
8. After unscrewing the bolts, remove the motor casing.
9. After unscrewing the two bolts, remove the cover.
10. Separate the windings from the brush holder plates and remove the insulating tube.
11. Separate the cover from the collector side.
12. Use a screwdriver to remove the motor brushes. We measure them and replace them if necessary.
13. We disassemble the drive of the defective assembly unit. To do this, undo the cotter pin, then remove the drive lever, disengage the drive from the clutch, and then remove it.
14. We inspect the windings of the electric motor.
15. If necessary, we press it out, and then replace the bushings of the assembly.
16. We clean elements with soot or plaque. We replace failed parts with new spare parts.
17. We carry out assembly and installation in the opposite direction.

Note that do-it-yourself starter repair for a VAZ 2106 is carried out according to similar instructions.

If we discuss the problem that interests us regarding front-wheel drive VAZs, then it is enough to simply consider what differences there are from the given instructions. The tools used here are the same.

However, for example, when repairing a VAZ 2109 starter yourself, you do not need to disconnect the exhaust pipe during removal from the car. Further manipulations are carried out exactly as described above.

Common causes of failure

Identification of starter components

If on a VAZ 2109 the injector or carburetor stops starting the engine, and the starter does not click, this may be due to various malfunctions.

In general, it should be noted that there can be several options for a malfunction of the starter unit:

If the injector does not start, and the starter unit makes only one click, the cause of the problem may be:

Starter unit "nine"

If the device clicks several times, but does not turn the engine and, accordingly, the VAZ 2109 does not start, then there may be several reasons:

You can turn the key as much as you like, but if the mechanism does not show any signs of life and the engine does not start, then the cause of the malfunction may be as follows:

If you have dismantled the mechanism and found no damage, try cleaning it and reinstalling it. It is quite possible that after this the VAZ 2109 starter will start working normally (the author of the video is the Avtoelektika HF channel).

Dismantling

There should be no problems with the dismantling process. The main thing here is to remove the starter, since the required relay is held on it. Therefore, dismantling is carried out as an assembly.

1. Turn on the handbrake, disconnect the battery by removing the negative terminal from it.
2. A wire with a large cross-section goes from the battery to the contact of the relay. It can be turned off by unscrewing it using a 13 key.
3. Remove the thin winding power wire from the solenoid relay.
4. Using the same 13mm wrench, unscrew the three mounting nuts holding the starter to the clutch block.
5. You can remove the device through the bottom or top. If you chose the top, then you need to slightly rotate the starter around its axis and remove it.
6. The lower output is more difficult, since here you need to remove the crankcase protection. But if parallel work is carried out that requires similar manipulations, problems will not arise.

Do you hear clicks or are there no traces of them? The driver releases the key and joy: the fan picks up speed. We take the sword and install it in the chuck of a hand drill: let's try to make a thread in the sleeve.

The owner turns the key to the third position, but again there is silence: the starter does not turn at all. The starter relay is located under the hood on the front panel. The VAZ-2108 and VAZ-2109 cars use a single-wire electrical system with a rated operating voltage of 12 V. This is truly a masterpiece of futurism!

Before examining specific cases, watch a video about repairing starters in a specialized service center. While you are enjoying the smell of iron, your significant other will buy a magazine where they will read an article about the history of the VAZ 2109 brand and regret that they purchased a non-domestic unit at a lower price. And we encountered the following difficulty: the starter does not turn when you turn the key, but at the same time you hear clicks, which means the retractor relay is working.

Causes and solutions to the problem

All faults can be divided into two categories:

• the breakdown lies in the starter and retractor relay;
• the starter armature rotates and the relay clicks;

The most common reason for a relay to not work is that the soldering point of the wire to the terminal has lost contact.
Before disassembling the device, just try soldering these places with a soldering iron - the problem is solved. Well, if the starter still does not work, then the relay will have to be disassembled. Sometimes the coil that creates the electromagnetic field burns out. Simply replacing the old wire with a new one eliminates the problem; to do this, you just need to rewind the coil with your own hands. In the second case, when you hear clicks, but the starter does not rotate, try bridging the terminals on the solenoid relay with a screwdriver with a rubberized handle. Having done this, the starter armature will start and begin to spin, you can easily understand this by the characteristic sound. In this case, the breakdown lies in the inability of the relay to pass electric current through itself. Be careful when working, because you are in an area of ​​electromagnetic activity and you may get an electric shock.

A few words about the nine starter

Before we learn how to use the repair kit for the starter we are interested in, let's figure out what this mechanism is. It is a simple electric motor with four poles and brushes, which is attached to the flywheel ring gear. The following starter models were installed on “nines” of different years of production: 29.3708; 5712.3708; 423.3708.

Any of them operates on a mixed excitation principle and has a traction relay with two windings. The differences between these starters lie in the design of the commutator device and the drive. Thus, the model 423 mechanism has a cylindrical type commutator, the 29 model has an end-mounted one, and the 5712 starter has a planetary gearbox installed in the drive. Their repair kit is absolutely identical, as well as their malfunctions.

Rare situations

They happen noticeably less frequently than those we described above. But under no circumstances should we exclude them.

After reviewing the situations below, compare them with the behavior of your starter and a car that has stopped turning or clicks but does not turn.

1. With an injection engine at a frosty temperature of about -20 degrees Celsius, all devices function. This indicates that the battery is fully charged. At the same time, for some reason the starter refuses to turn. Your actions:
   If there are no clicks when you try to start the engine, check the condition of the fuse, wiring and solenoid relay;
2. If there is a clicking noise, the most likely source of the problem is the solenoid relay. It must be replaced.

1. The engine started normally throughout the day, but in the evening it suddenly stopped working normally. When you turn the key in the ignition switch, there is only a click, but the starter does not turn. When you try to start the engine several times in a row, several clicks are heard. Your actions: Charge the battery;
2. Crimp, strip and tighten the contacts on the starter and battery;
3. If the first two points do not produce results, check the battery itself. To do this, the wire closes its contacts. If the battery is working properly, a spark will appear that melts the wire;
4. Connect the plus from the battery directly to the solenoid relay. If the starter is silent, replace the starter.

1. During the day the car started without problems. But after being idle for several minutes, attempts to start the car fail. When you turn the key, the relay is activated, but the starter stubbornly refuses to turn. By closing the two bolts of the solenoid relay, everything started. We reached our destination, stopped, and turned off the engine. When I try to start again, the same situation occurs. Just locking the bolts no longer works. Your actions:
   Disassemble the starter housing;
2. Check the condition of the brushes. There is a high probability that they have been completely erased. Hence this effect;
3. Replace the brushes with new ones. This is cheaper than completely replacing the unit.

1. The starter doesn't turn over. When you try to close it, only noise arises, like when a drill is working. The engine shows no signs of life. But it was possible to start it from the pushrod without any problems. Your actions:
   Make sure your starter is working properly;
2. If everything is fine with it, go to the mounting block and check the fuses;
3. Also examine the condition of the ignition switch. It is possible that the problem is with him;
4. Do not forget to check the wiring for breaks and short circuits;
5. Check the status of the contacts. It’s not uncommon that minus does not reach the starter relay only for the banal reason of oxidation or burnt wire.

We recommend: Antifreeze or antifreeze, which is better to fill and what is the difference?

Having understood the reasons for the failure of the starter, you can bring the device back to life on your own. Don't rush to throw away your old starter and buy a new one. The practice of VAZ 2109 owners shows that partial repairs, and sometimes even simple cleaning of the device, make it possible to restore the functionality of one of the main elements of the ignition system for a long time.

Design and principle of operation

Before you begin dismantling the starter, you should get acquainted with its structure. Then, based on the behavior of the device when starting the engine, it will be possible to assume possible problems. The BAZ 2109 starter consists of the following components:

• electric motor, to which direct current is supplied through 4 brushes;
• a freewheel with a gear that drives the engine flywheel;
• traction relay, necessary for extending the clutch with gear when turning on the electrical appliance.

In addition, motorists should be aware of the existence of bushings, due to which the rotor, coupling and gear rotate easily. One of the bushings is located inside the starter, and the second bushing is located in the clutch housing.

The operating principle of the starter is based on the conversion of an electrical signal into rotational movement of the drive gear. The brushes transmit electric current to the poles of the electric motor. At the same time, the clutch is extended and the gear is connected to the flywheel ring. To ensure the engine starts, the starter must be rotated lightly and quickly. After starting the engine, the starter clutch returns to its original position.

Why doesn't the VAZ 2109 starter turn?

In cases where, when starting the mechanism, you hear 2-3 clicks that follow each other, but the starter does not work, this may indicate the following problems: the terminals are loose or oxidized; The battery is discharged; The starter core is not fixed with a special holding winding.

If you hear only one click when you turn it on, and the starter does not fire, the reason lies in one of the following elements:

• in the winding (it has short-circuited);
• in Bendix (no voltage from the relay due to worn teeth);
• in the power bolts (most likely they are burnt, so the voltage is less than 12 volts);
• in the armature brushes or its bushing (they have worn out);
• in the fork, which is connected to the bendix (the fork does not push it through due to deformation or breakage, which leads to open contacts).

But when there are no clicks when starting, professionals recommend replacing the starter key or the ring that is located in the gearbox. Also, complete silence may indicate that a short circuit has occurred on the winding. Confirmation of short circuit Usually it is smoke and a noticeable “aroma” of burnt insulation.

Note that sometimes a prepared repair kit for repairing a starter may not be needed. The driver dismantles the mechanism to check its elements, tries to find faults, but sees that all of them, without exception, are in normal condition. In this case, it is recommended to put the repair kit aside and clean the starter components and then lubricate them. As a rule, the system begins to function again.

Solenoid relay design

To understand how to identify a malfunction, you first need to understand the design and operating principle of the retractor relay, as well as the starter relay, since they are located in the same housing.

So, there is a housing, inside of which two coils are installed - retracting and holding.

On the one hand, the body is covered with an ebonite or plastic cover. Three terminals for connecting wiring are installed on the outside of this cover.

One of the terminals is intended for connecting the “positive” wire from the battery, the second is for supplying electricity to the starter motor, and the third is for connecting the relay to the ignition switch.

On the inside of the cover there are two contact plates of the “positive” terminals.

Schematic diagram.

Inside the housing with the coils there is an armature, spring-loaded on one side, and a starter relay rod.

On the outside of the armature there is an eyelet, with which it engages with the Bendix fork and gear.

Alarm Signals

The starter is the highest-loaded electrical consumer in a car. If, when starting the car, an extraneous sound, noise, or crackling appears, or it becomes clear that there have been changes in the operation of the starter, action must be taken without delay. On a VAZ 2109, problems with the starter can be different, some of them can be fixed with your own hands by reading how to do it or watching a video. Here is a small instruction on faults.

If, however, the starter does not work on the VAZ 2109 and the problem is different, you need to contact a specialist.

Solutions

At first glance there is a lot, but nothing is impossible. What is made by human hands can definitely be repaired, and with the necessary knowledge and skills, this can be done much faster and with better quality. Good repair.

Hello, dear car enthusiasts! All. But, especially car enthusiasts of VAZ models. VAZ starters, despite their reliability, durability and endurance, still fail sooner or later.

The average starter life is usually 5-6 years, which is half the life of the engine. And whether it’s a malfunction of the VAZ 21093, VAZ 2109 or 21099 starter, the problem will still have to be solved by diagnosing, repairing, and possibly even replacing this electrical component.

Since the VAZ starter design differs only slightly, we will take into consideration the situation when the VAZ 2109, 21099 starter does not turn.

After turning the key in the ignition, you may find that:

What to do if the starter does not work? Of course, look for the cause of this phenomenon and try to eliminate it.

VAZ 2109, 21099 starter does not work after one click

Reasons why the VAZ 2109, 21099 starter does not turn,

after a single click, there may be several.

The fork that pushes out the starter bendix may be bent, broken, or otherwise deformed. In this situation, the bendix does not fully fit the flywheel; the cores only partially enter the coil, preventing the contacts from closing.

The teeth on the Bendix sprocket have worn out. Because of this, the solenoid relay cannot transmit voltage to the starter.

Also, the cause of the phenomenon of “one click” of the starter may be either the order of the armature bushings or a short circuit in the winding.

VAZ 2109, 21099 starter does not work after frequent clicks

Repeated clicks are repeated due to the fact that the retracting winding retracts the core, and the holding winding cannot hold it and lets go. This can continue until the battery runs out completely.

VAZ 2109.21099 starter does not work and there is no response to turning the key

The absence of any response from the starter to turning the key in the lock sometimes indicates a short circuit in the windings (if smoke and a burning smell appears from the starter when you try to start).

If the lack of starter response is not accompanied by “special effects” in the form of smoke and a characteristic odor, you should pay attention to the condition of the additional relay and the contacts of the battery terminals. The same reaction of the starter is observed when the ring in the starter gearbox is partially destroyed

The same reaction of the starter is observed when the ring in the starter gearbox is partially destroyed.

If the starter does not respond to turning the key in the lock, you need to take into account that the reason may lie in the key itself. If the check confirms this, it will be enough to just replace the ignition key to fix the problem.

It may also happen that after removing and disassembling the starter, you will not find any damage. Do not rush to replace it with a new one or go to a car service center. Perhaps after you clean the starter, apply new grease and reinstall it, it will come back to life.

After you find and fix the starter malfunction, try not to cause it to break down again in the future, because this lightweight device already has a hard time - the rotation of the massive flywheel and the start of movement of the entire piston group of the engine depend on its serviceability.

HOW TO CHECK WITH YOUR OWN HANDS

Without removing the starter from the car, you can only reliably check for poor contact and the fact that the retractor relay control circuit is faulty. If the starter does not respond to turning the key to the Start position, directly jumper the power terminals of the solenoid relay with a screwdriver. Triggering of the starter will indicate a malfunction in the control circuit or the traction relay itself.

If you know how to use a multimeter, in DC mode, check whether voltage comes to the control terminal after turning the ignition key to the Start position. If voltage is supplied, but the retractor does not operate (there is no characteristic click), the traction relay needs to be repaired or replaced.

Before disassembling, we recommend studying the structure and operating principle of a car starter. Also, when making repairs, it is important to understand the operating principle and diagnostic methods of the solenoid relay and starter bendix.

CHARACTERISTIC DAMAGES

• Abrasion of brushes that wear out due to tight pressing against the rotating armature. The degree of wear can be assessed visually or using a caliper. It is enough to compare the thickness of new brushes with worn elements.
• Wear of collector plates. Brushes wear out much faster than armature contact plates, but even after several hundred thousand kilometers they can become unusable. The degree of wear is determined by the depth of the groove, which is formed from friction with the brushes. If the brushes do not fit tightly at the moment of rotation of the armature, a spark discharge may occur, causing burnout and further detachment of parts of the lamellas. Among other defects that arise due to runout and axial play of the armature shaft are ovality and displacement of the friction zone of the brushes.
• Violation of the insulation of the commutator contacts, leading to breakdown of the armature housing to ground; interturn closure.
• Wear of the bushings securing the armature shaft. Critical depletion of bronze or copper-graphite bushings leads to runout of the armature shaft, as a result of which copper-graphite brushes fail much faster, and uneven wear of the commutator is observed. Also, wear of the bushings can cause displacement of the armature plates, which leads to an interturn short circuit.
• Wear or incorrect selection of spacer washers that prevent axial play of the armature shaft.
• Burning of the contact plate of the solenoid relay. Winding burnout, turn-to-turn short circuit of the solenoid coil.
• Worn armature shaft gear.
• Peeling off the magnets from the starter housing.
• Breaking the terminal of the positive wire coming from the power terminal retracting to the brush. Sometimes the terminals become severely corroded due to their location in an aggressive environment.

REPAIR OR REPLACE

Operations that in most cases are limited to manual repair of the starter:

• replacing the brush assembly. We have already looked at how to replace starter brushes with your own hands, so we will not dwell on this;
• cleaning the working area of ​​the collector with fine-grained sandpaper;
• lubrication of the planetary gearbox, armature shaft in the place where the retractor relay fork moves;
• complete cleaning of all parts from wear products of graphite brushes and commutator, dirt.

Many manufacturers do not provide for repair and maintenance of the solenoid relay, so to disassemble it, flare it. This can be done only for the purpose of cleaning the contact areas of the terminal bolts and plates with sandpaper or a file. If an inter-turn short circuit or a breakdown in the housing is detected, we recommend replacing it instead of doing it yourself. We also find the idea of ​​repairing the commutator lamellas and rewinding the starter armature very dubious. For widespread starter models, such repairs are simply unprofitable, since it is often easier to find a working used part at a disassembly site or buy a new starter altogether.

SAFETY PRECAUTIONS AND USEFUL TIPS

• Before removing terminals to repair or replace the starter, be sure to remove the terminal from the negative terminal of the battery.
• When checking a starter removed from a vehicle, securely fix it in a vice.
• Even to rotate the armature without engaging the flywheel crown, a considerable current is required, so when checking after repair, do not use thin wires and ensure reliable contact at the power terminals.
• You can find the tolerance limits for axial and radial play and the minimum collector diameter in the technical documentation. Even before starting repairs, we recommend that you find out the model of the starter, which should be indicated in the identification marking on the housing.
• When assembling, follow the sequence of installation of spacer washers that limit axial play. In order to assemble the starter correctly after repairing it yourself, make marks and take photographs during the disassembly process.
• Only the planetary gearbox needs to be lubricated. Grease for CV joints is well suited for these purposes. Do not lubricate the working surface of copper-graphite bushings under any circumstances. The grease will collect dust, thus turning into an abrasive paste.

MEASUREMENT OF AXIAL AND RADIAL PLAY

The armature shaft play should be checked before disassembly. To do this, just use your fingers to shake the shaft itself in the radial and axial direction. If there is significant play, it is necessary not only to replace the bushings, but also to measure the wear on the shaft itself, since in the case of critical wear, limiting the repair to only replacing the bushing will not bring much results. You can measure the axial play using a caliper. To accurately check radial play, use a dial indicator with a tripod.

CHECKING THE ANCHOR

The video shows a simple way to check turn-to-turn ignition. The essence of the diagnosis is to connect one of the contacts of the light bulb to the armature shaft. The second contact should be made along the collector lamellas. If there is no breakdown to the body, the light bulb will not light up.

Possible causes of failure of the VAZ 2109 starter.

So, there are actually quite a lot of situations in which the starter stops working. For example, if you are trying to start your car and you hear a clicking noise, there may be a problem with the car's fuse or wiring. It may also not work yet, or the reason may lie in the wear of the bushings. In such a situation, I recommend checking the contacts on the relay, since they may simply oxidize. But first of all, make sure the battery is working, I advise you to read my articles:

To do this, simply turn on the lights and/or hazard lights. If you can do this, it means the battery is charged and working properly.

When it's the starter

If after these steps the starter continues to be silent, it means it is broken. To repair it, you need to disassemble the solenoid relay. But how to do this if the mechanism itself is not intended for disassembly? In an old-style relay, you need to unscrew one or two screws and unsolder the wiring that goes inside the device.

Modern devices are non-separable, and in order to open the back panel, you will have to flare the metal body of the mechanism. Flaring can be done with a large screwdriver or pliers. After this you need to remove the cover. To repair, clean the burnt contact plate and the surfaces of the bolts from soot to a shine. The better you clean it, the longer the relay will last you.

Of course, it would be wiser and safer to go to the nearest service station, but for a number of reasons, drivers sometimes repair the car themselves. Saving money and time requires preliminary preparation and certain knowledge in machine repair.

Starter device, principle of its operation

The starter of the VAZ-2114 car (factory index - 5712.3708) is a DC power electric motor, additionally equipped with an overrunning clutch with a gear (Bendix) and a retractor relay.

The principle of its operation is very simple: when the ignition is turned on, voltage is supplied to the solenoid relay. Due to the creation of a magnetic field in it, the armature connected to the plug is retracted.

This fork moves the bendix along the rotor shaft of the electric motor and engages the gear with the flywheel ring gear.

In this case, the armature, fully entering the relay, closes the contacts, and voltage is already supplied to the electric motor itself, which is switched on.

The task of the overrunning clutch is also to protect the electric motor. After starting the power plant, the rotation speed of the flywheel significantly exceeds the speed of the gear. It turns out the opposite effect - the flywheel turns the gear.

And so that the force is not transmitted back, after exceeding the speed of rotation of the electric motor, the gear begins to rotate freely on the shaft until the driver turns off the power to the retractor relay, after which the spring returns the bendix to its original position, disengaging the gear.

Element Role

All VAZ cars, including model 2109, have a standard engine starting system, which is based on an electric starter. Here's what you need to know about him.

1. A starter is a small electric motor that is connected to the flywheel of the motor via a coupling (Bendix) for a short period of time to start the rotation of the flywheel.
2. Despite its small dimensions, the starter passes through itself enormous currents.
3. If the starter circuit were closed directly in the ignition switch, then not a single component of the system would be able to withstand such current loads. As a result, they would burn out.
4. Therefore, for these purposes, the starter is connected remotely to the battery via a relay. Its contacts are designed for high currents.
5. The starter operates briefly and must be turned off after the engine starts. Otherwise, its active destruction will begin due to the influence of motor power.
6. Relyushka performs these tasks perfectly. Actually, it is precisely to ensure the functioning of the system and protection against current, timely shutdown of the starter, a retractor relay is included in the design.

Individual situations

If the VAZ 21099 injector stops starting, you can try to close the contacts of the mechanism in a straight line.

But sometimes there are emergency situations when the device stops functioning, let’s consider a few of them:

1. The injection engine does not start in cold weather, but all devices work normally, the battery is charged. If there is no click, you should first diagnose the safety components, electrical circuit, and also the solenoid relay. If the device clicks, the relay must be replaced.
2. all day, there was a spark, but in the evening the engine stopped starting. Before, you need to fully charge the battery, and then clean the contacts both on the battery and on the mechanism itself. If these steps did not help solve the problem, you need to check the battery itself more carefully - try closing the contacts with a wire, which may cause a spark to melt. If this does not help, try applying a positive charge from the battery directly to the relay. If there are no changes, the unit will have to be replaced.
3. If the car was operated normally all day, but after parking for five minutes it stopped starting, you can try to close the mechanism. You need to directly close two bolts on the relay; if this helps, but later the problem reappears, then disassemble the unit completely. Most likely, the problem lies directly in the erasing of the brushes. In this case, they will need to be changed.
4. The unit does not turn at all, but the car can be started from the pushrod. If the problem is not with the starter, then check the fuse box and ignition switch. But before this, you should check the wiring - the reason may lie in the oxidation of the contacts.

A starter, without it you can’t start the car, which means you won’t go far. The success of the trip depends on its performance. Therefore, you need to figure out how to prevent its failure, or fix an existing breakdown. Let's take a closer look:

• Alarm Signals
• Malfunctions

Checking status

Before changing the relay, make sure that the problem with starting the engine is related to this component.

To do this, consider two situations that indicate its malfunction.

Having discovered that the relay has served its purpose, it must be replaced or repaired, if possible.

Functions of the VAZ-2109 stove fan

The VAZ-2109 car heater is designed to heat the vehicle interior. It also helps get rid of glass fogging from inside the car. Its heating power is designed to ensure that at 25 degrees below zero, an optimal thermal regime will be maintained inside the car - from 16 degrees Celsius.

One of the main elements of a car heater is a fan. It is needed in order to drive air from the external environment, which enters the heating device through the radiator. Cold air undergoes a warm-up procedure and enters the car interior already warm.
