Wiring diagram of the starter VAZ 2110 injector 16 valves with description

VAZ starter connection diagram

VAZ cars use starters, which are a DC electric motor with an electromagnetic two-winding traction relay and a roller freewheel clutch (overrunning clutch). Starters are used to provide the minimum crankshaft speed required to start the engine. The starter is powered in starting mode from the battery.

The starter relay is connected to the power circuit, thereby closing and opening the circuit, depending on how fast the crankshaft rotates. The starter design on all cars is the same, with only minor design differences. If you understand how the starter works in one car, you can easily figure it out in another.

To prevent a starter failure from taking you by surprise, let’s look at how to replace it yourself. But first, read the theory and study all the options for starter connection diagrams for different models of VAZ cars, collected by the editors of 2 Schemes.ru from familiar auto electricians.

How to install an additional starter relay on a VAZ 2110 Assembly diagram

Until the year 2003, the ignition system of VAZ cars was one of the weakest points in the on-board electrical network. This is due to the generation of high voltage and the inability to unload the starter unit. To solve the problem of a weak starter, vehicle designers and developers adopted the VAZ 2110 auxiliary starter relay.

What exactly does installing an additional relay do?

1. Relieves the contact group in the ignition switch
2. Prevents sintering of starter contacts due to prolonged ignition
3. Opens the electrical circuit when the engine has already started and the ignition key is in the “starter” position

Of course, the additional starter relay for the VAZ 2110 (diagram in the photo) is not a panacea for all the ills of on-board electronics. Experienced experts recommend modernizing the electrical network comprehensively. The list of work may include installation of capacitors, installation of an auxiliary battery, replacement of mass, and other, other work.

To this we can add that not even all the latest modifications of this car have a wiring diagram for the VAZ 2110 starter. If the on-board electrical circuit is well balanced and designed, then an additional relay is not needed at all.

How to check for the presence of an additional relay in the starter?

If you depress the gas pedal and turn the key to the “starter” position, after 12 seconds the starter will automatically turn off. This activates the cylinder purging mode. That is, fuel is not supplied to the working chamber.

If the starter does not turn off, then the relay is missing. In this case, it is advisable to install an additional VAZ 2110 starter relay (the connection diagram is noted in the instructions for this review).

What is needed to install an additional relay?

1. Relay with 4 contacts with current strength from 30 to 40 (A). The most commonly used is the 30 amp relay.
2. Reinforcement with a cross-section around 1.5 (mm2)
3. Flat female connectors (5 pcs)
4. Flat male connector (1 pc)
5. Ring connectors for 6 and 8 (mm)

When the materials are prepared, let's look at how to connect the starter relay. By the way, there is an intelligible video on this topic:

Please note that car dealerships sell ready-to-install additional relay kits. This set contains both good wire and high-quality ring connectors

All elements are marked and made in the same style. It is easy and pleasant to work with such materials yourself.

Under normal loads, the current generated by the starter is 150 A. When heavy loads occur, for example in winter, the resulting current can reach 500 A. This is a serious test for this electrical unit, so it is not recommended to keep the key on the start for more than 10 seconds, and repeated starting attempts must be made with a break of at least a minute.

DIY starter repair

Maintenance or repair of the starter must be carried out in accordance with certain algorithms, compliance with which requires certain experience and knowledge, as well as the use of the necessary tools. Troubleshooting always begins with disassembling the starter, after which diagnostics are carried out, and if problems are detected, repairs are carried out.

Tools and Supplies

To troubleshoot, you need to prepare the following tools:

1. Socket heads for 13 and 15.
2. Extension.
3. Handle equipped with a ratchet.
4. Ohmmeter.
5. A special analyzer equipped with a light bulb.
6. Phillips and flathead screwdrivers.

Spare parts will be used as consumables to replace failed components. You can determine which parts require replacement at the diagnostic stage described above. To repair the starter, it is recommended to use only high-quality parts.

How to remove and disassemble

To prepare for repairs, it is necessary to completely disassemble the starter. This procedure should be carried out in the following sequence:

1. Remove the negative battery terminal.
2. Remove the air filter housing to ensure convenience for further operations.
3. Disconnect the wire leading to the traction relay.
4. Place the disconnected wiring to the side so that it does not interfere with further repairs.
5. Unscrew the nuts that secure the starter to the gearbox.
6. Remove the unit and carry out further repairs in more convenient conditions.
7. Disconnect the wire that is in contact with the mounting bolt.
8. Remove the traction relay. To do this, you need to unscrew the two bolts that secure it.
9. Remove the relay armature. To do this, you need to lift it up a little, and then remove the loop from the lever.
10. Unscrew the nuts securing the tie rods.
11. Remove the cover with the drive, as well as the gearbox assembly.
12. Completely “remove” the tie rods. This will make it easier to further remove the drive and gearbox.
13. Remove the planetary gears. They need to be replaced if there is damage to the teeth or the integrity of the needle bearings is compromised.
14. Replace the brush holder assembly (if necessary).
15. Remove the cover from the manifold side.
16. Unscrew the two screws and then remove the brush holder from the cover.
17. Bend the clips and remove the spring.
18. Check the anchor for defects. To do this, you need to remove it from the case.
19. Remove the gear from the anchor shaft.
20. Remove the armature from the stator mechanism.
21. Remove the sealing support from the lever.
22. Knock the stopper off the retaining ring using a special mandrel.
23. Dismantle the restrictor and retaining rings.
24. Remove the drive assembly.

General view of a completely disassembled starter

Assembly must be done in reverse order.

Troubleshooting

When conducting a full check of the functionality of the VAZ 2110 starter, you must act in accordance with the following algorithm:

1. Check how well the unit rotates. If the crankshaft moves poorly, you should pay attention to the presence of lubricant and, if necessary, lubricate the mechanisms. There are situations when the oil does not correspond to the current season. Replacing it with a more suitable one will solve the problem.
2. Check the battery for charge and oxidation of tips and inputs. If necessary, it is necessary to charge and replace failed elements. In such a situation, it is necessary to carry out maintenance of the contact group and the battery itself, after which the functioning of the starter will be restored.
3. Inspect the brushes and check the tightness of the wire ends. To do all the necessary actions, you will need to dismantle and disassemble the device, clean the commutator, replace the brushes and adjust the degree of spring tension.
4. Determine the presence or absence of clutch slipping. If necessary, it is necessary to completely replace the starter drive. Another way to solve the problem is to wash the threaded shaft and then lubricate it.
5. Inspect the flywheel ring teeth for nicks. Their presence may be indicated by a characteristic grinding sound. To eliminate it, you will need to eliminate the nicks or install a new buffer spring if the old one is noticeably weakened.
6. Carry out diagnostics of the starter pole fastening. Its weakening may be indicated by the characteristic noise present during operation of the mechanism. The problem can be solved by securely fastening the starter or reinforcing the said fastening.

To ensure that the bolt is in contact with the plate, it is necessary to measure the resistance on the contact bolts

If you check using the described algorithm, you will be able to accurately determine the “source” of the malfunction and effectively eliminate it. However, there are breakdowns that cannot be eliminated during an inspection.

Where is the starter on a VAZ 2112 16 valves?

Dear visitors of the site “All about cars”! We will be very grateful to you for your comments on the video clip “Where is the starter on the VAZ 2112 16 valves”, registration is not required for this. We also ask you to let us know if you have any problems playing the video.

Well, what was the reason? Contact group or relay 

What couldn’t be checked with a screwdriver? without removing the starter 

the anchor burned out there after all, I still initially sinned on the solenoid relay

It would be useless, because I wouldn’t shoot another video because of this. It burned out completely.

The other day the starter also stopped working. VAZ 2114 was standard Belarusian. Didn't even bother with the repairs. I bought a new KOTEK for 3t. R. It starts with a click and buzzes like a bee. I advise everyone 

I’m a teapot, where else can I put the air down if there’s no snowdrift nearby?

4. 28 than the reason

The battery must be disconnected before removing the air flow sensor chip, and not after. So you can burn it. 

But I still didn’t take any risks and postponed the repairs until the winter, which I advise you to do as well.

The video needs to be renamed. The title does not match the content. How did you remove the bottom mount? The name of the video is repairing the starter or the reasons for the starter dying. 

Before removing the MAF chip, you need to remove the terminal from the battery, otherwise you can then buy a new one.

Change the ignition switch, same thing happened.

Why show the left details, something like an air blower, it’s already clear to everyone what it looks like and how to shoot it….

What was the problem?

And I add. I plugged in the relay and everything worked for me. I connected the lamp to the red wire before - the current was flowing... But the current was weak. I still haven't found the ignition relay. Therefore, the most likely cause is the ignition switch. But this is a disease, as I understand it, in the tags. So it's better to add extra. relay. The current on the wires drops less and the chisel starts up faster now: There is really a possibility that the connector is simply stuck on the retractor. Emery solves this problem. 

So what was the reason? What's next? -Egnition lock? -Wiring? 

write why do you need to remove the hood lock wire? and how to unscrew the starter bolt from below if there is no pit, lift, or garage. 

the importance is in the little things, but they are not there, what and how to unscrew is not said or shown, there is no point in the video, I filmed it for one, don’t make it accessible to everyone, there is so much garbage on the Internet

Starter circuit for VAZ 2110, 2111, 2112

Starters of type 57.3708 were installed on VAZ-2110 cars and had the following technical characteristics:

• Rated power 1.55 kW
• Current consumption at maximum power no more than 375 Amperes
• Current consumption in the inhibited state is no more than 700 Amperes
• Current consumption in idle mode no more than 80 Amperes

The connection diagram for the starter for the ten is shown above, here is its explanation:

1. battery
2. generator
3. the starter itself
4. egnition lock

Some design features

The part in question consists of the following elements:

• Steel electric motor. Its purpose is to remove heat. In addition, it is characterized by water-repellent characteristics. This circumstance ensures that there is a situation in which you can wash the engine without any fear. Water will not be able to penetrate current-carrying parts, and therefore will not cause harm.
• The housing is the location of the solenoid relay. The flywheel and gear are fixed using its lever. This ensures that torque is transmitted. Copper contacts are connected to the core. They transmit voltage from the battery.
• The anchor is the attachment point for the commutator elements, windings, and gears.
• When the car is started, the flywheel is connected to the starter via a bendix. As soon as the car starts, all elements return to their original position.
• The brushes are fixed with holders and allow them to be quickly replaced if necessary.

The starter is fully functional thanks to the presence of two relays. They should be clearly distinguished from each other. The first element is used to turn on the starter. The second device is a pull-in relay. It is located directly on the starter. For VAZ 2110, the starter relay is of great importance for the operation of the tens.

This device is intended for the following purposes:

1. Thanks to it, after starting the engine, the gear returns to its original position.
2. The energy required by the starter motor and the electromagnetic relay is redistributed.
3. The bendix gear is fed.
4. Thanks to the device, all parts work synchronously when the engine starts.

It should be said that this part fails quite often, so the VAZ 2110 starter relay needs to be replaced. But getting to it is not so easy. In this case, you will need to disassemble the starter itself.

Starter solenoid relay

The starter relay is called a pull-in relay. This is due to the principle of its operation - it performs the function of connecting the starting device to the electrical circuit and connecting its armature to the crankshaft. It happens like this: when no current is supplied to the windings of the device, its armature, under the action of the return spring, remains in the forward position. The same spring, through a special fork, holds the Bendix gear, preventing it from engaging with the crankshaft flywheel ring.

By turning the key in the ignition, we supply current to the winding of the device. Under the influence of an electromagnetic field, the armature is fed back (pulled into the housing), closing the starter power contacts. The Bendix gear also moves, engaging with the flywheel. At the same moment, the retracting winding is turned off, and the holding winding comes into play. The force from the starter shaft is transmitted through the gear to the flywheel, causing the crankshaft to rotate until we no longer hold the ignition key in the start position.

What functions does the solenoid relay perform:

• Protects the starter from shorting contacts in the ignition.
• In order to turn off the power to the starter in a situation where the engine is running and the key shows the “starter” mode.
• Provides relief of contacts in the ignition switch.

When the engine starts, voltage from the generator goes to the relay coil. Then the gears of the drive system begin to work, due to which a magnetic field is created. The flywheel of the propulsion system is working. The gear begins its work thanks to the holding winding, while the bolts are closed. When the key is returned to the ignition switch, the winding is de-energized, thus disconnecting the gear and flywheel. This scheme applies to modern cars, including VAZ models.

If the starter makes a loud noise, the pole or starter could be loose. In the first situation, strengthen the fastening by tightening the screw, and in the second, secure the starter. If you disassemble the starter and see that the clutch is starting to slip, then the only thing you need to do is replace the starter drive.

The principle of operation of the starter and its main elements

With the help of the starter, the primary rotation of the engine crankshaft begins until the power unit starts up due to the ignition of the oxygen-gasoline mixture. This electric machine is a constant current EDC with 4 brushes of a four-pole type, which initiates the excitation moment using permanently installed magnetic elements, so replacing the VAZ 2110 starter is necessary in case of its failure.

It includes a freely rotating roller-type clutch, a traction relay with 2 windings, and a planetary gearbox. The traction relay with 2 windings is the most significant element of the starter. With its help, the drive gear is brought into engagement with the rim of the motor flywheel. In addition, it determines how the starter motor receives power.

VAZ 2110 diagram

Colored wiring diagrams for the VAZ 2110 (injector and carburetor engine) are provided with a description of all elements for various modifications. The information is intended for self-repair of the car. Electrical circuits are divided into several blocks for ease of viewing via a computer or smartphone; there are also circuits in the form of a single picture with a description of the elements - for printing on a printer in one sheet.

There are two types of electrical wiring for the VAZ-2110: carburetor and injector. There are slight differences, but the basic principles of operation and wiring are the same. Depending on the location, the wiring differs into: under the hood and in the cabin. All electrical equipment of the car is connected using wires of a certain color. Each element has its own wiring harness through the blocks and fuses.

Starter replacement

You can remove the starter yourself, as the procedure is quite simple. You need to start by preparing the tools for work.

Required tools:

• Extension.
• Handle with ratchet.
• Socket head for 15 and 13 mm.

Attention! Removal can begin after disconnecting the negative terminal from the battery. This applies not only to dismantling the starter, but also to any other work related to electricity.

To make the process easier, you need to remove the air filter housing.

The next step is to disconnect the wiring from the solenoid relay. It is important to ensure that the positive wire is also unscrewed from the terminal. The photo shows the elements that we need to dismantle.

If it is no longer possible to repair the VAZ 2110 starter yourself, then replace it with a new unit yourself in the reverse order.

Communities VAZ Repair and Modification Blog Installing an additional starter relay

I read on the forums, I’m not the only one with a similar problem, maybe it will help someone else. I suffered for a long time with the problem of starting the car while it was hot. The problem was especially noticeable in the summer. At times the starter simply refused to turn, you turn the key, there’s a click, the instrument panel dims a little and that’s it... the starter is silent. The problem is not constant, this can happen once a week, maybe every other day. You can drive the car all day, turn it off, start it, everything works, and at some inopportune moment it stops responding to the key. You stop at a gas station or at a store and that’s it. You start running with a screwdriver into the hood and closing the contacts on the retractor, and it starts with a screwdriver. If you start it with a screwdriver and then turn it off, you can start it with the key without any problems and again you can drive for an unknown number of days or hours, etc. To. The problem is floating and intermittent. During the search for the cause, I went through the starter, changed the brushes, installed a new retractor (but in vain), cleaned all the contacts, cleaned the contact group of the ignition switch. I did all this in stages because After each action, the problem seems to disappear, but only for a while, you drive for a month and again it’s unexpected. As I found out, the problem arose at the slightest drain of the battery, like turning on a Carlson, when the engine warms up or listening to music with the engine off. After that, there was simply not enough voltage through the ignition switch, somewhere there was apparently a voltage loss from bad contacts, perhaps the contact group needed to be changed and not cleaned (but it’s not a fact that a new one would have lasted a long time). I decided to install a starter relay and at the same time I made additional mass .I bought a 4-pin 30A relay, five female connectors, one male connector and a couple of ring connectors.

I took out the BPVL 4.0 cable from the cradles. I made it in three layers, crimped it and tinned the contacts and covered everything on top with corrugation. I threw the mass onto the generator and onto the starter. I also replaced the original mass of the body, it was too flimsy.

According to the scheme described above, fuel regulation in a car is carried out. Moreover, it depends not only on the load of the valves in the engine, but also on the corresponding position relative to the throttle valve. With the help of a diagram of electrical wiring and valves, it is possible to understand which of the relays or fuses is malfunctioning and replace it in time. In this case, one of the main roles when supplying fuel is played by electrical equipment (controllers) that regulates the operation of the injector.

Where is the Starter Relay for VAZ 2115 Injector?

Starter relay VAZ 2115

The most likely cause of starter failure is electrical damage.

When the engine starts unsuccessfully for the first time, most people look for a problem in the starter, which is not always correct. The operation of the starter directly depends on the relay, contact connections and the availability of the necessary electricity. To check if the electric starter is working, it can be powered directly from the battery by connecting the positive wire from the terminal.

This way, you can start the engine to continue driving with a faulty starter power system. Many people try to find a VAZ 2115 starter relay in a car, where there is a component of the car’s electronic system, but the search does not produce results. This happens for the simple reason of its absence.

Perhaps the VAZ manufacturer is already equipping the new series of cars with a starter relay, but previous versions of these cars were manufactured without it. This is not critical, since the cost is negligible and the benefits are immediately visible; you can install it yourself, without the skills of an electrician.

Why is it necessary to install an additional VAZ 2115 starter relay? An additional relay ensures more stable operation of the starter with additional electrical equipment. Thus, the starter works even with a weakly charged battery, the backlight on and at low temperatures.

VAZ 2115 does not turn the starter, fix the problem

Installing the relay

for
starter
and 2110.

Do not confuse the VAZ 2115 starter relay with the repeater, which is located on the starter and performs the function of pushing and retracting the mechanism for engaging the starter teeth and the flywheel. Thus, a normal car start. Retractor malfunctions are expressed in the following manifestations:

• After the engine has started successfully, you may hear the starter whirring.
• Turn the ignition key with a simple click, the starter does not work
• try to start the engine with the key

Such manifestations are characterized by a violation of the starter and replacement of the relay.

Repair of the retractor starting relay VAZ 2115

First remove the starter by unscrewing the mounting bolts and before disconnecting the battery. Remember. The main thing. ensure the safety of repairs. After successfully removing the electric starter, you need to unscrew the solenoid relay bolts.

In most cases, the relay relay will not fold, but it can still be repaired. To do this, you will need a screwdriver, a soldering iron, a copper winding, a core, which, if you look, may turn out to be intact. In this case, you don't need to change it.

When soldering the wire with a soldering iron, you can move on to expanding the coil body. By separating the coil, you can determine its damage and replace the necessary elements.
