The VAZ 2114 solenoid relay is a unit (part of the starter, of course) that is controlled by the transit current of the ignition switch, designed to regulate the chain reaction with a current greater than the current from the ignition. It is also important because without it there will be no moment of coupling between the clutch and the engine.
starter retractor relay VAZ 2114
More than once it was advised to deal with the filling of the hood of the fourteenth yourself, in this case there will be no abandonment of tradition. The retractor relay is located directly on the starter, having two wires: a thin red one (with low current from the ignition switch) and a thick positive contact from the car's charging battery.
Where is the VAZ 2114 solenoid relay located?
The starter device on the VAZ 2114 model is not much different from other cars of this brand. The fairly simple design of the motor starter allows it to serve for a long time without breakdowns. Jamming and complete failure of the retractor relay makes normal use of the starter impossible. To replace it yourself, you need to know the location of the relay. The photo below shows the exact location of the retractor element.
The photo shows the assembled device. At the top of the picture there is a cylinder to which the power wire goes. This part is the solenoid relay. With some manipulations, dismantling the part takes about 10 minutes. Quick replacement of the VAZ 2114 starter relay is possible due to the convenient location of the element. If desired, you can completely dismantle the part and start replacing the spare part.
Video that clearly demonstrates the replacement process:
The main task of the solenoid relay is to close the circuit in a timely manner. When you turn the key in the ignition switch, the core located in the relay housing is activated. Next, this core drives the bendix, which leads to the operation of the rotor. The gears together with the bendix drive the flywheel. As soon as the engine starts, the driver turns the key to the initial position and the circuit opens.

REPAIR
It is advisable to repair the VAZ 2114 starter solenoid relay when the structure is collapsible, and when it makes sense to repair it.
Often the cause of VR failure is jamming of the core in the device body. This defect appears due to dryness inside the case. It is enough to lubricate the core with liquid oil (for example, motor oil), and the part will continue to serve properly for a long time. During repairs, it is also necessary to clean the contacts or, if necessary, replace them.
Checking the functionality of the solenoid relay with the starter removed is carried out as follows:
- A ground wire is “thrown” onto the starter housing from the negative terminal of the battery;
- We connect the positive wire on one side to the “plus” terminal of the battery, and on the starter we connect the wire to the upper contact on the solenoid relay (where there is a thread for the nut, but not to be confused with the lower contact that secures the stator winding):
- Then we take a piece of wiring, and from the top terminal we supply power to the smallest contact on the VR (it is this that receives power from the ignition switch);
- If the VR is working properly, it should work and the starter will start spinning.
Relay 2114 can serve for quite a long time, but it can often fail due to overloads. For example, if the engine does not start immediately and you have to turn the starter for a long time, the contacts on the VR may overheat and burn out. It should also be remembered that the VAZ car itself is Russian-made, and the quality of domestic spare parts may not always be at the proper level.
Signs of malfunction of the VAZ 2114 retractor relay
The difference between a breakdown of the solenoid relay is that it does not happen unnoticed. Even a faulty element can perform its function for some time. The difficulty of starting the engine if the device is worn out will depend on the number of attempts to turn on the starter.
In frosty weather, this problem will become more pressing, because... Poor VR operation will quickly drain the battery. Before carrying out work to replace a part, you need to make sure that the breakdown is accurately diagnosed. To do this, you need to know the signs of a malfunction in the VAZ 2114 VR:
- When the key is turned to the position of supplying power to the starter, a characteristic buzzing sound is observed, indicating that the starter is not engaging with the flywheel;
- There are clicks from the starter device, but it does not turn on;
- When the engine is running, the unit continues to operate and does not turn off even when the key is turned to the initial position.
It is recommended to replace the VAZ 2114 starter solenoid relay if one of the problems occurs. Sticking the starter in the on position accelerates its wear. Where the unit's bendix is located, there should be maximum engagement with the flywheel, so slipping is unacceptable. The design of the starting device is made taking into account a short period of continuous operation, so sticking when turned on wears it out.

STARTER DEVICE 2114
Like the starting device for any other passenger car, the 2114 starter consists of the following parts:
- Main building;
- Stator (winding placed along the diameter of the housing inside);
- A rotor (or armature) rotating in two bushings;
- Brush unit. He commands the rotation of the rotor;
- Bendix (gear that meshes with the flywheel of an internal combustion engine);
- Bendix fork;
- Solenoid relay that controls the bendix.
Necessary tool
Without tools, dismantling and installing a new part cannot be accomplished. The procedure for removing the solenoid relay or starter assembly requires a simple set of wrenches. The following tools will be useful for trouble-free work:
- Socket wrench and open-end wrench 13.
- Phillips and flat head screwdrivers.
- Key for 10.
- New retractor.
A simple set with all types of keys will be useful to any driver, because... No one is immune from sudden breakdowns of VAZ cars. The advantage of the 2114 model is that repairing most components is cheap, and even a novice driver can change the retractor on a VAZ 2114.
Principle of operation
The battery powers the starter coil, which, in turn, acts on the armature under the influence of a magnetic field. It moves and compresses the spring (return), causing the bendix to mate with the splines on the flywheel. At the moment the contact elements close, the retractor winding remains without power, and the magnetic field holds the armature inside the system. Then, after the elements are closed and the engine is started, power stops flowing to the holder coil, and the armature falls into place, as a spring acts on it (as a result, the bendix disengages).
Where is the starter relay located on a VAZ 2114
Having understood the principle of operation and determined the place where the starter relay is located on the VAZ, we look at how it can annoy the owner of the fourteenth.
Replacing the solenoid relay on a VAZ 2114
If there is a problem with normal engine starting, you should repair the starter device. First of all, prepare the tool and work area. For normal dismantling, you can free up space under the hood by removing the air filter housing. Next, the replacement process can be described in several steps:
- Remove the terminals from the battery for safe operation.
- Disconnect the power plugs.
- Using a 13mm wrench, unscrew the terminal screwed to the starter housing.
- Unscrew the fastenings of the main body of the unit (3 nuts by 13).
- Remove the unit from the seat and use a size 13 wrench to unscrew the wire from the cover.
- Unscrew the screws securing the solenoid relay with a screwdriver and remove the part.
It is recommended to install only a new one in place of the old device. Even if there is a slight malfunction of the device in the core, the housing assembly should be replaced. It is clear that this approach may not be suitable for some, but the cost of this device is not so high that you can try to restore its operation using improvised means.

Functionality check
Still, despite the obvious symptoms of wear on the draft relay, you can make a mistake with your conclusions. Therefore, let's first check the starter. Having installed a new solenoid relay, there is a high probability that if something does not work, it will be the starter.
Turn the key in the ignition, the starter should start to wind, the relay click should be heard. In a situation. If the starter fails, you need to change it, not the relay.
We check the traction device itself in this way: we attach two contacts to its back cover (these are copper bolts), the starter winds - the traction relay is definitely faulty. By the way, there is no need to remove the starter, this way the readings will be more accurate.
If you still removed the entire system. Then the actions are as follows: we match the wiring of the contact of the draft relay with the positive of the battery, with another contact we match the battery charger and the ground of the starter. When the contacts touch the marks of the relay, it should respond and start working, with a click before the process. If it works, but as if in slow motion, check the contacts, they could oxidize or burn out.
In order not to spend extra money in the store and not to buy a new retractor, if suddenly the problem is not in it, there is a simple way to distinguish a breakdown of the starter from a breakdown of its pull relay.
Price of the retractor relay VAZ 2114
The new design part is manufactured by several companies. Let's consider several product options:
- Spare part from . Quite a quality option. Price – approx. 600-700 rubles.
- The analogue version from the Belarusian can be purchased at a price 500-700 rubles, depending on the region. Medium quality.
- The highest quality VR option from – 1000 rubles.
When searching for a spare part, be careful, because... There are often fakes.
Malfunctions
Everything is obvious here: charred wires, stuck contacts, burnt windings, and general wear and tear also happens. So that trouble does not take you by surprise, you need to listen to the symptoms of the imminent death of the draft relay:
- The engine starts, but the starter continues to spin. Its sound is unnatural and loud.
- On the contrary, the ignition is turned on, but the starter does not turn. Although the click of the relay was audible.
- The ignition works, the starter idles because the engine does not respond.
The pull rod on the unit can be disassembled, although most often not (especially after nine). You can understand the structure of the device itself by replacing the failed part, but it is better to take a new one.
The price of the VAZ 2114 starter solenoid relay is from 300 to 600 rubles, depending on the region of the country.
Differences between starter and relay failure
In order not to confuse what exactly has failed - the starter or the solenoid relay, there is an excellent method for recognizing the “culprit”.
- Remove the starter, connect the negative terminal of the battery to ground;
- The design of the device has copper bolts and a tongue-shaped element;
- The positive wire from the battery is connected to this “tongue”;
- If there is contact, the solenoid relay clicks and starts working;
- If not, then you will have to go to the store for a new relay.
The performance of the starter can be checked differently. To do this, the negative wire from the battery is attached to the starter ground, and the positive wire is attached to a bolt (contact goes from it to the solenoid relay). If the starter starts turning, then everything is fine. Your hypothesis about the problem relay was once again confirmed. Just before checking, make sure that the contacts themselves are in good condition and not damaged. Many people forget about this, which leads to incorrect conclusions regarding the performance of the two elements.
But there is one more very important point. Even if all the facts indicate that the starter or retractor relay is not working, another unit - the ignition switch - may still be the cause of ignition problems. Take the time to check its serviceability before buying new parts.
Other relay
We figured out where the starter relay is located on the VAZ-2114 and how to replace it. But in the engine starting system there is another part with the same name. Yes, yes, it is also called the “starter relay”. Only extra. And its function is completely different. An additional starter relay serves to ensure the safety of the entire starting mechanism. Without it, the brushes and armature windings would burn almost every time it was started.
You will ask again, where is the starter relay located on the VAZ-2114? On the first models of the “fourteenth” it was located in the engine compartment at the top on the partition separating the engine compartment and the interior. On the new VAZ-2114 it is not there. And some “experts” foam at the mouth and prove that cars of the Samara-2 family do not have it at all.
In fact, there is an additional relay, but it is located under the steering column. Just remove the bottom part of the plastic casing and you will immediately see it. This is a regular four-pin relay labeled 98.3777-10 that protects the starter circuit. If you have problems starting the power unit, do not be lazy to check it too.
Connection diagram
From the photo it is not difficult to determine where the starter switch is located on the fourteenth VAZ model. This element is located directly on the starter and has two wires:
- The first is red and thin, a small current from the ignition switch passes through it;
- The second thick positive one comes from the battery.
