Where is the starter relay on the VAZ-2114? Possible breakdowns and their elimination
Start the car engine without usingelectric starter is very much possible. To do this, you need to either push the car well or ask someone to take you to the tugboat. But, you see, not always with you in the cabin there are passengers who would help to get the car with a "pusher", and not every counter-driver agrees to carry you.
Unfortunately, on domestic carsproduction problems with engine start occur everywhere. As far as the starter is concerned, it itself rarely fails. But the details that ensure his work, often fail.
In this article, we'll talk about what constitutesretractor starter relayand understand with its construction on the example of VAZ-2114. In addition, we will consider its problems, as well as possible malfunctions of other elements of the engine start system that have similar characteristics.
The design of the starting device and where on the VAZ-2114 there is a starter relay
The starter of the "fourteenth" is an ordinary DC motor consisting of:
- four-pole armature;
- bendix (overrunning clutch);
- retracting (traction) relay.
The case of the device is closed with two covers. In the design of the electric motor, he is assigned the role of a stator. Inside it is a four-pole armature (shaft with windings) rotating around its horizontal axis. The shaft is held by means of two support bearings located in the engine casing.
Bendix, or overrunning clutch is a mechanism that engages the gear of the armature with the crown of the crankshaft flywheel. It is located in front of the rotor.
Where on the VAZ-2114 is the starter relay? It is located directly on it. From above. In fact, this is not the usual device in our view, closing contacts. It performs two functions at once. It closes the contacts of the winding of the armature, and also sets in motion the bendix with the gear.
Retractor relay starter consists of:
- steel casing;
- ebonite body cover;
- retracting and holding the windings;
- rod with a spring and a contact disk.
With the ignition off, the anchor, thanksspring, is in the extended position. The gear wheel of the bendix is not engaged with the flywheel crown. When we turn the ignition key to the second position, the relay contacts are energized. The magnetic field created by the retracting coil actuates the armature. It moves back, compressing the spring, and closes the contacts through which the voltage goes to the starter. The retractor winding is switched off at this point, and the holding winding is turned on.
During the movement, the arm moves the plug through the shaftrotor. She, in turn, moves the bendicks, inserting the gear into engagement with the flywheel. When we release the ignition key, the voltage on the holding coil ceases to flow, and the armature returns to its original position under the influence of the spring. The fork, at the same time, disconnects the gear of the bendix and the crown of the flywheel.
Symptoms of a faulty retractor relay
The fault of the traction relay can be determined by the following symptoms:
- when the ignition is switched on, there is no characteristic click, accompanying the movement of the anchor device to the extreme rear position (the starter does not turn, the enginedoes not start);
- a click is heard, but the trigger does not work;
- the relay trips, the starter starts the motor, but does not turn off.
If you, having turned on the ignition, found thatthe engine does not start, and thus there is one of the listed signs of a malfunction of the starting device, try to find the problem yourself. In some cases, the breakdown may be on the surface, and to eliminate it, it will take only a few minutes.
No click of retractor relay
The absence of a click may indicate that,that either no voltage is applied to it, or problems with the retracting winding. First of all, we check the wiring. To do this, visually examine the positive wire going to the relay from the battery, and then the thin conductor from the ignition switch. If possible, check the voltage value with a voltmeter (multimeter) by attaching its positive probe to the terminal on the relay, the wire from which goes to the battery, and the negative to the "weight". The device should indicate the battery voltage. If this indicator is lower, you need to look for a problem in the posting.
If the voltage is applied to the relay, tryStart the engine directly, without the ignition switch. To do this, disconnect the wire from it and close the relay contacts (the lead to the battery and the output to the starter) with a screwdriver. It worked? Disassemble the ignition contact group.
There is a click, but the starter does not rotate
If you turn on the ignition, you clearly hearclick the relay, the problem is most likely in the starter itself. Perhaps, the brushes were worn, or there was a break in one of the windings. In any case, further diagnostics without dismantling the device is impossible. If there is a break in the windings, the starting device can be tried to restore, entrusting it to winding specialists for winding. If the situation with him is generally bad, it is better to buy a new starter 2114. The price for it varies between 3700-5000 rubles.
The relay trips, the starter starts the motor, but does not turn off
In this case, the problem should be sought either inwindings of the relay, or in its mechanics. A precise diagnosis of the device is possible only after its dismantling. The most common cause of such a failure is a spring, which by virtue of their "fatigue", unable to push the anchor to the forward position.
How to replace the retractor relay starter VAZ-2114
Now let's move on to the process of dismantling and replacingtraction relay "fourteenth". At once we will designate, that for this purpose it is better to remove the starter assembly. So it will be possible to check in parallel the condition of its brush assembly and bearings. So, the process of replacing the relay is as follows:
- Remove the negative terminal from the battery.
- We disconnect the wires from the relay terminals and from the output of the starter brush assembly.
- We unscrew bolts of fastening of a starter to a crankcase of coupling. We take it from the seat.
- We turn away coupling bolts of fastening of the relay.
- We disconnect the relay from the starter, install a new one in its place.
- Installation is carried out in the reverse order.
With that,where the VAZ-2114 is a starter relayand how to replace it, we sorted it out. But in the engine start system there is one more detail with a similar name. Yes, it is also called a "starter relay". Only additional. And his function is completely different.Additional starter relayserves to ensure the safety of the entire trigger mechanism. Without it, the brushes and armature windings would burn almost every time you started.
You again ask,where the VAZ-2114 is a starter relay? On the first models of the "fourteenth" itwas located in the engine compartment at the top on the partition separating the engine compartment and the cabin. On the new VAZ-2114 it is not there. And some "experts" with foam at the mouth prove that on cars of the family "Samara" -2 it is not provided at all.
In fact, there is an additional relay, hereonly located it under the steering column. It is enough to remove the bottom part of the plastic cover, and you will immediately see it. This is a conventional four-contact relay with the marking 98.3777-10, which protects the starter circuit. If you have problems with starting the power unit, do not be too lazy to check it.
