Retractor relay. Details about him

Probably, every motorist has encountered the problem of a malfunction of the starter and retractor relay, when at the most necessary moment the car simply refuses to start. And if everything is in order with the electrical circuit, the battery is charged, there is only one thing left - to look for a breakdown in the starter and in its peripheral devices. One of them is the solenoid relay, which we will talk about today.

How can I tell if a given part is defective?

By the way, you can determine the breakdown of the retractor relay even before the starter is removed. To do this, the wizard recommends closing two contact nuts on the back of the device. This should be done with a metal object (for example, you can use any piece of wire). When closed, all voltage will be applied to the starter winding. The solenoid relay is not affected. In this case, the starter will work without the last part. This just speaks of its malfunction. Well, what ifthe device working in the first case will only click, which means that the cause of the breakdown should be sought in it. In this case, the solenoid relay will definitely be in good condition, and it should not be disassembled.

What can cause a breakdown?

One of the most common causes is material fatigue, i.e. wear. Also, the retractor relay may break due to burnt out contact plates that are inside it. And the last common cause is the burning of the winding. In all cases, repair and replacement of parts is mandatory (otherwise the car will never run).

How does the VAZ 2109-2110 starter solenoid switch change?

First you need to disconnect the terminals from the battery, since this spare part belongs to the list of electrical devices. Then you need to unscrew the nuts securing the heat-insulating shield. This shield also needs to be removed. To do this, you will need a special extension to reach the nuts that hold this part with the engine support bracket. The lower starter mounting bolt should be unscrewed from the bottom of the machine, after which all upper nuts must be dismantled.

So we got to the relay. But this work is not completed, since this spare part has not yet been removed. And in order to dismantle the solenoid relay, remove the connector from the output and unscrew the nuts near them. Next, you will need to remove the wire present on the starter. After that, using a socket wrench, unscrew the fastening nuts of the relay wire, and also remove all the bolts that secure ourstarter tool.

And the last thing we need to do is disassemble the relay. In order to get to the retractor, you need to disengage the drive armature and boldly remove the broken spare part. Installing spare parts in place is done in a similar way.

As you can see, despite the rather simple design of this part, it is quite difficult to remove and install it back. Therefore, if necessary, mark all dismantled spare parts and nuts, and also do not forget about the instruction manual for your VAZ.
