Sometimes it happens that the car does not want to start. This situation is familiar to many car owners. And, unfortunately, it often happens in the most uncomfortable and inappropriate moment. Of course, you need to do something. If the car's power grid is in order, and the battery is charged, then the problem can be in the starter. It is possible that a defective starter relay is defective. In this case, without repairs can not do. About this further in the article.

Retractor starter relay, device

The traction starter relay is located above the starter and firmly connected to it.

Basic relay parts:

• Contacts.
• Return spring.
• Magnet with windings: holding and retracting.
• Anchor.
• Frame.

WORK SCHEME OF THE INSTALLING RELAX STARTER VAZ

The restraint of the relay is always connected directly to the battery, and the retractive winding is connected to the "minus" through the starter. When the core of the traction relay presses the bolts of the workshop, and the starter comes to the starter from the battery, the similar "plus" enters and on the output of the "minus" of the retracting winding, as a result of which it turns off, and the current continues to go only by holding the winding, Which is weaker than retracting, but has enough power to constantly keep the core inside the case, which ensures the continuous operation of the engine. The use of two windings makes it possible to significantly save the battery energy when starting the power unit.

Signs of malfunction of the retractor relay VAZ

The external signs of malfunction of the retractor relay include such aspects:

• After launching the power unit, the starter continues rotation at high speed. This can be determined by rumor for severe buzz.
• After turning the key, nothing happens, the engine does not start or starts after several attempts.

Causes of the breakdown of the retractor starter relay

The causes of the starter breakage is somewhat:

• Short closure in holding or retracting winding.
• Weakening or deformation of the return spring.
• Stopping or breaking the holding or retracting winding.
• Burning contact plates inside the relay, "sticking" or a decrease in their contact area.

Varieties of retractor starter relays

Ravating relays that are used on VAZ cars are divided into four types:

• For non-defectory starters VAZ 2101-2107.
• For non-defectory starters VAZ 2108-21099.
• For reducer starters AZD VAZ 2113-2115, 2108-21099.
• For gear starters of all models of cars VAZ.

In addition, they are divided into unintended and collapsible. Collapsible - these are older models. Old and new are interchangeable.

What kind of relay is subject to repair

Repair is subject to only collapsible relays. Inspection devices when breakdown change assembly.

How to check the retractive starter relay VAZ

Relay checks are several:

• The restriction of the relay is determined quite simply - when starting, a click is distributed, which is made by a moving core. This fact indicates the serviceability of the device. If there is no click, then the relay does not work. If the relay clicks, but the starter does not twist, the possible reason for this is the burning of the relay contacts.
  
• If the relay is triggered, however, it is heard a kind of rattling, which means one or both of the relay winding is defective. In this case, the relay check is performed using an ohmmeter by measuring the resistance in its windings. Remove the return spring and core from the body, after which it in pairwise check the resistance between the "mass" and windings. This value should vary in the range of 1..3 Ohm. Then insert the core without a spring, close the power contacts and measure the resistance between them. This value should be within 3 ... 5 ohms, it depends on a specific relay. If the value is lower than the specified numbers, you can talk about the failure of the windings and a short circuit in the chain.

Tools, fixtures, consumables

To repair the collapsible retractor relay, you will need such tools:

1. Rosin.
2. Tin.
3. Soldering iron.
4. Flat screwdriver.

How to make repairs of the retractor VAZ starter relay (step by step)

Order of work:

1. Remove the housing cover mounting screws.
   
2. Next, you need to disappear ends of the winding.
3. Remove the lid to open access to the search for the likely problem - power contacts that can be burnt or worn out: In the first case, you can solve the problem with a grinding skin, and in the second it will help the replacement of contacts.
   
4. Now collect the relay and check it with its performance.
