Starter failure is a nuisance that "visits" the domestic VAZ 2106 not so rarely. However, before rushing to the store for a new part, it makes sense to inspect the old unit to determine the cause of its inoperability.
Slow cranking, frequent clicks of the solenoid relay, or complete silence in response to an attempt to start the engine can all be the cause of a malfunctioning starter. However, before removing this "spare part" from the car, you need to make sure that it is in it; those. all wiring to the starter motor is in good condition and the battery is well charged. If so, you can proceed to dismantle the part to check its functionality.
Removing the starter from the VAZ 2106
Remove the positive terminal from the battery. Disconnect the hose connecting the air filter housing and the carburetor, unscrew the 3 nuts securing the air filter cover, and then 4 nuts securing its housing (key to "8"). If there is a heat-insulating shield with a hose, then you will have to remove it too. In the next step, disconnect the connector connecting the solenoid relay and the car's wiring. Along the way, unscrew the nut from the starter that connects the main, power wire from the battery. Now it is necessary to unscrew 3 nuts of the starter fastening (spanner wrench to "13"), - one of them from below; it is more convenient to unscrew it under the machine, for which the latter can be put on a jack and stand. Next, move the starter back to the radiator, and then pull it out and lift it up.
Functional check
Clean the "spare part" from dirt, dust. Use a thick wire to connect the starter housing to the negative terminal of the storage battery. Take a thinner conductor and connect terminal "50" (solenoid relay) to the battery positive. At the moment of contact, a click should be heard: in this case, the drive gear will appear in the starter window. This indicates that the part is intact. If there is no click, then it is necessary to purchase a different retractor relay, which is much cheaper than buying a new starter. There is another option, when there is a click, but the gear does not jump out; this indicates a malfunction of the retractor mechanism. At home, without experience, it is unlikely that it will be possible to restore it - you will have to carry it to the workshop.
An ohmmeter is required for further verification. Remove the rear starter cover to access the brush assembly. You will see the ends of the windings attached to the brushes. Place one ohmmeter probe on the body of the part, and with the second, in turn, touch the contacts attached to the brushes. The readings of the device should be in the region of 10 kOhm. If this value is much less, then there is an interturn short circuit in the stator winding. If, on the contrary, the ohmmeter needle shows "infinity", then there is a break. In any case, you will have to buy a new starter.
