Checking the generator stator (VAZ-21051)

The stator is checked separately, after disassembling the generator. The terminals of its winding must be disconnected from the rectifier unit.

1. First of all, check with an ohmmeter or with a test lamp and a battery to see if there are any breaks in the stator winding and if its turns are shorted to ground.

2. The insulation of the winding wires must be free of overheating, which occurs when there is a short circuit in the rectifier block diodes. Replace the stator with such a damaged winding.

3. Finally, it is necessary to check with a special flaw detector whether there are any short-circuited turns in the stator winding.
