Checking the generator stator

The stator is checked separately, after disassembling the generator. Its winding leads must be disconnected from the rectifier valves.

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

The insulation of the winding wires must be free from overheating, which occurs during a short circuit in the valves of the rectifier unit. Replace a stator with such a damaged winding.

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