Stator Checks
Grounds, connect a 110 volt test lamp or an Ohmmeter from any stator lead to stator frame. If test lamp lights or if Ohmmeter reads low, windings are grounded. Open Circuit, if lamp fails to light or if Ohmmeter reads high when successively connected between each pair of stator leads, the windings are open. Short Circuit, a short in stator windings is difficult to locate without special test equipment due to the low resistance of windings. However, if all other electrical checks are normal and generator fails to supply rated output, shorted stator windings are indicated, also look for heat discoloration on the windings.
