This document details how to perform continuity and ground tests on an alternator's stator and diodes.
_ l CHARGING SYSTEM Alternator Stator Check Diode Check _ To test the starter or diode, you must separate Diode jar and them by unsoldering the connecting wures. Perform a continuity test using ohmmeter. CAUTION: Ohmmeter probes Used only as much heat as required to melt solder. Continuity V ~ _ Positive Negative Diodes Will be damaged by excessive heat.
