Negative Rectifiers

Connect test lead clip to rectifier end housing. Touch exposed connection of each negative rectifier with test probe. Test specifications and results will be approximately the same as for positive case rectifiers, except meter will read on opposite side of scale.

NOTE: If a negative rectifier shows shorted condition, remove stator from rectifier end shield and retest. Stator winding could be grounded to stator laminations or rectifier end shield, indicating a shorted negative rectifier.
