Diode Assemblies

Test diodes with tester before dismantling slip ring and end frame. DO NOT lay positive diode carrier on housing or a false reading will be obtained. Disconnect conductor from "D+" to exciter diodes at heat sink.
Unscrew spring and brush holder and remove from alternator. Unsolder stator lead and negative diode connections. Unscrew exciter diodes heat sink and remove together with positive diodes heat sink. Clean all components with trichlorethylene prior to further testing.
