- Remove diode (rectifier) assembly from generator. Check continuity of each diode in both directions by reversing test probes between diode terminals. See Fig 1 . To test all 9 diodes, perform continuity checks between terminal "B" and each "P" terminal, terminal B1 and each "P" terminal, and terminal "E" and each "P" terminal.
- All diodes should show continuity in one direction and no continuity in the opposite direction. If any diode does not test as specified, replace diode (rectifier) assembly.
