Generators & Regulators: Overhaul Isuzu Oasis I

DIODE ASSEMBLY

1. Remove diode (rectifier) assembly from generator. Check for continuity in both directions by reversing test probes between terminal "B" and terminals P(1), P(2), P(3) and P(4). Check for continuity in both directions between diode terminal "E" (ground) and terminals P(1), P(2), P(3) and P(4). (Scheme 3)
2. All diodes should show continuity in one direction and no continuity in opposite direction. If any diode does not test as specified, replace entire diode (rectifier) assembly.
