- Remove rectifier assembly from generator. Connect one ohmmeter probe to either terminal screw. Connect other probe to each diode lead terminal in turn. Record resistance measurements.
- Transpose probes, then repeat test. All diodes should have low resistance (6-10 ohms) in one direction, and show no needle movement with ohmmeter probes transposed. Repeat test for other set of diodes, moving first probe to other terminal screw. If measurements are not as specified, replace rectifier.
