Rectifier Assembly Inspection
PROCEDURE

1. Check for continuity between the positive rectifier terminals and the stator coil output terminal. The ohmmeter should show continuity in one direction only. If continuity exists in both directions, a diode is broken down and the rectifier must be replaced.

2. Check for continuity between the negative rectifier terminals and the stator coil output terminal. The ohmmeter should show continuity in one direction only. If continuity exists in both directions, a diode is broken down and the rectifier must be replaced.

3. Using an ohmmeter, check for continuity between the terminals of each of the three diodes. The ohmmeter should show continuity in one direction only.
If continuity exists in both directions, a diode is broken down and the rectifier must be replaced.
