Rectifier Diode / Bridge: Testing and Inspection

Positive Rectifier Test:

Positive Rectifier Test
Check for continuity between positive rectifier and stator coil lead connection terminal with a circuit tester. If there is continuity in both directions, diode is shorted. Replace rectifier assembly.

Negative Rectifier Test:

Negative Rectifier Test
Check for continuity between negative rectifier and stator coil lead connection terminal. If there is continuity in both direction, diode is shorted, and rectifier assembly must be replaced.
