Rectifier Diode / Bridge: Testing and Inspection

1. Inspect the (+) heat sink by checking the continuity between the (+) heat sink and stator coil lead wire connection terminal using a tester. If there is a continuity at both, the diode is short circuited, so replace the rectifier.




2. Inspect the (-) heat sink by checking the continuity between the (-) heat sink and stator coil lead wire connection terminal using a tester.




3. Check the diode trio by connecting an ohmmeter to both ends of each diode and check the continuity of the three diodes.
