Rectifier Diode / Bridge: Testing and Inspection

INSPECT RECTIFIERS (RECTIFIER HOLDER)
a. Check the positive (+) rectifier.
1. Using an ohmmeter, connect one tester probe to the positive (+) terminal and the other to each rectifier terminal.
2. Reverse the polarity of the tester probes and repeat step (a).
3. Check that one shows continuity and the other shows no continuity.

If continuity is not as specified, replace the rectifier holder.




b. Check the negative (-) rectifier.
1. Using an ohmmeter, connect one tester probe to each negative (-) terminal and the other to each rectifier terminal.
2. Reverse the polarity of the tester probes and repeat step (a).
3. Check that one shows continuity and the other shows no continuity.

If continuity is not as specified, replace the rectifier holder.
