Bench Testing: Diodes

  1. With diode/rectifier assembly removed and on bench, contact positive diode plate terminal with one ohmmeter probe. Using other ohmmeter probe, contact each of 3 diode leads in same plate. Note ohmmeter reading. Reverse ohmmeter probes, and repeat tests for all diodes.
  2. All diodes should show continuity in one direction and no continuity in opposite direction. If any diode is defective, replace diode/rectifier assembly.
