Bench Testing: Diodes

WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2000 Toyota Tundra, 2000 Toyota Tacoma, 2000 Toyota Sienna, 2000 Toyota RAV4, and 2000 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.
  1. With diode/rectifier assembly removed and on bench, contact positive diode plate terminal with one ohmmeter probe. Using other ohmmeter probe, contact each diode lead 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.
