Rectifier Diodes

  1. With rectifier assembly on bench, contact diode plate with one probe and each of the 3 diode leads with other probe. Note ohmmeter reading. Reverse probes and repeat test. Check all diodes in this manner.
  2. All diodes should show a low reading in one direction and NO reading in opposite direction. If any rectifier diode is defective, replace rectifier assembly.
