Diode Assembly

  1. To check diode assembly, remove it from rear cover. Using ohmmeter, check each diode for continuity in one direction only.
  2. If resistance or continuity is shown in both directions, diode is bad. If any diodes are defective, replace complete rectifier assembly.
  3. Diode trio is good if all tests show continuity exists in one direction only. If continuity exists in both directions, replace diode trio.
