Rectifier Test

  1. Check for continuity between positive diode lead and positive heat sink. There should be continuity (about 7 ohms) from positive diode lead to heat sink, and no continuity with meter leads reversed. Repeat test for each positive diode. If meter readings are not as specified, replace rectifier assembly.
  2. Repeat test for negative diodes. Check for continuity between negative diode lead and negative heat sink. There should be continuity (about 7 ohms) from negative diode lead to heat sink, and no continuity with meter leads reversed. Repeat test for each negative diode. If meter readings are not as specified, replace rectifier assembly.
