Diode Assembly

  1. Place ohmmeter on X100 scale. Connect ohmmeter leads, in turn, between B+ terminal and each of the 3 stator terminals. Refer to Fig 1. Reverse leads. Ohmmeter should indicate continuity in one direction only.
  2. Connect ohmmeter leads, in turn, between negative plate and each of the 3 stator terminals. Reverse leads. Ohmmeter should indicate continuity in one direction only.
  3. Connect ohmmeter leads, in turn, between D+ terminal and each of the 3 stator terminals. Reverse leads. Ohmmeter should indicate continuity in one direction only. Replace diode assembly if continuity is not as specified.
