    *b Lock

    1. When rotating the pulley, check that it turns clockwise and it does not turn counterclockwise.

  2. INSPECT GENERATOR REGULATOR ASSEMBLY

    A01KEVDE01

    1. Using an ohmmeter, check the continuity between terminals F and B.

      Standard
      When the positive and negative poles between terminals F and B are exchanged, there is continuity in one way but no continuity in another way.

      If the continuity is not as specified, replace the regulator.

    2. A01KIO7E01

      Using an ohmmeter, check the continuity between terminals F and E.

      Standard
      When the positive and negative poles between terminals F and E are exchanged, there is continuity in one way but no continuity in another way.

      If the continuity is not as specified, replace the regulator.

  3. INSPECT GENERATOR ROTOR ASSEMBLY

    A01KELH

    1. Check the rotor for open circuit.


      1. Using an ohmmeter, check that there is continuity between the slip rings.

        Standard resistance
        2.1 - 2.5 at 20°C (68°F)

        If there is no continuity, replace the rotor.

    2. A01KFBN

      Check the rotor for ground.


      1. Using an ohmmeter, check that there is no continuity between the slip ring and rotor.

        If there is continuity, replace the rotor.

    3. A01KFHN

      Check that the slip rings are not rough or scored.

      If rough or scored, replace the rotor.

    4. Using vernier calipers, measure the slip ring diameter.

      Standard diameter
      14.2 - 14.4 mm (0.559 - 0.567 in.)
      Minimum diameter
      12.8 mm (0.504 in.)

      If the diameter is less than the minimum, replace the rotor.

  4. INSPECT RECTIFIER END FRAME

    A01KIJJ

    1. Check the stator for open circuit.


      1. Using an ohmmeter, check that there is continuity between the coil leads.

        If there is no continuity, replace the end frame.

    2. A01KIOZ

      Check the stator for ground.


      1. Using an ohmmeter, check that there is no continuity between the coil lead and drive end frame.

        If there is continuity, replace the end frame.

  5. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY

    *a Length

    1. Using vernier calipers, measure the exposed brush length.

      Standard exposed length
      9.5 - 11.5 mm (0.374 - 0.453 in.)
      Minimum exposed length
      1.5 mm (0.059 in.)

  6. INSPECT GENERATOR HOLDER W/RECTIFIER

    A01KIQDE06

    *1 Positive Terminal
    *2 Rectifier Terminal

    1. Check the positive (+) rectifier.


      1. Using an ohmmeter, connect one tester probe to the positive (+) terminal and the other to each rectifier terminal.

      2. Reverse the polarity of the tester probes and repeat step (1).

      3. Check that one shows continuity and the other shows no continuity.

        If the continuity is not as specified, replace the rectifier holder.

    2. A01KFOSE07

      *1 Negative Terminal

      Check the negative (-) rectifier.


      1. Using an ohmmeter, connect one tester probe to each negative (-) terminal and the other to each rectifier terminal.

      2. Reverse the polarity of the tester probes and repeat step (1).

      3. Check that one shows continuity and the other shows no continuity.

        If the continuity is not as specified, replace the rectifier holder.

  7. INSPECT ROTOR BEARING


    1. Check the bearing is not rough or worn.

      If necessary, replace the bearing.
