      *1 Free
      *2 Lock

      Hold the center of the generator with clutch pulley, and confirm that the outer ring turns counterclockwise and does not turn clockwise.

      If the result is not as specified, replace the generator with clutch pulley.

  2. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY


    1. A00DR6U

      Using a vernier caliper, measure the length of the exposed brushes.

      Standard exposed length
      9.5 to 11.5 mm (0.374 to 0.453 in.)
      Minimum exposed length
      4.5 mm (0.177 in.)

      If the exposed length is less than the minimum, replace the generator brush holder assembly.

  3. INSPECT GENERATOR ROTOR ASSEMBLY

      *1 Slip Ring

      Check the generator rotor for an open circuit.


      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        Slip ring - Slip ring 20°C (68°F) 2.3 to 2.7 Ω

        If the result is not as specified, replace the generator rotor assembly.

    2. A00DUL4E16

      *1 Slip Ring
      *2 Rotor

      Check the generator rotor for a short to ground.


      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        Slip ring - Rotor Always 10 MΩ or higher

        If the result is not as specified, replace the generator rotor assembly.

    3. A00DPRB

      Check that the generator rotor bearing is not rough or worn, and that it rotates smoothly.

      If the result is not as specified, replace the generator rotor assembly.

    4. A00DTY0

      Using a vernier caliper, measure the diameter of each slip ring.

      Standard diameter
      14.2 to 14.8 mm (0.559 to 0.583 in.)
      Minimum diameter
      14.0 mm (0.551 in.)

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

  4. INSPECT GENERATOR ROTOR BEARING


    1. A00DTIA

      Check that the generator rotor bearing is not rough or worn, and that it rotates smoothly.

      If the result is not as specified, replace the generator rotor bearing.
