GENERATOR INSPECTION


  1. INSPECT GENERATOR WITH CLUTCH PULLEY


    1. A003I27E01

      Rotate the pulley and check that it turns counterclockwise and it does not turn clockwise.

  2. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY


    1. A003B4TE01

      Using vernier calipers, measure the brush length.

      Standard length
      10.5 mm (0.413 in.)
      Minimum length
      4.5 mm (0.177 in.)

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

  3. INSPECT GENERATOR ROTOR ASSEMBLY


    1. A003EQ8

      Inspect that the bearing is not rough or worn.

      If necessary, replace the rotor.

    2. A003BSNE01

      Check the rotor for open circuit.


      1. Using an ohmmeter, measure the resistance between the slip rings.

        Standard resistance
        2.3 to 2.7 Ω at 20°C (68°F)

        If the resistance is not within the standard range, replace the rotor.

    3. A003D0ME01

      Check the rotor for ground.


      1. Using an ohmmeter, measure the resistance between the slip ring and rotor.

        Standard resistance
        10 kΩ or higher

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

    4. A003HV3

      Using vernier calipers, measure each slip ring diameter.

      Standard diameter
      14.2 to 14.4 mm (0.559 to 0.567 in.)
      Minimum diameter
      14.0 mm (0.551 in.)

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