GENERATOR INSPECTION

PROCEDURE


  1. INSPECT BRUSH


    1. A004KPXE02
      Text in Illustration
      *a Minimum length
      *b Standard length
      *c Mark of minimum length
      A004K5G Brush

      Using a vernier caliper, measure the brush length.

      Standard length
      22.5 mm (0.885 in)
      Minimum length
      5.0 mm (0.196 in)

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

  2. INSPECT GENERATOR COIL ASSEMBLY


    1. A004HDCE01
      Text in Illustration
      *a Lead wire

      Check the resistance.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 Always Below 1 Ω
        1 - 3
        2 - 3
        4 - 5
        4 - 6
        5 - 6

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

    2. A004I0NE02
      Text in Illustration
      *1 Stator core
      *a Lead wire

      Check the resistance.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        Stator core - Lead wire Always 10 kΩ or higher

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

  3. INSPECT GENERATOR ROTOR ASSEMBLY


    1. A004HT1E03
      Text in Illustration
      *1 Slip Ring

      Check the generator rotor assembly for open circuits.


      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) 2.0 to 2.4 Ω

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

    2. A004IAUE03
      Text in Illustration
      *1 Slip Ring
      *2 Rotor Core

      Check if the generator rotor assembly is grounded.


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

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

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

    3. Check the slip ring diameter.


      1. A004KSKE05
        Text in Illustration
        *a Diameter of Slip Ring

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

        Standard diameter
        22.7 mm (0.893 in.)
        Minimum diameter
        22.1 mm (0.870 in.)

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

  4. INSPECT GENERATOR HOLDER WITH RECTIFIER


    1. A004KARE02

      Check the resistance.


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

        Standard Resistance
        Tester Connection Condition Specified Condition
        P1, P2, P3, P4, P5, P6 - B

        P1, P2, P3, P4, P5, P6 (Tester positive)

        B (Tester negative)

        Below 1 Ω

        P1, P2, P3, P4, P5, P6 (Tester negative)

        B (Tester positive)

        10 kΩ or higher
        P1, P2, P3, P4, P5, P6 - E

        P1, P2, P3, P4, P5, P6 (Tester positive)

        E (Tester negative)

        10 kΩ or higher

        P1, P2, P3, P4, P5, P6 (Tester negative)

        E (Tester positive)

        Below 1 Ω

        If the result is not as specified, replace the generator holder with rectifier.
