GENERATOR INSPECTION


  1. INSPECT GENERATOR WITH CLUTCH PULLEY


    1. A00O7CK

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

      *1 Length

      Using a vernier caliper, measure the brush length.

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

  3. INSPECT GENERATOR ROTOR ASSEMBLY


    1. A00O8NXE02

      Check that the generator rotor bearing is not rough or worn.

      If necessary, replace the generator rotor assembly.

    2. Check the generator rotor for an open circuit.

        *1 Slip Ring

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

        Standard Resistance
        except Dual Air Conditioning System:
        Tester Connection Condition Specified Condition
        Slip ring - Slip ring 20°C (68°F) 2.3 to 2.7 Ω
        for Dual Air Conditioning System:
        Tester Connection Condition Specified Condition
        Slip ring - Slip ring 20°C (68°F) 3.4 to 3.8 Ω

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

    3. Check if the generator rotor is grounded.

        *1 Slip Ring
        *2 Rotor Core

        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 MΩ or higher

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

      *1 Diameter

      Using a vernier caliper, measure the 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 the diameter is less than the minimum, replace the generator rotor assembly.
