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

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.

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

If necessary, replace the generator rotor assembly.

Check the resistance.

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)	3.4 to 3.8 Ω

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

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.

Using a vernier caliper, measure the slip ring diameter.

• 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.
