INSPECT GENERATOR BRUSH HOLDER ASSEMBLY
| *1 | Length |
Using a vernier caliper, measure the brush length.
| Standard length |
|---|
| 9.5 mm to 11.5 mm (0.374 to 0.453 in.) |
| Minimum length |
|---|
| 4.5 mm (0.177 in.) |
If the length is less than the minimum, replace the brush holder assembly.
INSPECT GENERATOR ROTOR ASSEMBLY
Inspect that the bearing is not rough or worn.
If necessary, replace the generator rotor assembly.
| *1 | Slip Ring |
Check the rotor for an open circuit.
Measure the resistance according to the value(s) in the table below.

If the result is not as specified, replace the generator rotor assembly.
| *1 | Slip Ring |
| *2 | Rotor Core |
Check if the rotor is grounded.
Measure the resistance according to the value(s) in the table below.

If the result is not as specified, replace the generator rotor assembly.
Using a vernier caliper, 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.
