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.

2. INSPECT GENERATOR ROTOR ASSEMBLY

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

If necessary, replace the generator rotor assembly.

(b) Check the generator rotor assembly for an open circuit.

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