Alternator: Testing and Inspection
INSPECTION
1. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY
a. Check the brush length.
1. Using a vernier caliper, measure the exposed brush length.
Specified brush length: 4.5 to 10.5 mm (0.177 to 0.413 in.)
If the exposed brush length is less than the minimum, replace the brush holder assembly.
2. INSPECT GENERATOR ROTOR ASSEMBLY
a. Check that the bearing is not rough or worn.
If necessary, replace the rotor assembly.
b. Check if the rotor has an open circuit.
1. Measure the resistance between the slip rings.
Resistance: 2.3 to 2.7 Ohms at 20 degrees C (68 degrees F)
If the result is not as specified, replace the generator rotor assembly.
