tC L4-2.4L (2AZ-FE) (2005)
1. Using an ohmmeter, measure the resistance between the slip rings.
Standard: 2.3 to 2.7 Ohms at 20°C (68°F)
If the result is not as specified, replace the generator rotor.
2. Using an ohmmeter, measure the resistance between the slip ring and rotor core.
Standard: 1 MOhms or higher
If the result is not as specified, replace the generator rotor.
b. Check the slip ring diameter.
1. Using vernier calipers, measure the slip ring diameter.
Standard: 14.2 to 14.4 mm (0.559 to 0.567 in.)
Minimum: 14.0 mm (0.551 in.)
If the slip ring diameter is less than minimum, replace the generator rotor.
c. Check the appearance.
1. Check that the bearing is not rough or worn.
If necessary, replace the generator rotor.
6. INSPECT GENERATOR DRIVE END FRAME BEARING
