3. INSPECT GENERATOR DRIVE END FRAME
a. Check the stator coil for open circuits.
1. Using an ohmmeter, check the resistance between the coil leads.
Standard resistance: Below 1 ohm
If the result is not as specified, replace the generator assembly.
b. Inspect the stator for ground.
1. Using an ohmmeter, check the resistance between the coil lead and drive end frame.
Standard resistance: 10 kohms or higher
If the result is not as specified, replace the generator assembly.
c. Inspect the bearing.
1. Make sure that the bearing is not rough or worn.
If necessary, replace the generator assembly.
4. INSPECT GENERATOR HOLDER WITH RECTIFIER
a. Using an ohmmeter, check the continuity among terminals P1, P2, P3 and B, and among P1, P2, P3 and E.
Standard:
When the positive and negative poles among terminals P1, P2, P3 and B are exchanged, there is continuity in one direction but no continuity in
the other direction.
When the positive and negative poles among terminals P1, P2, P3 and E are exchanged, there is continuity in one direction but no continuity in
the other direction.
