b. Using SST, remove the coil assembly.
SST 09950-40011 (09951-04020, 09952-04010, 09953-04020, 09954-04010, 09955-04071, 09957-04010, 09958-04011)
c. Remove the generator washer.
5. REMOVE GENERATOR ROTOR ASSY
6. INSPECT GENERATOR ROTOR ASSY
a. Check the rotor for open circuit.
1. Using an ohmmeter, check that there is continuity between the slip rings.
Standard resistance: 2.3 - 2.7 ohm at 20 °C (68 °F)
If there is no continuity, replace the rotor.
b. Check the rotor for ground.
1. Using an ohmmeter, check that there is no continuity between the slip ring and rotor.
If there is continuity, replace the rotor.
c. Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
