1. Generator drive belt loose or worn.
2. Battery cables loose, corroded or worn.
3. Fuse blown.
4. Fusible link blown.
5. Electronic voltage regulator or generator faulty.
6. Wiring fault.

1. Adjust tension or replace generator drive belt.
2. Repair or replace cables.
3. Check fuses.
4. Replace fusible link.
5. Test generator.
6. Repair wiring.

1. Generator drive belt loose or worn.
2. Wiring connections loose or open circuit.
3. Fusible link blown.
4. Warning indicator and pre-excitation resistor faulty.
5. Poor ground.
6. Electronic voltage regulator or generator faulty.
7. Battery.

1. Adjust tension or replace generator drive belt.
2. Tighten loose connections or repair wiring.
3. Replace fusible link.
4. Replace light, resistor or related components as necessary.
5. Repair ground.
6. Test generator.
7. Replace battery.

1. Electronic voltage regulator faulty.
2. Voltage sensing wire faulty.

1. Replace voltage regulator.
2. Repair wiring.

BRUSHES

1. Replace brushes if worn to limit. (Scheme 17) Replace all brush springs if any springs are damaged or corroded.
2. To remove brushes from holder, unsolder pigtail from terminal. (Scheme 18) To replace, install brush into the brush holder and solder lead wire.

ROTOR

1. Measure resistance between rotor slip rings. (Scheme 19) Resistance should be 3.1 ohms. If resistance is as specified, go to next step. If resistance is extremely low or high, replace rotor assembly.
2. Check continuity between each slip ring and rotor core. (Scheme 20) There should be no continuity between either slip ring and rotor core. If continuity exists, rotor is shorted internally. Replace rotor assembly.

Scheme 20

STATOR

1. Check continuity between stator coil leads. (Scheme 21) If continuity exists, go to next step. If continuity does not exist, replace stator assembly.
2. Check continuity between each stator coil lead and stator core. (Scheme 22) There should be no continuity between any stator coil lead and stator core. If continuity exists, replace stator assembly.
