ELECTRICAL SYSTEM

The following chart is provided to help in diagnosing the probable source of troubles. It should be used

as a guideline. Some causes or corrections may not apply to a specific model.

Symptom:

STARTER DOES NOT TURN.

1. Check fuse.

- Burnt fuse. Check wiring condition and replace fuse.

2. Check continuity of starter switch contact points.

- Poor contact of starter switch contact points. Repair or replace switch.

3. Check continuity between starter switch and solenoid on fan-cooled models or between

starter switch and MPEM on liquid-cooled models.

- Open circuit. Repair.

4. On liquid-cooled models check continuity between MPEM and solenoid switch.

- Open circuit. Repair.

Symptom: STARTER TURNS BUT DOES NOT CRANK THE ENGINE.

1. Check engine.

- Engine seized. Rebuild engine.

2. Check wire connection.

- Inadequate connection (too much resistance). Clean and reconnect.

3. Check battery charge.

- Weak battery. Recharge battery and verify recharge system and wires.

4. Check battery capacity.

- Shorted battery cell(s). Replace.

5. Check starter relay contact disc.

- Burnt or poor contact of starter relay contact disc. Replace starter relay.

6. Check continuity of starter relay pull-in winding.

- Open circuit of starter relay pull-in winding. Replace starter relay.

7. Check continuity of starter relay hold-in winding.

- Open circuit of starter relay hold-in winding. Replace starter relay.

8. Check brushes.

- Poor contact of brushes or worn. Replace brushes.

9. Check commutator.

- Burnt commutator. Turn commutator on a lathe. Respect outer diameter wear limit. Refer to

ELECTRIC STARTER.

10. Check height of commutator mica.

- Commutator mica too high. Undercut mica.

11. Check field coil resistance.

- Shorted field coil. Repair or replace yoke.

12. Check armature resistance.

- Shorted armature. Repair or replace armature.
