TROUBLE SHOOTING

Note. See STARTER - GENERAL TROUBLE SHOOTING article in GENERAL INFORMATION.

ARMATURE TEST

FIELD COIL TEST

Using ohmmeter, check for continuity between starter solenoid lead and field coil brush lead. If continuity does not exist, replace field frame. Using ohmmeter, check for continuity between field coil end and field frame. If continuity exists, repair or replace field frame.

SOLENOID TEST

1. Disconnect starter field coil lead from terminal "C". Connect battery to starter solenoid as indicated. (Scheme 2) Perform STEP 1. Clutch pinion gear should move outward. If clutch pinion gear does not move outward, replace starter solenoid. If clutch pinion gear moves outward, go to next step.
2. Leave battery connected. Disconnect jumper lead from terminal "C". Perform STEP 2. Clutch pinion gear should remain in outward position. If clutch pinion gear does not remain in outward position, replace starter solenoid. If clutch pinion gear remains in outward position, go to next step.
3. Disconnect jumper lead from starter housing. Perform STEP 3. Clutch pinion gear should move inward. If clutch pinion gear does not move inward, replace starter solenoid. If clutch pinion gear moves inward, starter solenoid is okay.

Scheme 2

NO-LOAD TEST

Connect battery and ammeter to starter as indicated. (Scheme 2) Perform STEP 4. Starter armature should rotate smoothly and steadily with pinion gear moving out. Amperage draw should be 100-Amps or less at 11.5 Volts.

IGNITION SWITCH TEST

Using ohmmeter, measure resistance between specified terminals. For resistance specifications, see IGNITION SWITCH CONNECTOR RESISTANCE . If the resistance is not as specified, replace switch.
