Remove starter relay. See COMPONENT LOCATIONS. Check for continuity between starter relay terminals No. 1 and 2. (Scheme 5) Continuity should exist. If continuity does not exist, replace relay. Check for continuity between starter relay terminals No. 3 and 5. Continuity should not exist. If continuity exists, replace relay. Apply battery voltage across starter relay terminals No. 1 and 2. Check for continuity between starter relay terminals No. 3 and 5. Continuity should exist. If continuity does not exist, replace relay.

Measure resistance between specified terminals. For resistance specifications, see STARTER RELAY CONDITIONS. To identify starter relay terminal locations (Scheme 5)
| Ohmmeter Connection | Resistance |
|---|---|
| Terminals No. 3 & 5 With No Battery Voltage Applied Through Terminals No. 1 & 2 | 10,000 Ohms Or More |
| Terminal No. 3 & 5 With Battery Voltage Applied Through Terminals No. 1 & 2 | Less Than One Ohm |
STARTER RELAY CONDITIONS
- Using ohmmeter, check for continuity between all segments of commutator. If continuity does not exist, replace armature. Using ohmmeter, check for continuity between commutator and armature coil core. If continuity exists, replace armature.
- Inspect commutator for dirty or burnt surfaces. Repair as necessary using No. 400 sandpaper or a lathe. Place commutator on "V" blocks. Using a dial gauge, measure circle runout. See «STARTER SPECIFICATIONS»(ref-168649-S22542402542004111200000) . Repair as necessary using a lathe.
- Using a vernier caliper, measure commutator diameter. See «STARTER SPECIFICATIONS»(ref-168649-S22542402542004111200000) . If commutator diameter is less than minimum specification, replace armature.
- Ensure commutator mica undercut depth is clean and free of foreign materials. Smooth out edge. Measure commutator mica undercut depth. See «STARTER SPECIFICATIONS»(ref-168649-S22542402542004111200000) . If undercut depth is less than minimum specification, correct depth by using a hacksaw blade to remove mica from between segments.
- Inspect commutator for dirty or burnt surfaces. Repair as necessary using No. 400 sandpaper or a lathe.
- Using ohmmeter, measure resistance between all segments of commutator. Resistance should be below 1 ohm. If resistance is not as specified, replace armature.
- Using ohmmeter, measure resistance between commutator and armature coil core. Resistance should be 10 10 kilaohms or higher. If resistance is not as specified, replace armature.
- Place commutator on "V" blocks. Using a dial gauge, measure circle runout. See «STARTER SPECIFICATIONS»(ref-168649-S22542402542004111200000) . Repair using No. 400 sandpaper or replace armature.
- Using a vernier caliper, measure commutator diameter. See «STARTER SPECIFICATIONS»(ref-168649-S22542402542004111200000) . If commutator diameter is less than minimum specification, replace armature.
- Ensure commutator mica undercut depth is clean and free of foreign materials. Smooth out edge. Measure commutator mica undercut depth. See «STARTER SPECIFICATIONS»(ref-168649-S22542402542004111200000) . If undercut depth is less than minimum specification, correct depth by using a hacksaw blade to remove mica from between segments.
BRUSHES
- Using a vernier caliper, measure brush length. See «STARTER SPECIFICATIONS»(ref-168649-S22542402542004111200000) . If brush length is less than minimum specification, replace brush holder and field frame.
- Using a pull scale, note brush spring tension the instant the brush spring separates from brush. See «STARTER SPECIFICATIONS»(ref-168649-S22542402542004111200000) . If brush spring tension is less than minimum specification, replace brush springs.
