Table 2-1. Troubleshooting-Continued
Test or Inspection
Step 3. Check for eccentric
commutator (out of round) by disassembling starter (para 3-4 through 3-12) and checking
eccentricity (para 3-14g).
Repair commutator (para 3-15e), if possible, and assemble starter (para 3-16 through 3-25).
Step 4. Inspect field coils for shorts or grounds (para 3-14f).
If field coils are grounded, replace starter.
Step 5. If armature shows excessive brush arcing, disassemble starter (para 3-4 through 3-12) check armature for grounds or
shorts (para 3-14g).
Replace starter if armature is grounded.
7. Starter Drive Fails to Engage.
Step 1. Check operation of solenoid relay by placing a jumper across battery terminal and solenoid relay terminal. This
should cause the relay to operate.
If the relay does not operate, remove relay (para 3-5) and install new relay (para 3-25).
Step 2. Check to see if solenoid relay linkage is adjusted properly (para 3-25f).
If adjustment is incorrect, remove solenoid relay adjusting plug and adjust linkage (para 3-25f).
Step 3. Check for binding in shift lever or drive assembly by partially disassembling starter (para 3-5, 3-6 and 3-7). Inspect
lever (para 3-14i) and drive assembly (para 3-14d) for defective parts.
Replace defective parts and assemble starter (para 3-23, 3-24 and 3-25).
8. Starter Vibrates During Operation.
Check for worn or damaged bearings by disassembling starter (para 3-4 through 3-12), inspect bearings (para 3-14b, c, and
h ) .
Replace bearings if necessary and assemble starter (para 3-16 through 3-25).
9. Drive Assembly Pinion Will Not Override.
Check for defective drive by disassembling starter (para 3-4 through 3-12) and inspecting drive assembly.
Replace drive assembly, if necessary, and assemble starter (para 3-16 through 3-25).
