#### Starter Circuit Troubleshooting (cont'd)

4-6

Starter Solenoid Test

6. Check the following items in the order listed until you find the open circuit.

- Check the BLK/WHT wire and connectors between the under-dash fuse/relay box and the ignition switch and between the under-dash fuse/relay box and the starter.
- Check the ignition switch, refer to the 2001 Civic Shop Manual (see page 22-131).

7. Check the engine speed while cranking the engine.

Is the engine speed above 100 rpm (min-1)?

YES - Go to step 8.

NO - Replace the starter, or remove and disassemble it and check for the following until you find the cause.

- Excessively worn starter brushes
- Open circuit in commutator brushes
- Dirty or damaged helical splines or drive gear
- Faulty drive gear clutch

8. Check the cranking voltage and current draw.

Is cranking voltage greater than or equal to 8.7 V and current draw less than or equal to 230 A?

YES - Go to step 9.

NO - Replace the starter, or remove and disassemble it and check for the following until you find the cause.

- Open circuit in starter armature commutator segments
- Starter armature dragging
- Shorted armature winding
- Excessive drag in engine

9. Remove the starter, and inspect its drive gear and the flywheel ring gear for damage. Replace any damaged parts.

1. Check the hold-in coil for continuity between the S terminal (A) and the armature housing (ground). There should be continuity.

- If there is continuity, go to step 2.
- If there is no continuity, replace the solenoid.

2. Check the pull-in coil for continuity between the S terminal (A) and M terminal (B). There should be continuity.

- If there is continuity, the solenoid is OK.
- If there is no continuity, replace the solenoid.
