Starter Motor Pull-In, Hold-In and Pinion Return Testing

NOTE: Do not allow the solenoid pull-in current to flow for more than 15 seconds at a time. The windings can be damaged by overheating. Also the current draw readings will decrease as the windings heat up.




1. Remove the field coil lead wire (1) from the solenoid terminal.
2. Install the test leads from the battery to the starter motor assembly.
3. Ensure that the pinion extends quickly and completely to the energized position (pull-in test).




4. Disconnect the negative (-) lead from the starter-to-solenoid wire solenoid terminal.
5. Verify that the pinion remains completely in the energized position (hold-in test).




6. Disconnect the negative (-) lead from the drive housing.
7. Ensure that the pinion returns quickly and completely to the de-energized position (pinion return test).
8. If the pinion does not return to the de-energized position, the cause is most likely a faulty starter solenoid return spring. Replace the starter solenoid.
9. If any of the above tests are not satisfactory, replace the starter solenoid. Refer to Starter Motor Overhaul.

NOTE: Refer to Fastener Notice in Service Precautions.

10. Install the field coil lead wire to the solenoid terminal.

Tighten
Tighten the nut to 10 N.m (89 lb in).

11. Install the starter motor assembly to the vehicle.
12. Connect the negative (-) battery cable.

Tighten
Tighten the negative (-) battery cable to 15 N.m (11 lb ft).
