Solenoid Pull-In, Hold-In & Return Test
CAUTION:
DO NOT allow solenoid pull-in current to flow for more than 15 seconds at a time during testing, or damage to coil winding may result due to overheating.
- Remove starter from vehicle. See STARTER under REMOVAL & INSTALLATION. Remove starter field lead wire from solenoid terminal. See Fig 1 . Ensure field lead does not touch starter housing.
- Connect one jumper wire from negative battery post to solenoid field lead terminal, and one to starter housing. Connect another jumper wire from positive battery post to solenoid terminal "S". See Fig 1 .
- Pinion gear should extend quickly and completely when solenoid is energized (pull-in test). If pinion gear operates as specified, go to next step. If pinion gear does not operate as specified, replace solenoid.
- Disconnect negative battery jumper wire from solenoid field lead terminal. Verify pinion gear remains completely extended in the energized position (hold-in test). If pinion gear does not remain extended, replace solenoid.
- Disconnect negative battery jumper wire from starter drive housing. If pinion returns quickly to de-energized position, go to STARTER NO-LOAD TEST . If pinion does not operate as specified, repair or replace solenoid and/or starter.
