Solenoid Pull-In, Hold-In & Return Test
WARNING:
Keep fingers and tools away from opening in starter drive housing while performing test. The strong shifting action of solenoid could cause personal injury or damage as drive pinion moves into cranking position and spins.
CAUTION:
DO NOT engage starter solenoid for longer 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. Disconnect starter-to-solenoid field lead terminal. See Fig 1. Ensure field lead does not touch starter housing. Connect a jumper wire from negative battery post to solenoid field lead terminal.
- Connect another jumper wire from negative battery post to starter drive housing. Connect another jumper wire from positive battery post to solenoid "S" terminal. 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 jumper wire from solenoid field lead terminal (hold-in test). If pinion gear remains extended, go to next step. If pinion gear does not remain extended, replace solenoid.
- Disconnect jumper wire from starter drive housing (return test). 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.
