Starter Motor No-Load Test
CAUTION:
Keep fingers and tools away from the opening in starter drive housing while performing starter no-load test. The strong shifting action of solenoid could cause personal injury or damage as drive pinion moves into the cranking position and spins.
- Remove starter from vehicle. Connect an ammeter in series with battery and starter to measure starter motor current draw. Connect a jumper wire from negative battery post to starter motor housing. Connect another jumper wire from positive battery post to an ammeter, and from ammeter to starter solenoid positive battery terminal. See Fig 1 .
- Starter drive pinion should extend quickly and completely and starter motor should run smoothly. Read starter motor current draw on ammeter. If current draw is not as specified, repair or replace starter. See STARTER SPECIFICATIONS table under STARTER SPECIFICATIONS for current draw specification.
