Starter Motor No-Load Test

CAUTION: Keep fingers and tools away from the opening in the starter drive housing while performing the Starter No Load Test. The strong shifting action of the solenoid could cause personal injury or damage as the drive pinion moves into the cranking position and spins.




1. Remove the starter motor from the vehicle.
2. Connect test leads from the battery and the ammeter (3) to the starter motor. The pinion should extend quickly and completely and the starter motor should run smoothly.
3. Measure the starter motor current draw. The starter motor current draw at 11 volts is 90 amperes. Refer to Starter Motor Usage.
