Starter Motor: Testing and Inspection

Starter Performance Test




1. Make a connection for this test using the thickest (gauge) wire possible (preferably the same gauge as used on the vehicle).

NOTE: To avoid damaging the starter, never leave the battery connected for more than 10 seconds.

2. Connect the battery as shown. If the starter pinion moves out, it is working properly.




3. Disconnect the battery from the body. If the pinion retracts immediately, it is working properly.
4. Firmly clamp the starter in a vise.




5. Connect the starter to the battery as shown, and check that the motor turns and keeps rotating.
6. If the electric current meets the specification when the battery voltage is at 11.5 V, the starter is working properly.

Specification:
Electric Current: 80 A or less
