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. If the starter pinion moves out, it is working properly.




3. Disconnect the negative battery terminal from the starter as shown. 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 starts 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
