Starter Motor: Testing and Inspection
Starter Performance Test
1. Disconnect the wires from the S terminal and the M terminal.
2. Make the connections as shown using as heavy a wire as possible (preferably equivalent to the wire used for the vehicle). To avoid damaging the
starter, never leave the battery connected for more than 10 seconds.
3. Connect the battery as shown. Be sure to disconnect the starter motor wire from the solenoid. If the starter pinion pops out, it is working properly.
4. Disconnect the battery from the M terminal. If the pinion does not retract, the hold-in coil of the solenoid is working properly.
5. Disconnect the battery from the starter body. If the pinion retracts immediately, it is working properly.
6. Clamp the starter firmly in a vise.
