Starter Performance Test

1.Disconnect the wire from the M terminal.

2.Make a connection 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. Make sure you disconnect the starter motor wire from the solenoid. If the starter pinion moves 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.

7.Reconnect the wire to the M terminal.

8.Connect the starter to the battery as shown in the diagram, and check that the motor turns and keeps rotating.

 

9.If the electric current and motor speed meet the specifications when the battery voltage is at least 11 V, the starter is working properly.

Specifications 
Electric Current: 145 A or less 
Motor Speed: 3,300 rpm (min-1) or more
