Starter Motor: Testing and Inspection

Starter Performance Test

K20A3 Engine

1. Disconnect the wire from the S 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. If the starter pinion moves out, it is working properly.




4. Disconnect the negative battery terminal from the body as shown. If the pinion retracts immediately, it is working properly.
5. Clamp the starter firmly in a vise.




6. Connect the starter to the battery as shown, and make sure the motor turns and keeps rotating.
7. If the electric current and motor speed meet the specifications when the battery voltage is at 11.5 V, the starter is working properly.

Specifications
Electric current: 80 A or less
Motor speed: 2,600 rpm or more

K20A2, K20Z1 Engines

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. Make sure you disconnect the starter motor wire from the solenoid. If the starter pinion moves out, it is working properly.




4. Disconnect the negative battery terminal from the M terminal as shown. If the pinion does not retract, the hold-in coil of the solenoid is working properly.




5. Disconnect the negative battery terminal from the body as shown. If the pinion retracts immediately, it is working property.
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 make sure the motor turns and keeps rotating.
9. If the electric current and motor speed meet the specifications when the battery voltage is at 11.5 V, the starter is working properly.

Specifications
Electric Current: 90 A or less
Motor Speed: 3,000 rpm or more
