No Load Test: Notes
The starter No Load Test will identify open or shorted windings and a possible rubbing starter motor armature or bent starter motor armature shaft.
- Connect a fully charged battery, an Alternator, Regulator, Battery and Starter Tester (ARBST), and a remote starter switch to the starter motor. Connect the remote starter switch between the battery positive (+) post and the starter motor S-terminal. Connect the starter motor B-terminal to the battery positive (+) post. Connect the ARBST positive (+) terminal and negative (-) terminal to the corresponding battery post. Make sure that the battery and starter motor are grounded.
- Engage the remote starter switch.
- The starter motor should eject the starter drive and run smoothly. If the starter motor does not run smoothly, install a new starter motor.
- While the starter motor is running, check the voltmeter and ammeter.
- The voltage should be greater than 11.0 volts and the amperage should be no more than 70 amps.
- If the voltage is lower than the 11.0 volts, or the amperage is higher than 70 amps, install a new starter motor.
WARNING:
Make sure that the starter motor is securely mounted on a bench because the starter motor may move or jump when it is energized.
