Free Running Test
- Place the starter motor in a vise equipped with soft jaws and connect a fully-charged 12-volt battery to starter motor as follows.
- Connect a test ammeter (150-ampere scale) and carbon pile rheostats shown is the illustration.
- Connect a voltmeter (15-volt scale) across starter motor.
- Rotate carbon pile to the off position.
- Connect the battery cable from battery's negative post to the starter motor body.
- Turn on the switch connected between S-terminal and B-terminal, and adjust by carbon pile until battery voltage shown on the voltmeter reads 11 volts.CAUTION: This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.
- Confirm that the maximum amperage is within the specifications and that the starter motor turns smoothly and freely.
