Starter Load Test
- Connect test equipment as shown. See Fig 1. Be sure that no current is flowing through ammeter and heavy duty carbon pile rheostat portion of the circuit.
- Disconnect the "S" terminal connector from the starter relay and connect a remote control starter switch. Crank the engine and determine the exact voltmeter reading.
- Stop cranking the engine and reduce the resistance of the carbon pile until voltmeter indicates same reading as that obtained while starter cranked engine.
- The ammeter will now indicate starter current draw under load. Normal starter load current is 150-250 amps for 4" starters or 150-210 amps for 4 1/2" starters. If load test current is not within specified range, starter motor must be overhauled or replaced.
