Starter Load Test

1. Connect Rotunda Starting and Charging Tester tool No. 078-00005, or equivalent. Ensure current is not flowing through ammeter and heavy duty carbon pile rheostat portion of circuit (rheostat at maximum counterclockwise position).
2. Disconnect push on "S" terminal at starter relay, then connect remote control starter switch from positive battery terminal and "S" terminal of starter relay.
3. Place transmission in NEUTRAL or PARK (automatic transmission) or fully depress clutch pedal (manual transmission), then crank engine with ignition switch OFF. Record exact reading on voltmeter.
4. Stop cranking engine, then reduce resistance of carbon pile until voltmeter indicates same reading as that obtained while starter cranked the engine.
5. The ammeter will indicate starter current draw under normal load. Compare this value with value listed in electrical specifications.
