Load Test

Conduct this test if the starter motor cranks Slowly and to compare the current to specifications.
1. Connect Rotunda Alternator, Regulator, Battery and Starter Tester (ARBST). Make sure that current is not flowing through ammeter and heavy-duty carbon pile rheostat portion of circuit (rheostat at maximum counterclockwise position).
2. Place transmission in NEUTRAL or PARK. Crank engine with ignition switch OFF and determine exact reading on voltmeter. This test is accomplished by disconnecting the connector S at starter solenoid and by connecting a remote-control starter switch from positive battery terminal to S-terminal of starter solenoid.

NOTE: Make sure ignition switch is in the OFF position and S-terminal connector has been removed so engine does not start.

3. Stop cranking engine. Reduce resistance of carbon pile until voltmeter indicates same reading as that obtained while starter motor cranked the engine. The ammeter will indicate starter current draw under load. Check this with value listed in specifications. Electrical Specifications
