STARTER GROUND CIRCUIT TEST:

     To test the starter ground circuit, connect one voltmeter lead to the ground post of the battery, and the other lead to a good ground on the starter motor. Operate the starter motor and note the voltage drop. Permissible voltage drop is 0.2 volt.

     To make the solenoid circuit resistance test, connect one lead to the insulated battery post and the other lead to the proper control circuit terminal on the solenoid. Again note the voltage drop with starting system under load. Permissible voltage drop is 0.2 volt.

     A higher than permissible voltage drop reading indicates at least one point of high resistance in the circuit. Separate detailed tests of each component and each connection in the circuit must be conducted. when the point of high resistance is located, the poor connection must be cleaned or tightened or the defective unit or cable must be repaired, as the case may be.
