See instructions provided by manufacturer of volt-ampere tester being used. 4. Install jumper wire from solenoid terminal to solenoid battery terminal. The starter motor should operate. If starter motor fails to operate, replace faulty starter motor assembly. 5. Adjust carbon pile load of tester to obtain free running test voltage. Refer to STARTER MOTOR SPECIFICATIONS for starter motor free running test voltage specifications. 6. Note reading on ammeter and compare reading to free running test maximum amperage draw. Refer to STARTER MOTOR SPECIFICATIONS for starter motor free running test maximum amperage draw 7. If ammeter reading exceeds maximum amperage draw specification, replace faulty starter motor assembly. STARTER SOLENOID Certain vehicles with certain engines may require starter motor removal for the following test. 1. If necessary, remove starter motor from vehicle.
