DIAGNOSIS AND TESTING > STARTING SYSTEM > COMPONENT TEST(S)
Starter Motor - Positive Circuit Test
NOTE: Always make the multimeter connection at the component terminal rather than at the wiring end of the connector. Making a connection at the wiring end of the connector could result in false readings because the meter will not pick up a high resistance between the wiring connector and component.
1. Make sure the battery is fully charged. REFER to: BATTERY .
2. Perform a battery drain test. REFER to: Battery Drain Check .
3. Connect a remote starter switch between starter solenoid "S" terminal and the battery positive terminal.
