Voltage Drop Test
NOTE:
Make all voltmeter connections at component terminal rather than at cable or wire end.
- Verify battery condition. Battery voltage should be 12 volts or more. Load test battery at approximately one-half cold cranking amperage rating. See load tester manufacturer's instructions. If battery voltage is less than 12 volts or loaded battery voltage is less than 9.6 volts, service battery or charging system as necessary.
- Disconnect inertia fuel shutoff switch to disable fuel system. Connect remote starter switch between starter solenoid terminal "S" (Gray wire) and positive battery post. See Fig 1 .
- Connect positive voltmeter lead to positive battery post, and negative lead to solenoid terminal "M" (solenoid-to-motor connection).
- Engage remote starter switch. Voltmeter should indicate .8 volt or less. If voltmeter indicates more than .8 volt, go to next step. If voltmeter indicates .8 volt or less, go to STARTER GROUND CIRCUIT TEST .
- Move negative voltmeter lead to solenoid terminal "B". Engage remote starter switch. If voltmeter still indicates more than .8 volt at terminal "B", go to next step. If voltmeter indicates less than .8 volt, solenoid connections or contacts are bad. Clean solenoid terminals "B", "S" and "M". Repeat steps 2) through 5) . If voltmeter still indicates more than .8 volt at terminal "M" and less than .8 volt at terminal "B", solenoid contacts are bad. Replace starter motor. See STARTER MOTOR under REMOVAL & INSTALLATION.
- Clean cables and connections at solenoid and battery. If voltmeter still indicates more than .8 volt at terminal "B", replace battery cable.NOTE: To locate excessive voltage drop, move voltmeter negative lead toward battery, and check each connection point. When high voltmeter reading disappears, problem is between last connection point and previous connection point.
