Feed Circuit Resistance

Before proceeding with this operation, review Starting System Test. The following operation will require a voltmeter, accurate to one tenth of a volt.

CAUTION: Before Performing any starter test, the Ignition and fuel Systems must be disabled.

1. To disable ignition and fuel systems disconnect the Automatic Shutdown Relay (ASD) in the Power Distribution Center (PDC).

Test Ground Circuit Resistance:

2. Check that all wiring harnesses and components properly connected. Connect negative lead of voltmeter to battery negative terminal, and positive lead to engine block near the battery cable attaching point. Rotate and hold the ignition switch in the START position. If voltage reads above 0.2 volt, clean or repair the poor contact at ground cable attaching points. If voltage reading is still above 0.2 volt after correcting poor contacts, replace ground cable.

Test Battery Positive Cable Resistance:

3. Connect the positive voltmeter lead to the battery positive terminal, and negative lead to battery positive cable terminal on starter solenoid. Rotate and hold the ignition switch in the START position. If voltage reads above 0.2 volt, clean or repair the poor contact at:
- Battery cable to solenoid connection
- Battery cable to remote terminal
- Battery cable to battery
If reading is still above 0.2 volt after correcting poor contacts, replace battery positive cable as necessary.
4. If resistance tests do not detect feed circuit failures, replace starter motor.
