Starter Feed Circuit Resistance Test

The following test will require a voltmeter accurate to 1/10 volt.

1. With wiring harnesses and components connected properly, proceed as follows:
a. Connect positive lead of voltmeter to negative battery post and negative lead to negative battery cable clamp. Turn ignition switch to Start position and observe voltmeter. If voltage is detected, correct poor contact between cable clamp and post.
b. Connect positive lead of voltmeter to negative battery terminal and negative lead to engine block near battery cable attaching point. Turn ignition switch to Start position and observe voltmeter. If voltage reads above .2 volts, correct poor connection at ground cable attaching point. If voltmeter still reads above .2 volts after correcting poor contacts, replace ground cable.

2. Remove starter heat shield, then proceed as follows:
a. Connect positive voltmeter lead to starter motor housing and negative lead to negative battery terminal. Turn ignition switch to Start position. If voltage reads above .2 volts, correct poor starter to engine ground.
b. Connect positive voltmeter lead to positive battery terminal and negative lead to battery cable terminal on starter solenoid. Turn ignition switch to Start position. If voltage reads above .2 volts, correct poor contact at battery cable solenoid connection. If reading is still above .2 volts after correcting contact points, replace positive battery cable.

3. If resistance tests detect no feed circuit failures, remove starter motor and perform tests under "Bench Tests.
