Starter Motor Ground Circuit Test

A slow cranking condition can be caused by resistance in the ground or return portion of the cranking circuit. Check the voltage drop in the ground circuit as follows:

1. Disconnect inertia fuel shutoff switch to disable fuel pump. See COMPONENT LOCATIONS . Connect remote starter switch between starter solenoid terminal "S" (White/Pink wire) and positive battery post.
2. Connect positive voltmeter lead to starter housing, and negative lead to negative battery post. Engage remote starter switch while observing voltmeter. Voltmeter should indicate .2 volt or less. If voltmeter indicates more than .2 volt, clean negative cable connections at battery and engine.
3. If voltage drop is still more than .02 volt, repair or replace negative battery cable and/or engine ground cable as necessary. Repeat starter circuit test after repair to ensure problem has been corrected. If battery and cables test okay and starter motor still cranks slowly, replace starter.
