Starter Ground Circuit Test

NOTE: Make all voltmeter connections at component terminal rather than at cable or wire end.

Slow starter cranking condition can be caused by resistance in ground or return portion of cranking circuit. Check voltage drop in ground circuit as follows:
Disconnect coil wire from distributor cap. Connect remote starter switch between starter solenoid terminal "S" and positive battery terminal.
Using a digital voltmeter set at lowest voltage scale, connect positive voltmeter lead to starter housing, and negative lead to negative battery post.
Engage remote starter switch and observe voltmeter reading. Voltmeter should read .2 volt or less. If voltage drop is more than .2 volt, clean negative cable connections at battery and chassis. Also, clean engine ground cable connections at front cover and engine mount bracket.
If voltage drop is still excessive, 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 or not at all, remove and repair starter.
