Lincoln Mark VIII Corrosion May Form at Grounding Points Near Battery
Lincoln Mark VIII Problem
Visitor, 1998 Lincoln Mark VIII, 123,000 mi
entire car grounds out and everything goes dead when i try to crank it over, i move some wires near the main ground on the battery and everything comes back on. grease it up with WD40 and the problem goes away for a while. ????? i am thinking of re-wiring all the wires near the battery just to be safe. not really sure which one is causing the problem or shorting out when i try to start the car.
