Clean the ground connections on your car. Most important: Negative cable on the battery, ground point for the starter under the coolant bottle (on chassis), and the front connection point (remove the brake master cylinder access panel to reach). Had the exact same promblem that you have. Cleaned the ground conections and it was like installing a new alternator! I just removed the bolts and cleaned the bolts, nuts, chasiss metal, and the harness connection with foamy engine brite. Quick, easy, and didn't damage the epoxy. Start from there and work you way down to the lesser ground points. -Robert vin 6585 --- In dmcnews@xxxxxxxxxxx, Joe Palatinus <jpalatinus@xxxx> wrote: > Great, now my other D' is giving me a voltage problem.
