I agree that that may be the problem. I have heard similar tales of woe
through the years. I run about 4 ground straps between the
engine/frame/body. Overkill? Maybe but it doesn't cost anything. Of course
there are numerous other ground straps throughout my car in addition to the
ones I mentioned. Cheap Insurance.
