Good idea. I still have that shiny clean spot in my trunk from where the ground was mounted before. I'll hook up a jumper cable to that spot and the (- batt. terminal) and see if it works. I will have to wait till it gets warmer though, since its a sesonal problem (hot weather only). I thought a 2 ga. ground cable would be enough but hey this isnt the first or last time I was wrong. If this thread still exists in the next few months I'll report back.
