OK, here goes trying to explain what happened. We were at a car show and on the way home, We stopped to eat. The car was running fine. I come out and the car just clicked. Starter wont turn over. I have great lights and power windows work. We try a jump start nothing. One of the guys noticed when I hit the key the negative battery cable would jump. Like someone was moving it. CRAZY RIGHT? So I keep trying to start it Nothing just clicks. I then remember I have a battery safety switch on the car. I turn it off and back on and the car started. Do you think the switch was or is bad? I have never in my life seen a negative cable jump like it was alive before? Thanks ahead of time for help!
