Ok, yesterday my awitch stuck, so I pull the ground, put a new switch in and connected theground, all I get is a click. So today I move the batt cable from the first solenoi to the 2nd one so I can see which one was bad. I go to hook the groundup and all it does is spark? The car lifts and dumps so it's not the the motor thats giving a click. Why won't it connect without sparking?
