Last night while driving the camera came on showing the rear. I thought it was odd and I tried to turn it off but it would not. When I stopped and shut down, the back up lights and camera were on and would not go out. I had to disconnect the chassis batteries to turn it off. This morning, I went and reconnected the batteries and there was a minor arc as i attached a positive cable and then I heard a hum and clicking sound.

Any ideas?????
