The middle wire on the battery terminal buss bar is getting hot when running. Additionally the car will suddenly die at low speed and sometines the key won't turn. Are the three related. We just got the car as a repo and the previous owner apparently had issues because the middle wire has been spliced about 8" from the termial box and it has a brand new battery. I am thinking it could be the ignition switch. Where can I find an electrical diagrahm
