1995 blazer 4.3 4x4 was having trouble losing connection at the battery so i bought bew terminals and they worked great for about 3 weeks and all of the sudden last night it wouldnt start when my girlfriend went to leave work so i drove up there tightened negative side bolt and it started up. She got home and went to leave and same thing no start no ceank. I had her try to start as i wiggled wires on both sides and i just happened to look up and saw smoke coming from a wire coming off of a set of lugs on the drivers side up high on the fender. Any help before i dig into it tonight after work would be great! Thanks
