Well I swaped a D15B vtec in my civic but for some reason when I go to put the battery studs back on, the hot stud arcs. My battery fuse blew and I replaced it but now it just arcs. Besides ripping a wire on the way down when we did the install, I can't think of anything else that could of happen. Can pluging in a sensor plug in the wrong place do this or can it be the starter or alternator? Well any insight will help. Thanks.
