Sorry to be an electrical idiot.... but that's what I am, and I want to be certain of what I think I'm seeing: We're talking about a 300 amp fuse on the pos. cable, and a 150 amp fuse on the neg, correct? Then, following Mike & Jim's outlines, a 100 amp fuse on the alternator wire, along with running that wire through the continuous duty relay.... Am I straight on this?
300 amp on the starter cable and 150 on the alternator cable. not the neg cable
