So i'm kinda pondering on the situation i'm having with my boat. I started thinking I may have possibly got the wires switched around when hooking them up to the second battery. I unhooked them from the starting battery, and re-hooked them up to my dual purpose/trolling battery. My question is, I've got one wire thats alot bigger than the rest of the wires in there....its a black cable, but has a short red sleeve covering where the eyelet is crimped on. I'm just wondering which wire this would be? Would it be the power, or ground wire? It doesn't have a circuit breaker on the end or anything. It's about a 4-6 gauge wire. What do you guys think? Ground or Power?
