Re: Trying another tack... Looking for the right boat near Vancouver, BC.
Any wiring can be a nightmare if not done properly. I was on a boat on which the previous owner had decided he needed a blower. So he got some dryer hose and a 12 volt fan which he hooked up to a positive and a ground with a switch. The end result was a short in the system that drained the batteries after a period of time sailing. We were unable to start the engine and had to sail into Port Renfrew where the good folks lent us a couple of battery chargers.
I saw some of that mess that came out of your boat.
