2011 Z9 and it is a wiring mess. Anyone can give me a general idea of how it's supposed to be wired? Has 3 batteries for trolliing,which looks normal. Then there's a 31 series deep cycle with 4 small gauge wires both positive and negative that just disappear into a tube going toward the bow, can't find them with a continuity tester under the dash. Then a 24 series dual service battery 550 CCA for starter that also powers the switch on dash that turns on all the pumps and both depth finders ! Two separate fuse boxes under the dash that i haven't started trying to trace yet. It actually works but i know it's a matter of time before the 24 series battery dies out from running so many accessories.
