I've got no power to my CC. No lights, no radios, no bilge pump, no key switch no power period. I figure it has to be either the main ground for my accessarys or the main power supply. I do have power to the outboard just not to my CC. Anyway I have cleaned or replaced the ends to the main ground wire for the accessarys and put a new fuse holder in the main power supply line. I figure somewhere one of those two wires must have a break in it. I'm just going to run 2 new wires but was wondering what size wire to use? Would #10 be heavy enough? I'm running engine instruments, lighting, gps, radios, bilge and livewell pumps & horn.
