Re: Wiring question
yellow is now the accepted ground, black used to be the negative, green is bonding( all objects that touch sea water are bonded together), Red is still 12 Volts positive. I woouldn't assume anything on your boat, small boats and previous owners make any combination of wiring colors posible. Don't assume anyhting, check each wire with a volt/ohm meter before you go pluging power into it
