Im still trying to make sense of my new to me oday 25-and its electrical system. Ok so basically Ive got two batteries-one for starting the engine and one for everything else-regulated by four way switch.(1,2,both,off). Then I have a circuit panel that turns on my cabin lights, nav lights, deck lights, and auxilary (which turns on the depthfinder,vhf, and supposedly the stereo which I cant get to work). I was a little worried that I didnt have an anchor light switch but after reading a little realized that all I have to do is hang a lantern from somewhere and that is adequate for anchor light. Does anybody know what the deck lights switch is for. The cabin lights work, the running lights work minus the mastlight(not sure why), and the gadgets fed off the auxiliary work minus the radio(not sure why)..cant figure out what the deck lights do?
