Does anyone have any wiring diagrams to help me trace the wiring for the Anchor light? The light was out when I purchased the boat and I was told that a new bulb had been installed but that did not work. I have cleaned sprayed the corrosion spots on the ground wire next to the compression post and cleaned all connections in the power station. My next stop is at the top of the mast and I really would like to eliminate all possibilities below first.
