I just purchased this boat and it has a new rocker switch for the navigation lights. It works fine on "anchor" and when I switch to "navigation" the fuse blows. I don't have any wiring diagrams to see if the wires to the switch terminals are on the correct terminal. It has a 5 amp fuse. The bow light is new (3 pole) and the back light works fine on my Lund. Any suggestions on anything I can check before I take it to a Lowe dealer? Thanks. Bill
