Re: nav light not working
I looked at your schematic. Forget it...it is a
plan for dc wiring, not necessarily what you have. If you did have that, it would be working.<br />

<br /><br />If you have voltage on the downstream side of that 5amp fuse, and you do if your bow light works, your problem is likely with the switch
is it wired correctly? Is the switch itself functioning properly? It could be the wire as Vipzach mentioned, or corroded connections. If it were a short I would expect that 5-amp fuse to blow, so I wouldnt be looking for that, yet.<br /><br />Btw, I didnt see an anchor light on that schematic, only a stern light (white) and bow light (red/green). Not uncommon for the anchor light to be integrated into the stern light but it would require a double-throw switch designed to light the bow and stern on one throw and just the stern/anchor light on the other throw. If this is your setup, Id definitely be looking at the way that double-throw switch is wired.
