Navagation and aft light issue

[weirdo0521]

Ran into an unusual problem yesterday. The Nav and aft light are on the same switch. Usually you can turn on the nav (bow) and panel alone, or select the switch to use nav and stern light. Yesterday it was nav and panel or just stern light. Both went on, just not at teh same time. Any suggestions?

Sounds like a three position switch where one or more of the positions has corrosion or a drop of moisture in there. I'd try removing it and cleaning the contacts before anything else.

Removing that switch is a HUGE PITA in my opinion...I broke mine trying to get it out when I was installing my LEDs.

Well, you could try blowing some air into it and turning it off an on 50 times to see if it cleans up.
