Sorry for my lack of knowledge on electrical, but I am trying to figure out why my nav & dash gauge lights are not working. It appears that I am not getting power to the switch since the light on the 3-position switch fails to light when I push it up the to "on" position. I have power to the other 3-position switches (map lights, depth finder & docking lights) which all work properly. I am looking for a little help on where to start & what I need to do to start searching for my problem. Thanks.
