I have a problem with my anchor light not coming on when I turn on the anchor light switch, and could use some help.
Situation:
My navigation lights on my cruiser consist of the red and green bow lights, a white stern light, and a combination masthead light/white all around light. They are controlled by two lighted SPST switches with a ground terminal to provide power for the switch light. (The switches are lit when turned ON). One switch is for the nav lights, one is the anchor light. The nav lights work properly, including the front bulb on the masthead light. The anchor light should consist of the front and back bulbs on the masthead light, but only the rear bulb comes on with the anchor switch. When I turn both the nav light switch and anchor light switch on, all of the lights come on, so I know that all of the bulbs are OK. It seems to me it must be a wiring problem at the switches.
The masthead light has three wires:
A black (ground) wire which goes to the ground tab on the nav light switch.
A red power line to the front half of the masthead light, and goes to the switched side of the nav switch.
A grey power lead to the rear half of the masthead light, and it goes to the switched side of the anchor switch.
This wiring obviously is not correct, but I don't know how to fix it. It seems I might need a jumper wire and a diode in one of the lines so as not to backfeed the nav light switch.
I hope this makes sense. Does anyone have any suggestions?
Thanks.
