There’s a Red 1/2” diameter “Pilot” light above the power cord reel compartment. See picture. It’s been driving me nuts trying to figure out what a previous owner had done. Well today I chased wires and came to a conclusion.

First of all the light is burned out. There was four other lights just like it in a box in a closet so I got them out. 3 of them didn’t work either; however, one did. So I connected it and turned on the toggle switch inside the power cord reel compartment. The light came ON.

I removed the mattress in the master stateroom and removed the panel at the head of the bed to gain access to the area of water heater and power cord reel motor. The toggle switch wires were wired to the power cord reel controller Batt + and -.

The only conclusion I can come up with is a previous owner wired the switch and light so when the switch is ON, it means the Battery switch under the salon steps is either position 1, 2 or both. Maybe it was just a quick way to tell from the dock that the 12v battery system is on? Unfortunately there wasn’t a fuse inline with either the switch or light, meaning the only protection was from the 12v panel circuit breaker for the cable reel.

Another mystery solved!

I’ve not figured out how or what to do about it but I’m not crazy about the way it’s wired.

If you guys know of a purpose for this light or a modification to add using what s there please advise! Else I’ll probably remove the wires and plug the hole.
