Breaker label illumination

[SilverSailor]

This is one for the factory folks or a knowledgeable RTer. I have a 2015 R31-S and the cabin overhead lights are great, but there are times they are too bright. While installing a dimmer for these cabin overhead lights it was necessary to remove the 12VDC breaker panel. While it was open I noticed that all of the labels for the 12VDC breakers were wired in a daisy chain fashion, both the 12VDC side and ground. It looked like all the wiring was already in place to illuminate these labels. There is even a gray wire with a red marker, if memory serves me??, that looks like it should feed this daisy chain 12VDC, but I can't trace it to it's source. I did jumper the daisy chain 12 volt connection to 12 volts and sure enough all breaker labels illuminated. So... my question is: where does this daisy chain 12VDC feed from - where does the gray with red wire originate?? I've tried everything I can think of. I'm planning on using one of the spare breakers to operate the illumination of these labels.

on my 25 sc they lite up when nav lites are on

Also true for my 2012 R-27. But only when the nav lights are on. Not when the anchor light is on. I would think it should be "easy" item to arrange, but I haven't really dug into it. It might be tricky... possibly backfeeding voltage to the nav lights????

The idea of using a spare breaker to power the lights is pretty cool, however.
Keep us posted on what you find out.

This is correct. We wire these to the nav light switch.

Thank you,

Thanks all for the replies. After submitting the original post I remembered the R31 electrical schematics that Andrew has posted. Sure enough these verified what you guys posted in responses. I'm going to disconnect the lead (grey with red marker) from the Nav lights and label it for the future and heat shrink it to keep it "safe". I'm going to add a jumper from one of the Accessory breakers so I can switch the illumination off when we'll be away from the boat for awhile, but leave it on when we're aboard. Old eyes need the extra visibility provided by the illumination. :ugeek:
