bushrat Art, that's what I had in mind. Leave the positive breaker, just switch the polarity going to the cabin light circuit

The way I read it he was just going to reverse the two... so red is black and black is red..

You'd be laying a landmine for yourself. At some future date, you or someone else will assume that breaker, like all the other breakers, is in a positive line. ZZZT! in a shower of sparks wondering "Gee, how'd that happen?!" you'd remember it was the line you reversed.

Nah, this is not the place to make shortcuts. Unless those wiring runs were made with zip cord, they should be color coded for polarity, better to find the mistake and fix it.

merttan Is it me or no one recycles anything anymore... Teak accesories at discount marine stores have many recyclable surfaces... Buy a couple for 10bucks...
How much of a radio disturbance 0.1 amps is going to be comparing to 1-2 amp range standard light bulbs?
It doesn't have to be all teak btw, a decent solid wood from homedepot is like 10 bucks and enought to make 10 fittings... Good staining, some urethane, all set...
But of course, getting creative is something and buying and installing is another... They both have their ups and downs...
At least don't stop people creating alternative solutions for the problems on hand...

artbyjody Also visit Lighting places, Home Depot's etc... most of their lighting if uses halogen or led, can easily be retro-fitted to a DC system quite easily. Usually the only change is the bulb. I have a selection of them I have been testing out, mainly because I hate the marine decor look to stuff you find in chandelieries. Sometimes, you also have to be a bit creative with mounting as well - but point is you are not really limited, and 12-30 bucks at Home Depot, a <$10 LED bulb, and a few hours to make it fit... can sometimes be even more a reward...
