All lights are 12 volt and work fine.

Doc, I got to tell you this is a head scratcher.

Since all the 12 volt lights work, but the other 12 volt items do not, you are going to have to go the extra mile. It is possible there are blown fuses that "look good" but are not.

It is also possible that a wire junction behind the power center has come apart.

I was hoping someone would say "check the hidden fuse in location???" as opposed to a poor wire connection, yuck! looks like more multimeter testing is in order. Thxs.

Ummm correct me if I'm wrong but isn't there a fuse right on the fan?
I didn't see where anyone posted about it.

Fan fuse checks out a-ok with the multimeter and the mark one eye ball test.

I just checked on my wfco converter on my sabre and when I pulled the fuse the only light that went out was the shower overhead light .
The fan and light outside of the shower stayed lit. Hmmmmm
So I pulked the bedroom fuse and the fan and main light went out. Ah ha.

I don't know if this will help but just thought I'd pass the info on.

Given this info maybe just maybe yours might be similar and there a loose connection in your bedroom light?

Thanks for the tip. I figure that the straight forward logic of fuse a to circuit a and fuse b to circuit b gets a little muddled in the rv world. Will check that and take a hard look at the batteries again as we'll and let you folks know. Thxs for the input, keep it coming if anything else comes to mind.

Backdoc, I think the fans are "daisy chained" ie parallel wired so that one set of leads is attached over and over. The trick is to figure the way the electrician wired them. Usually the first device is then connected to the next etc. The first device should be closest to the power center. If the device has a bad supply connection the remaining fixtures cannot receive power either. It can be the bath fan first, followed by the main vent, range vent etc. You need to pull down the first device for the power panel. Check for 12 volt power on the circuit you suspect then the unit you pull down. Continue till one fixture has power on its line but is not passed on. Normally with this equipment circuits are made with plastic wire nuts and easy to troubleshoot. They don't install fuses at random, junctions are very common however. Its much easier to have a "bad" connection with 12 VDC because of the lower energy level as compared AC circuits. Happy hunting!

Sounds about right. Will try the parallel check pattern this weekend. Thxs
