Not sure what these are called but I have some 12 volt circuit breaker fuses on a couple of circuits in the coach. The problem I am having is when I leave the lights in the bathroom area on for an extended amount of time they begin flickering and then go out. after I turn off the lights for a while all come on as normal. Is this normal? Can I replace the metal fuses with regular fuses?

What type of lights are they? If they are florescent you could have some bad bulbs or a ballast. If you have incandescent it could be a loose connection with the bulb, and if you have LEDs it could be a loose wire. It could also be a loose wire on the fixture or switch for all of the above. I think I'd start looking at the fixture and work back from there instead of going to the fuse box and starting.
Good Luck

Thank you for your timely response. Checked the fixtures and sure enough one of the fluorescent bulbs wasn't turned all the way to lock position. Turned it and I am pretty sure that fixed it. The fan in the bathroom used to change speeds a little when the lights came on and now it does not. I will sheepishly crawl back into my hole until I need more help. Thanks again.

I'm happy to see you found the fix!

I have a question about your original post:
What is a "12 volt circuit breaker fuse" or a "metal fuse"? ....(can you please post a pic of, or a link to, what you were talking about)?

Thanks

There has been some problems with the 12 volt breaker fuse box and the fix is a new metal one I think at a cost of about $300 an I think Kevin Waite (Former Country Coach Service Tech. & Owner) has them and the metal fuses are a relay fuse and I would not change them out. I am having the same problem but with mine the 30A fuse is a little loose in the fitting and that section will go out and I just tap on it and it comes back on. I have changed out all 27 light to LEDs.

When they get hot they trip and as soon as they cool they come back on. I have taken them out hot [using pliers] and put a cool wet cloth on them and put them back in and they work. They are located in the fuse box below the electrical panel.

That worked and I got the other one to work but that one does not have the same posts as mine, more like this one but in a metal cover.

That link worked for me.
That's what I assumed you meant but I wasn't sure.
Thank you.

You're welcome. I have always found that with electrical issues it's best to start at one end and work back. The trick is figuring out which end to start at. If you still feel sheepish go ahead and send me a 30 lb box of $100 bills and you will not longer feel sheepish and will come out of your hole.
