Aloha,
I have a 9929C , just today, I lost power to my ceiling lights .

BUT it is just the middle of the trailer. This includes the bathroom and vanity area. couch area mid sections.
It is just odd. I have bedroom and kitchen and door lights working.

Any ideas where as I might start looking?

I pulled one of the light fixtures out of ceiling and the wiring and outlet are in decent shape with clean connections. it is just weird.
Im thankful its not the whole trailer...but....what comes next. Need to get ahead of this. Trailer is up for sale here soon!

It's probably just a blown fuse. My trailer has two fuse circuits for the lights.

- Jack

thanks Jack

I went through this last month, turned the lights on and they blinked then went off, but not all the lights, same as yours. If its not the fuses take a long wire and ground it to a known good ground and touch one of the lights thats not working and see if they all don't light up. Hi-lo had a funky way of dealing with the ground wires. I found my problem above the kitchen cabinets where they tied all the ground wires together and screwed then into the frame, just loosen the screw and retighten. Good Luck

Another place to check is the connectors where the upper and lower halves are connected...mine is in the bathroom...
