Ceiling lights stopped working

[JMF-THOR]

We have a Thor Siesta SJ24. Can anyone tell us where the 12v fuses are for the ceiling lights? All the other lights are working. The fuse box under the bed does not state any light fixtures. Is there another fuse box somewhere?
Thanks.

I think your coach is a Sprinter class which I know nothing much about but if you are looking for fuse assignments maybe this link will help.

Thanks. I think there's only one fuse for all the lights. So it wasn't the fuse causing the problem.

So you got it fixed? Care to share the solution in case someone else has a similar situation/coach? Glad you are seeing the light once again.

I'm afraid not. But my fix-it husband checked the voltage of that connection at the G8 box under the bed and checked the settings on the Firefly, both of which are good - so it may be as simple as one light is bad and perhaps they are connected in serial (like Christmas tree lights). Hoping that's the case otherwise it could become a difficult one to find. We will talk to Thor Monday. In the meanwhile there are other lights in the coach so its not stopping us from camping.

Hi, thanks for the update. Don't give up. Typically multiple ceiling lights are wired in parallel not series. It could be something as simple as a bad connection; bad ground; broken or loose wire/connector etc. If you suspect the Firefly control system, give Firefly tech support a call as I understand they are very helpful. Good hunting.

Update! We got a new upgraded Firefly Multiplexer today. Guess what ... when the new one was installed the ceiling lights magically started working. Yay!

Great news.......I guess Firefly shed some light on your problem after all. Thanks for updating the forum.
