THOR #17357
Mirage by Thor Electrical

I have a 2001 mirage by Thor 5th wheel and I am having two issues I canít figure out:
1) the two over head lights in one of my slide outs donít work. They worked when I first got it and the outlets all still operate but, not the lights. I have replaced bulbs and that does not do anything. Other troubleshooting ideas?

2) I have 3 switches near my door when you first enter the RV. The middle one controls the majority of my lights in the living area but the one on either side of that switch seems to have no function. Any idea what they might go to?

What controls the Minority? Some switches control lights that have switches on them. Scare lights outside? awning lights? Step lights? Storage Bay lights? My 5th wheel 2002 had a Scare light on the driver side I could not see.

Outlets are 120 volts. Lights are 12 volts. Are the non working light side by side? Lights are daisy chained. Pull them from the ceiling and see where you loose the power.

Welcome to the Forum. I donít know your coach but to follow up the other poster:


1. Since you are having issues with the ceiling lights in the slide I will assume they are 12vdc lights and not 120VAC since you said the slide outlets work fine. Check fuses that power lights......although usually more than one DC light fixture is connected to a single fuse. Any other DC lights not working?
The next simplest problem might be a bad ground connection at the light fixture ďifĒ the fixture is fed 12vdc with a single wire (from the light switch) and chassis ground provides a return path from the fixture or a short wire under a screw in the ceiling space located near and connected to, the fixture. On a movable slide, that may not be a preferred way to wire the light.
Next simplest is if the light on/off switch is still working correctly. Check if the corresponding light switch has 12vdc on it and if there is continuity through the switch when operated.
It may also be possible that one or both of the DC wires that feeds the dead lights has flexed over the years and possibly broken a conductor internal to the wire outer sheath (or totally) wherever they transition from the slide to the coach. Normally there would be slack in the wiring to allow for this kind of flexible movement. The DC wiring "might" following along the same path with the AC wiring from the coach into the slide space so check under the slide for where those wires may be run.


2. The other two switches may control an awning, outside light by the door or possibly be a lock out for the electric steps (keeps them out so they do not follow the door being opened and closed).

Thank you!! I will do some more checking on possible combinations of what the switches may go to that has a secondary on it.

I will check this.

Ok I will do some checking on this... thank you!!
