On my 2006 Damon Challenger 355, I have no 12v power to the front under tv cabinet light, the antennae power booster and to the 12v cigarette lighter located under the instrument panel, passenger side. I checked all the 15a fuses and checked the operation of all the 12v items in the motorhome. All fuses are good and everything works. Is there an inline fuse somewhere? Why don't I have power to the front light, antennae power booster and cigarette lighter?

Pull the plate for the booster. There will be a fuse there. Your sig lighter may be on the same circuit.

Might be another block of fuses somewhere.....maybe under the dash cover. Did they ever work? What happened just before they quit? Good hunting.

The light you are concerned about is the "DOME LIGHT" (Think of the dome light in your car) it's hooked to the dome light circuit

This is controlled by the dash light dimmer control in most vehicles... My Intruder included and I suspect yours as well

If it's a dual lamp set the switch in the center position (one bulb on) and then rotate the dash lamp dimmer control all the way to the DIM end IIRC, you should feel a stop (Detent) and when you push gently past it the light will come on. Same as the dome light in many cars.

Ditto wa8yxm -- my front lights stopped working suddenly, and after much trouble shooting it came down to the instrument-panel dimmer being moved off its detent "click" while dusting. And ditto to locate the under-dash fuse panel, lots of chassis related fuses there. Finally, it's unlikely but possible that there's a house circuit running through your under-hood battery control center - more fuses to check.

I re-read the other posts... The other circuits, however, are well.. Other circuits.

So, hopefully you now see the light

But television is another issue

The antenna power boster and the 12 volt outlet that's on the plate with the button, antenna connection and light are all one fuse (all one pair of wires in fact) it will be in your HOUSE fuse block in all likely hood

Damon motor homes can have 3 (or more) fuse blocks

1: House, you know where that is. Use a fuse tester if you need I can tell you how to make a unique one

2: Chassis.. On my rig it'd down by the parking brake pedal (left of driver, near floor, near wall)

3: Battery control center (Antenna may be here too) this is under the "hood" it's a black box with 3 very heavy wires on the bottom. Yours may vary ... Considerably in this case. Several circuits including steps and horn and such run through this box

There is also a posibility of other fuses and or panels elsewhere

I found a bad 15a fuse under the hood in a gang of 12v fuses. I replaced it and power was returned to the power booster and the cigarette lighter plug. The power was still out to the under tv light. I did find a 10a fuse in the slot of the underhood fuse block in a 7.5a location. This location seemed to be dead. The fuse checked as good. Using a trouble light, we chacked all the fuses and this 10a in the 7.5a location showed no power. We did check it with the ignition key in run position as well as in the off position. There was no power to this 10a location. Seems like this is an open circuit. I am wondering if this is the circuit for the under tv light. If thi is the circuit, I am wondering if the circuit somewhere is open along the wiring system. As stated, there is no power to this one light under the tv. Still looking for an answer. I might just tap the power wires leading to the booster.

Ok, now that you have everything else working

TRY THE DASH LIGHT INTENSITY CONTROL As noted above on my rig, and at least one other, the light under the TV is the "equivalent of the DOME LIGHT in a car so try that switch

This light was not keyed to the dash lights per my investigations. I did get a suggestion from Damon to just run a new powerline to this light. Damon suspects a broken wire somewhere in the system.
