I'm trying to follow the terms you're using but when you say you used the test light at the outlet, just to be clear, you're talking about the bulb outlet and not some cigarette lighter type of outlet?
What about the wires leading INTO the outlet? Do you get power from where those wires come in? Could be just a bad light fixture.
And I do have a wiring diagram for 2005 and newer highwalls. Schematic just has a pair of wires labeled "To Ceiling Lights". It has never been helpful at all.
There isn't a bulb outlet there, it's just a 12v plug (it's not a cigarette lighter outlet, it's like a mono headphone jack) to plug in the portable light/fan combo over the dinette. I pulled down the receptacle and checked for power at the back of the fixture.
There are 4 wires that run to the roof, one set up the front right post (black and white) and one set on the bathroom/dinette side running up the back left post by the bathroom (black/red and black/blue).
The black and white wires in the front right corner look to control the general roof lighting. When I unplug it, the ceiling lights go out.
It looks like the black/blue wire at the rear is for the switched bathroom light but I'm not sure about the black/red in this pair and if it's supposed to be hot or ground. Since the outlet I'm looking at is different, like the switched bathroom light ( ie it's not a light fixture, but a 12v outlet) I'm wondering if maybe it's supposed to be powered by the black/red wire. The wires at the outlet itself are black and white, so if the black/red wire is powering it ( or providing ground for that matter) it would need to switch over somewhere to a pure black wire. I haven't had a chance yet to do a continuity check on it.
My thought right now is that both the wires in the rear/left post (black/red, black/blue) are supposed to be hot. The white wire running up the front right post could provide the ground for all the roof fixtures. The black/blue wire is pulled to a separate switch for the bathroom light. I'm betting the black/red wire here is supposed to power that 12v outlet and it's broken somewhere....
