1993 Excella switch mystery

Just inside the door are three white plastic switches. One is labelled "Steps" and it works the step and courtesy lights just outside the door. The second is labeled "Flood", but there is no flood light anywhere on the outside of this unit. The third has no label. When I pulled the un-labelled switch open to check the wires, I found that the hot wire had shorted and melted thru and was no longer connected to the switch. One wire remained connected, can't tell where it goes from there. A third wire had also melted loose, and looks like it was doubled with the hot wire, but it tests 0 volt, while the one I referred to as hot shows 12 volts. I don't want to reconnect these wires until I know what they power and can make appropriate checks, etc.

So, does anyone know what the "Flood" and un-labelled switch might be for?

Our 1992 Classic Excella has the same three switches. Fortunately all of our work. They are:

Steps, Flood, and interior lights in the living area.

The interior lights in the living area are two double lights that are controlled by the interior switch. For any of those interior lights to work the wall switch must be on. These four lights are the same style lights that are in other parts of the trailer, so that means they have the same slide-style switch on the light fixture frame. So we can leave the wall switch on and then turn the lights on and off with the slide switches, or we can leave the slide switches on and turn the lights on and off with the wall switch. Leaving the slide switches on and controlling the lights with the wall switch provides an easy way to control the lights as you enter and exit the trailer.

Thanks for your reply. My light fixtures are as you describe yours, and they all work despite the fact that the unmarked wall switch is disabled. I'll have to check to see whether they were re-wired in some way.

Where is your flood light located? On mine, there is a bracket located about mid-way between front and rear that has what looks like a small, 4" diameter patch under it. I'm wondering whether this was where the light once was.

Thanks again,

Sounds like that is where the flood light should be.

It's at the same height as the awning brackets at front and back, and there's also evidence of a lower bracket that had been removed, so it could also be from an old awning bracket. Where is the flood light on your Excella?

I'll take down the ceiling lights and look for evidence of re-wiring there, maybe I can find what became of the wires that melted off the unmarked switch. My wiring diagram shows only a step light, but I'm betting my lights were once wired as Lucius described.
