David and Fred,
While it's not expected for you to figure out why there's no apparent switch for your exterior under-step light, should you want to dig into it, I learned this from the plant today.
Fused DC circuits terminate behind the DC Fuse Panel. If the panel was pulled outward from the wall, there will be one fuse circuit with two white wires with a purple stripe. One of those wires feeds the tank monitor panel and the other feeds the step light.
Your dealers will be able to sort all of this out and add, if missing, switch for your step light.
If you'd rather tear into yourself, that's up to you. If I was tearing into mine, I'd probably do the following:
- Replace the bulb (if removed) to get the step light back on
- Pull the fuse panel from the wall
- Remove the fuse that feeds the two white/purple lines
- Check to see if step light went out - if not, continue pulling fuses (and replacing them as I go) until the light goes out
- With the correct white/purple feed line determined, and using a flashlight, look back into the wall to determine where that line goes (up or down). I'd pull switch panels (carefully) as needed to follow wire routing. If the wire goes down, I might pull the step-light off the frame and pull the wires and splices out the hole in the frame and using a helper, tug in both directions to see of the line appears to be continuous or not
In the end, if it appears my step light was hot-wired inadvertantly, then I'd add a switch in the switch panel area and mark it "Step Light".
Dave - if you don't figure yours out before Tampa, sounds like a project for the guys
I probably have a brown switch if needed.
