These connections were not present or working when I got this trailer, and I can't figure out a couple of puzzles. This shows what looks to be the original box, but this does not look like the set-up in a '72 service manual, which showed only 2 circuits. There was a switch located in the bathroom cabinet wired (the short piece of Romex) into the first circuit wire which looks like it was added later. What is this circuit/switch?
Also, while I was installing a new AC, I found some of those "Hmmm…" things. One was the complete absence of any insulation in the space between the old AC and the next cross-rib! I guess that's one way to justify installing air conditioning!
The installer had also used just a single piece of 2" aluminum scrap under the front of the AC between the skins to clamp the unit to its ceiling frame. How it held out any water at all is a mystery. But there was also this mess of wire just stuffed into the space where there should have been insulation - what are these wires for?
Any help would be greatly appreciated -
