SOLVED: No power getting to the thermostat
SOLVED: It was a short somewhere between the blue wires at the furnace and the tstat. Refer to this post Hi All, 1997 Terry 30g RV with an Atwood 8531-III DCLP furnace and a Coleman 7300 air con...

Ok boys.. based on my previous tests, I decided to just snip the tstat connections and re-wire them temporarily (without going through the walls). The tstat has power now. The fan runs. I didn't test the heat because I actually need to install a new regulator for the gas lines (when it rains, it pours eh?). But I assume it will work when I actually have gas flowing again.
So now I just have to run the new wires behind the walls. The problem is with the old wire going to the thermostat (the brown wire which contains the smaller gauge red & white wires). It is totally stuck. I tried pulling on it from both ends and it just won't budge. I was hoping I could just tape the new wires to one end and pull them through, but nope.
So it's stuck and I don't know where exactly the wire travels behind the walls/ceiling. I only know that from the tstat, it goes up toward the ceiling. From there, I have no idea where it's going. I did notice that it only moves on the tstat end if I also push up on all the tstat wires.. it moves with them. So I'm guessing it goes to the ceiling plenum, but I don't think it's worth taking that apart. So hopefully I'll figure out a way to run it behind my cabinets then through the walls. Any advice on doing that would be greatly appreciated. But I'm happy I at least understand the wiring now.
