Revival of an old one!
OK so I decided to dig into this a little more... here's what I've learned so far:
-The wiring does not match what the owners manual would suggest
-I can't wait to do a shell off one day and fix this whole mess
-I think I *might* have found the problem.
After going through the breaker box one at a time and identifying which plugs are on each breaker, I found that the exterior plug seemed to be the only one in an entire 15 amp circuit. Curious, I pulled the plug cover off outside and noticed that it was not the only plug, since it had an exit wire. Moreover, the black lead was completely severed.
The manual would suggest that perhaps the univolt outlet may be downstream.
Regardless I'm not putting power back on until I get this fixed, but fingers crossed.
The problem I face now is that it seems that wire has chaffed on the interior skin where it exits the wall by the wheel well and goes to the external outlet. I'm unable to pull more wire for fear of damaging something further, so at the moment I'm unsure how to properly repair this connection without removing the interior skin (which would mean the bed, overhead bins, part of the kitchen etc)...
Looking for suggestions please?
