Thanks for everyone's help. On the advice of @fr8trplt I posted this over at the Tiffin RV Forum and got several really good ideas on where to look.
It actually really makes sense now in retrospect. There is a fuse box upstream from the solenoids that are controlled by the Emergency Start Switch on the ignition battery side. This morning I found a blown fuse in that box. So the DC was not getting from the Ignition battery to the system, and when I pressed the E-Start switch, the house batteries were being dropped in parallel, which would power the camera, windows and jacks.
Even though it totally makes sense now, I definitely would not have figured this one out on my own.
Thanks again for everybody's help!
I recently had a weird electrical issue that I've tracked as far as I can on my own.
I was driving the MH and everything was working fine. I had some trouble cranking up the generator and through the process of getting it started, I lost the back-up camera, power windows, and the annoying alarm that goes off when the jacks are down. While messing around trying to find the problem, I noticed that the above mentioned systems came back on-line when I held down the Emergency Start Switch button.
It seems like something has gotten out of sequence with the solenoid, like it's operating backwards now.
I can hear the relay/solenoid clicking when I press the Emergency Start Switch, but it's just backwards!
In short, here are the symptoms:
Backup camera, power windows and jack alarm does not work in normal running mode.
If I hold down the Emergency Start Switch, everything operates normally.
Release the switch and everything stops working again.
It's a 1996 Allegro Bus 32' Gasser.
Any help will be huge!!! We're planning to head out in another week or so, but I don't wanna' go without my camera working!
