Already have received a response from Randy, thanks!
Got everything put back together today in the motorhome. Had pulled breaker switches out, and pulled all of the wiring off of house batteries and engine battery, just to be sure.
Got Airstream all plugged back up to 'shore-power' and no problems so far. Even turned on A/C and no problems. Guess I know how to move quickly when my Airstream is about to blow up, huh?
Heading to Home Depot for voltage checker, and few other items. Has anyone ever decided to replace wooden blinds in motorhome? Guess it's time for a new thread.....
