Thanks javelin, for the suggestion of disconnecting the batteries and seeing if house lights will work while on shore power. Will try that later this weekend. I plan to disconnect them anyways to save them from deep discharge while I'm not driving (alternator is the only charging source). I did locate my transfer switch box behind the drawer but haven't taken the drawer out...
Bit of an update:
I did call Thor customer service again and had lengthy conversation but no recommendations other than see the dealership for troubleshooting problem.
I still want to have the transfer switch wiring checked. So Stopped by the dealership as it was on my way home but no one able to check it. Now I need to leave my Gemini there for a week in JULY....and that is if all goes well:-(
