Having the same problem you were. No power unless connected to shorepower of generator turned on.
I had a similar problem recently where my batteries weren't being charged when plugged into shore power but I did have the 12 volt lights in the coach. My initial thought was the battery disconnect solenoid which I couldn't find. I called Thor and was told that the solenoid was in the Battery Control Center which is located in the engine compartment, drivers side upper corner. Mine is a RV Customs Product, model TH-1020. Go to their site and download their trouble shooting guide. Their customer service was very helpful.
before you tear into the Control Center, check your grounds!!!! My problem turned out to be a bad ground connection to the frame in the coach battery compartment. The connection appeared good and were tight but it was not making good contact a/c rust. I removed all the cables, wire brushed everything, reconnected with new washers and nuts, as they were rusty,and ALL WAS WELL
. Hope this helps and good luck.
