Our Compass 23TR suffered house battery failure when new. That’s when I realized how lacking detailed electrical documentation is from Thor. In their defense, Thor customer service provided engineering drawings in PDF format that I used to make my own wiring schematic. These drawings also showed locations of transfer switch, ignition relay, use/store latching relay, 50 amp main 12V CB, E Start solenoid, & Isolator Relay delay module. Using drawings along with vendor information of the equipment provided enough information to complete my drawing. I have an electrical control systems background and it still took awhile before I understood how my Compass electrical worked. The isolator relay delay module & use/store mechanical latching relay is where the magic happens.
Keep searching and you’ll find the problem. With any trouble shooting, start at one end and work your way back.
Looking at my Compass system if I had your symptoms it would be the use/store relay or the 50A circuit breaker from the house battery.
Good luck,
Hugh
