2019 Thor Tuscany 40RT. Solar panels trickle charge the batteries, inverter powers refrigerator, auto generator mode recharges the batteries below 12.7 volts…
I entered the rig after 2 weeks unattended. Everything is dead. Engine fires up, hooked up to shore power and nothing powers on.
Any suggestions would be great.
A fully charged FLA battery at no load is 12.6 VDC. Why would the AGS be set so high?
So it sounds like your USE/STORE (battery disconnect) latching relay is open and the batteries died due to the generator running (fuel pump). Withe the house batteries completely dead you can't close the latching relay and you can't start the generator. The engine MAY charge the house batteries enough to close the latching relay after some period of time IF the BIRD/BIM can close the crossover connection.
