Battery Disconnect and Auto Leveling Not working

[OldKingKibitzer]

Brand spanking new to RVing!

2013 Keystone Fuzion 310. Not realizing I had to have it plugged in to keep the batteries from dying...I let the battery die. I currently have it plugged into my house GFCI outlet. I unplugged it last night so that I could close the door and I clicked off the factory battery disconnect. This morning I go out (Not yet plugged in) to check to check the battery level and the disconnect button does not work- It used to click when I pressed it. It will not turn back on! I plugged the RV back into my house, the inside lights work however the Auto leveling (Where it will read the battery voltage) does not work and it will not allow me to turn on my generator.

Help!! Any thoughts? Is there a fuse specifically for the battery disconnect? Why won't the Gen turn on or prime? It seems nothing is getting any battery power. I don't have any blown fuses in my fuse box...So I'm fairly baffled on how to proceed!
