2015 Coachman Lepracan coach battery?

On our last camping trip the coach twin 12 volt deep cycle batteries just died. I installed 2 new ones today but no power, lights or reading of the moniter guaves. I cranked the Motor, then the generator cranked, and all work just fine, I turned the ignition off, no problem, cut the generator off and lights all died, no voltage anywhere
Sounds like a breaker or fuse somewhere.
Any ideas???

    Breakers are the first to check. Then fuses and then clean, strong battery connections.

    That happened at work to a new kid just out of tradeschool. He left the plastic cap on the positive post of the battery when he attached the cable.

    Sounds like battery disconnect is not on. Cycle system to off then back on.
    Next would be a fuse adjacent to the coach batteries.
    Battery fuse in the 12 volt DC panel

    Drems strange that when i cranked the coach up that the batteries came online, or seemd to, because the generator spun like they normally would with good batteries?

    When you started the engine, the house was operating off the starting battery, once genset was running, the converter took over.

    Ok, that explains that. I’ll be checking fuses and breakers today.
    Thanks

    The ground off my coach batteries was not making contact due to corrosion. Where the ground made contact to the frame.

    Checked all my fuses and breakers, all good. Everything works fine with the generator running, but still no 12 volt operation. Both batteries reading 12 plus volts. There were 2 small 5 amp fuses in the small compartmaent next to the battery box( in the steps) but both 5 amps checked good as well. Its a 2015 coach and this has got me stumped.

    Also my fuses are in the same breaker panel together. Guess i’ll pull the positive & negative leads and check for resistance tomorrow
