POWER PANEL went blank. Generator the same

Please HELP.
2000 Winnebago Ultimate Advantage 38K. Pulled into campground with Generator running fine for 4 hours traveling. Using A/C along the way. Basement Air. Plugged in 50 amp and my Progressive Industries unit showed the L1 and L2 were good, CLICKED and let power into coach. Panel with A/C, furnace controls, Water Pump, Gen start, Hours meter, battery specs HOUSE and ENGINE, Tank gauges ect. Lights were lit up and I set the a/c. 2 minutes later NO AC and the entire panel was dark. Went to start Generator and NOTHING. NO light, no turning over. Checked interior pop out breakers... FINE, Checked power panel circuit breakers for A/c 20 amp or any breakers tripped...FINE. Checked breaker on Xantrex Charger Iverter...FINE. I have 50 amp plugged in and have the following.
Wall outlets working
Refrig, mocrowave and hotwater working
NO ceiling lights.
NO A/C or Heater.
It's Easter weekend and my wife is sick with me. In N. Oklahoma and nights are 30s.
Trying for Carthage, MO and Colaw RV Salvage for tomorrow.

ANY FUSES, BREAKERS SWTCHES I missed???

Thank you in advance
Happy Easter. Stay safe all.

    that and check the CB's ON the converter/charger.
  • OP has gone AWOL. Methinks something rang a bell. (salesman switch?)
  • I wonder if your battery died/shorted and took out the reverse polarity fuses in the converter.
  • Everything that's not working requires DC. Time to break out your voltmeter and start checking for DC. Use FRAME Ground and not some ground wire as it might be bad. Connections, main DC breaker, salesman switch/relay, etc all the way from the battery to the light circuit should revel the problem.

    It's not the the PI or ATS as you have AC power, can't even start the gen which also requires 12V DC.

    Good point.
    If/when you check the cables, tug them a little to make sure they aren't corroded inside the lugs. I had that problem about 10 years back on another mh. Cables looked fine until one pulled out of the lug at the battery terminal post while I was troubleshooting.
  • The generator itself has a breaker, but it won't prevent 12v from reaching the coach. Do you have a salesman switch? Everything you mentioned requires 12v to the control boards to operate, so it seems it could be a 12v issue.
  • First thought was ATS.
    Is the coach battery "salesman switch" enabled? It powers the displays in my coach, as well as the rest of the stuff you said is dead.
    Sounds like you've checked all the other stuff.

    Did you stop generator for 3 minutes before plugging in? IF not you may have fried your auto transfer switch

    Do you have a Surger Guard or other Energy Manager My first Surge Guard failed after many years. (It was a portable so bypassing was no problem)

    YOu said the power panel is dead.. IS this a 120 volt panel and what does it NORMALLY show.

    12 volt system is also needed for many things including most A/C's may be needed for the display on the power panel (I do not knwo.. is not on my 120 volt panel but is for everythign else)

    Hands on trackign it down is easy but remotely I got to rely on your eyes.
