No dc voltage at distribution panel 98 Monaco diplomat

I have a 1998 Monaco Diplomat. The batteies are charged and suppling 12 volts. The Xantrex 458 inverter is working and suppling 110 volts when I am inverting. I have no 12 volt dc at the distribution panel. I can not find a converter anywhere in the motorhome. There is a ciruit board in a outside compartment on the left side of the motorhome near the front wheel. On the ciruit board there is a 12 volt red wire that comes off the board and it is marked 50amp for inside distribution panel and I have power there. but not at the distribution panel in the rear of the motorhome. I assume there is a fuse or circuit breaker somewhere but can't find it. Has anyone had a issue with this in a Monaco diplomat.
Thanks
  • Which distribution panel?
    Is it the one next to the 120 volt circuit breakers?
    Have you checked the fuses/circuit breaker at the inverter?
  • Yes this is a new problem. everything worked last fall but as I was looking things over this spring I found this. The only switch that is by the passanger seat is a switch that turns on a reading light.

    From your three posts it sounds like it's new to you Beside the passanger seat there should be a covered switch that turns the 12V on/off.
  • Can't help with fuse/breaker location, but your Xantrex 458 is BOTH an inverter and smart charger.

    When it receives 120 VAC from shore power or generator it both "passes through" the 120 VAC to all circuits wired from inverter AND automatically charges the batteries (smart charger).
