Generator Onan 5000 problems

We recently purchased a 2001 Winnebago Adventurer. We had the generator running last week, but when I tried to start it yesterday, it didn't even sound like it was tring to crank. It made a beeping noise when I held the start button down. I had the motor running also. The house battery runs itself down very easily and the 2nd house battery was never hooked up. Anyone know what the beeping noise from the generator might be??
I also can't get the gas heat to run off the propane anymore, but there is still propane in it.
Everything was supposed to have been working when we purchased it in Dec., but who knows!
Thanks!

    First, WELCOME to RV.net!

    Your generator usually starts from the House Battery(ies). Running the road engine will help the House, but if that battery(ies) is/are really low, generator still isn't likely to start.

    Are your house batteries Six or Twelve Volt? I'm trusting they're Twelve because if they're Six and only one hooked up, nothing would probably work.

    Your furnace may burn propane to produce heat, but it has a Control Board that is 12VDC and runs off your House Battery! Same for your Fridge and probably your Water Heater.

    I think you probably have House Battery and/or Connection problems.

    But ALWAYS ALWAYS ALWAYS post the Make/Model Number of things like Appliances, Generator, Chassis, etc.
