Heater Issues

I am new to the forum, I own a 2006 Forest River wildcat 5th wheel. This weekend I went to the desert and tried to run the heater on the fully charged battery and then on a generator and it wouldn't work. I couldn't even get the fan to operate on the heater/air unit. Note: The regular lights all came on with the generator and all other items operated as normal under battery power. when I got home I plugged it into 110 and it worked fine. Any ideas why it wouldn't work in the field and how I can get it operational on the battery/generator? Thanks for your help!

are you talking about the RV's furnace or a plug-in heater?

You have a 5th wheel with a built in generator??
Would your lights work on battery power??

NO, the generator was external. The lights that worked on the battery were the standard 12 volt lights. THe remaining lights work under external power and all of them worked with the generator. The only thing not working under the generator was the RV Furnace. Which, for some reason, did work when I came home and plugged into the 110 outlet. By the way, thanks for your assistance

How big or little is that external generator? It provided good AC power for other things in the camper?

Your furnace is a 12 volt system so it should run off the battery unless it's dead. Since the furnace worked when you got home and plugged into 110, my next step would be to unplug from 110 and try it with the genny again. BTW, if the battery is the original that came with the 2006 Wildcat I would replace it. It is also possible that your thermosat is beginning to go south on you.

The generator is a 5000 watt industrial generator which ran everything but the furnace. The battery is one year old and held the charge very well once it was off the generator.

Battery connections loose/corroded/not connected properly?

Give them a once-over to be sure.
