On a trip this past winter, we plugged into shore power at a campground. After 3 days, lights, fridge, furnace all stopped working. I checked house battery and found it to be dead. Replaced the battery and that worked for a few days before everything died again. Returned battery thinking that was the problem, it wasn't because it happened again. Recharged the battery, then headed home taking 6 days with no more problems. Since starting camping this past spring, have had to keep charger on battery to keep everything going. I checked the fuses and they are okay. This is a Jayco 2001 Class C. The furnace in our travel trailer never did this when the battery was dead as long as we were plugged into shore power. Anyone have any idea of what to do next?

Sounds like your converter isn't functioning or the fuse between it and the battery is blown. Do you have a meter? Cause you're gonna need one to do some testing.

Doesn't sound like converter is charging battery when connected to shore power.Check battery isolation switch in ON positionCheck reverse polarity fuses on converter....may be blown. Two Large Amp fuses 30A-40A)Check for AC power to converter when on shore power (outlet OR AC circuit breaker)Check converter DC Output when on shore power..should be 13.6V DC

It sounds like a converter problem. With a voltmeter, check the voltage at your batteries. It should be 13.2V or higher. If it isn't you are not getting power from the converter to charge your batteries from shore power. This can be from a bad connection, bad converter or the converters 120V breaker. If you can find your converter, check the voltage across the red and black terminals. Again it should be 13.2V or more. If it is, you have a bad connection between it and the battery. If it isn't, you need to make sure it is getting 120V AC. If not research why - it could be a circuit breaker or bad connection.

I also think it's the converter...after all, your converter is 12 years old now. I had the same problem last year, replaced the converter and it's worked fine since. My only suggestion would be to install a "good" converter (which means it costs more money) instead of a cheap one. I went from a WFCO to a PD because of all the positive comments on RVnet and no problems yet. Hopefully you'll get 12 more years out of it. Good Luck.

Are you sure it's not a inverter instead of converter? I don't know the difference.
