Battery not charging on 2015 Salem Forest River 5th wheel

Recently purchased Salem 5th wheel draining battery power. Came to the camper the other day after having no problems for almost a week and everything died. Replaced the battery and less than 24hrs later the same issue. What could be causing the battery to go bad? We traveled from Texas to Florida with no issues but we left camper hooked to the truck as we were just at each site for a night. Now that we are at semi permanent location and unhooked from the truck the battery died. We checked it and replaced it. Didn't even last 24hrs.

Well, something needs to charge the battery every day. If your not hooked up to the truck, are you plugged in to 120V power?? Running a generator?? You use a lot of 12V power and that battery needs to be charged through the converter in your trailer --- or you need to hook up a battery charger. The converter will get its power from your 120V source.

Sorry if I missed the point altogether here -----

Bad converter

We are having the same issue with our Rockwood Signature lite. As long as the camper was hooked up to the truck everything worked fine. Unplugged quickly the battery would go bad. (and we were plugged into electricity) After much troubleshooting we finally called the dealer and the service guy figured it has to be our converter. We are getting it replaced on Monday. Oh, and the TV in the living room decided to die on us as well. It was a rough start to a short vacation.

Also -- bruceatlam is correct, you need to hook up to a battery charger. Or stay hooked up to your vehicle. That is the only way we made it through until we got home. I had no idea of how important the battery was. Your refrigerator will not run without a battery, even plugged into electricity with the gas option turned on. Also, the awnings, slides, etc. won't work.

Yes we're plugged in. We had checked the converter but no fuses had blown. We have someone coming to look tomorrow. Definitely been interesting but that's the rv life right?

Sorry I should have said the battery wasn't charging while plugged into the 120v source

Our fuses aren't blown either. That is why we are replacing the converter. We have the extended warranty on the camper. We'll find out Monday if this isn't the cause but the dealer thought it was. Your issue sounds pretty much like ours.

I had the exact same problem on my 2012 Mini-lite last year. Only 2 years old. Turns out it was the WFCO inverter/charger. The DC side was completely busted. I replaced it with a Progressive Dynamics drop-in replacement unit and haven't had a bit of trouble since.

On (what I think is) an interesting side note ... I was having trouble with my propane detector going off even when the propane was turned off at the tanks. Haven't had that happen once since swapping inverters. Had to have been low voltage setting it off because the battery wasn't getting re-charged.

I suggest you test your inverter/charger ... especially the DC output. I'll bet a dollar to a donut that it isn't working.


If you do a little searching here you'll find a lot of people that have had trouble with WFCO units. I don't understand with Forest River keeps using them.


...................well, that's not true .... I think I know exactly why they use them and it has nothing to do with quality or customer satisfaction.

Did you all check you reverse polarity fuses?
They are separate from all the rest.

Does anyone else use a small solar panel to keep their batteries topped while in 'storage'. I don't recall the output, but it's about one square foot. I also put in a battery disconnect switch ahead of the converter. I turn the switch off before I lock up, so far no problem.

Do you have a volt meter? If so check to see what the voltage is at the battery while you are hooked to shorepower. It should be around 13.6 - 13.7 volts. If not check the wires hooked up to the battery and look for an inline fuse. There should be a fuse around 12 to 18 inches from the battery terminals on the positive cable. It is rare but sometimes it blows and will prevent the converter from charging the battery. A lot of people do not even know that fuse exists.
