Shore power not charging battery

Try these:

1. Clean the battery cables really well and reinstall. Any help?

2. If you have a car battery charger, plug it in and hook it up to the battery of the camper. Any help?

If its number 1, problem solved.
If its number 2, have the battery tested but it could be your inverter has gone bad.

My guess is time to replace inverter. If you're out camping, a battery charger left on the camper battery will work just fine. Just replace the inverter when you get home.

Good advice but you really meant to say Converter not Inverter. Which is what most Fifth Wheels have.

Hooked up to 50A shore power......
Then Converter should be supplying the DC system and recharging battery

Check the 120V AC Circuit Breaker that feds the converter. If tripped no AC to converter -- No DC from converter ___ Battery low cause no recharging being done

Or if converter has power cord.......is it plugged into a 'working' outlet?

Again circuit breaker for outlet tripped or GFCI feeder outlet tripped????

Check converter DC output.......S/B 13.2V minimum for a functioning converter

Just had the same exact issue. Turned out my convertor blew a fuse. I actually replaced the single 12 volt battery with two 6 volts.
If the convertor fan isn't running then it's probably the convertor

your converter should have one or two 30-40A catastrophic fuses somewhere on a front panel. That would be where I would start my troubleshooting.

When we had a similar issue, it turned out to be the Converter AC Plug had worked it's way loose in the outlet. Reseated and used cable ties to keep the plug in and no further problems.
Also on some units if the Battery Cutoff switch is activated it will prevent charging the battery.

Those would be the 'Reverse Polarity' fuses.
Strictly there to prevent damage to converter electronics IF battery is hooked up backwards.
If battery cables have not been removed.....those fuses should not blow.
Only when cables get reversed.

How old is the RV? On older rigs the power panel did not use a battery "maintainer" type of charger that all of the modern panels employ. If you cannot hear the cooling fan cycling, and the rig is older you may need to upgrade the panel.

Can you hear the converter humming? If not then solve the NO 120V problem... could be as simple as a tripped circuit breaker or as Michelle.S posted, it's come unplugged. If it's humming then check fuses and connections. If you are getting 120V in and no 13V out, the converter is bad.

Same thing happened to me. My PD9260 has 3 fuses on it, two were blown.
