Our 2023 Jayco RedHawks battery is not charging when plugged into a shoreline. We are boon docking at my sisters house and we are plugged into her house. The power is good going in but running the heater is killing the battery. We are cold. Help! TIA
Check your battery disconnect that it didn’t come loose.
Then check your fuses.
Had the same thing happen to me and it was the battery disconnect had gotten bumped.

First test, do your 120 volt items (microwave, tv, AC) work? If not then the shore power is not making it into your rig and the result will be no battery charging.
If the 120 volts items don't work, check your main breaker and cycle it. Verify there is voltage at the outlet you are plugged into.
If the 120 volt items work then check the breaker for the converter and cycle that. The converter is what charges the battery by converting 120 volts to 12 volts. There is a possibility that it failed if the breaker doesn't solve the problem. That is unless you somehow reversed the battery cables at the battery which could have blown the reverse polarity fuses on the converter. A loose wire at the converter, although rare, could kill the output power.
A voltmeter will be your best friend. In case you aren't real familiar with voltmeters, I have attached some documents I created. Good luck!

If none of the above is helping check the posts of your battery and fluid level. Even a minor looking amount of corrosion on the post or in the connections will stop current flowing. Also, should be a fuse or breaker near the battery. Check that and the connection to the grounding to the frame. If a cell has boiled dry it could be the battery itself is bad. If all else fails, shut off the battery and put a charger on it for a few hours and see if it holds a charge and if the power is getting to the lights and other 12 volt items.
Somewhere there is a fault, just got to keep digging!

In trouble shooting before you check fuses, disconnects, go to the source of the problem and check the battery. Remove it, take it to a local auto parts and have it tested

The battery is a good thing to check, but if plugged in to shore power, the furnace should run fine just off of converter power without a battery even connected. I think that either the converter is bad, a fuse is blown, or there's a loose connection somewhere.

We also are having the same problem. We have a 2007 19' Jayco Travel Trailer. Took it to Bradenton for Christmas, and within days the battery was dead. We were hooked up to shoreline, the microwave and AC worked fine, the frig went down as well as all of the 12volt lights. We haven't had it long so still trying to figure it out so any ideas would be appreciated.

Converter.. Check the breaker for it. If you're plugged into shore power everything runs off the converter. You shouldn't need the battery.

So you're getting 120 VAC to the trailer, but not getting 12 VDC to the battery. First check to make sure you're getting 120 VAC to the converter. Then check to see if you're getting 13-14 VDC out of the converter. If you're not, either the converter is bad or a reverse polarity fuse (usually on the converter itself) has blown. If you are getting 13-14 V from the converter but not at the battery, then the problem is probably a loose connection or blown fuse between the two. Trace the line. JimD's multimeter and electrical troubleshooting documents above are very helpful.

Thanks for responding, this age and size should have a converter?
Its very easy to be confused between a converter and an inverter. A converter takes 120 VAC power and converts it to ~13 VDC to charge the battery and power 12 V appliances. Pretty much any RV that has an electrical system will have some kind of converter. An inverter does the opposite: it takes 12 VDC power from your battery and inverts it to 120 VAC to power some appliances (e.g. a TV). An inverter is becoming more common but is often optional and may not be in older and/or smaller RVs.
So, bottom line, you almost certainly have a converter.

I had this same problem last year. the converter was bad, and I was on a trip. if the converter is bad, you can get a battery charger and charge the battery. get one that also will do a "maintenance charge", and just leave it charging until you can get it fixed. I was one a five week trip, and did this every night.
