Battery discharge while on shore power.
Hello and good day streamers. I am really confused as to why my batteries would discharge while plugged into shore power and maybe someone with more knowledge could help me out. Recently I had my trailer in the shop and they confirmed that the batteries and charge system were functioning correctly. The attached image is my current battery levels while connected to shore power. When we awoke this morning, the batteries were at around 12.8. Any thoughts? Our previous trailer (SOB) when plugged into shore power would always read between 13v - 14v. Thoughts? Thanks!

You need to flip the shore power switch. In one position while on shore power it charges the battery and powers the 120V side of the trailer. The other setting it just powers the 120V.
The indicator to me on my trailer when the batteries are charging on shore power is the voltage reads 13.8 or close all the time.

Have you read your owner's manual about the Use/Store switch, or whatever it is called in your model?
Per previous comment, that switch must be On [Use?] for the batteries to charge.
Good luck,
Peter

Thanks for the replies and yes I have read the manuals and we are actively using the trailer, so of course the battery disconnect / store switch is on. I have not run a crossed a shore power switch unless you are referring to the battery disconnect / store switch.

Additionally, everyone keeps telling me the batteries will only charge from shore power if the battery disconnect / store switch is on. But... straight from the manual states otherwise. Either I am getting bad information, or the manual is incorrect.

Well, it sounds like the converter has gone bad or been switched off somehow. Or a loose connection. Or blown polarity fuse on the converter. Can you check the converter output directly with a multimeter at the converter? Is there a 110 volt switch for the converter somewhere? Is the breaker to the converter okay? Can you hear the converter running? And you are about done if you do not get it diagnosed and fixed. If the battery store switch was in the wrong position or defective I do not think you would have any 12 volt power at all.

Thanks for the replies, JakeS. Not sure what's up, as your 20' is different than our 2014 . . . above my pay grade at this point.
Suggest calling your dealer and the AS 800 number in your paperwork.
Good luck,
Peter

I would start by contacting whoever installed that aftermarket Zamp system, and ask them to check their work to make sure it is correctly connected, before proceeding further.

Thanks all, I'm really at a loss and will have to start making some calls to corporate to figure this out. It's really getting frustrating. Attached is the voltages we woke up to and also pulled out the paperwork the dealer gave me during my last warranty work as proof the converter was charging fine.

I had that same issue. Mine was simply a tripped breaker. Hope yours is something simple as well.

If your solar charge controller is faulty and/or the blocking diode is defective it could allow the solar panels to drain the battery at night.

I took the original picture at about 0730 and this new picture at 1004. I've only charged .1 volt in the last 2.5 hours. I only believe that was due to the storm breakup and a ray of sunshine for about 30 minutes to be honest. Yesterday, I did switch off all the breakers and checked all the 12v fuses. Unfortunately, I forgot to pack the multi-meter on this trip.

Charge Fuses
Does your unit have charge fuses and if so they may have blown. The charge fuses on our 2017 Classic are in the breaker panel below the wardrobe.

I do not doubt your 12 volt converter was working. It may still be good. But if you are showing 12.2 while plugged into shore power you are not getting output from the converter to the 12 volt system for some reason. So I think that is where you need to be looking.
I do not know the new systems or solar. I camped next to a new Airstream last summer and the gentleman had a similar looking problem. He unplugged the trailer and drove it to a RV place who looked at it and said it is working fine. He came back to camp and it did work fine for the rest of the trip summer. Maybe he just did not want to say what was wrong? Maybe just unplugging the whole thing and plugging it back in will clear the problem?
Can you hear the converter fan? Can you feel the converter to see if it is warm? You can pick up a cheap meter at Ace or Walmari. If you stay much longer you are going to need a battery charger.

I opened the cover of the converter and I can confirm that the fan has not kicked on since I've had the cover off. So I am assuming the converter is dead unless the fan doesn't run continuously. Without a multi-meter, it's really hard to confirm. However, I would like to thank everyone who has commented. It's really frustrating when the dealer tells you nothing is wrong and you get back out camping and you have the same issue you originally dropped it off at the dealer to fix....

Most likely the converter fan does not run continuously but is on a thermostat. But at 12.2 on the batteries there ought to be draw on the converter and the fan ought to be working. I would check the breaker for the converter again. Of course if a fuse is blown on the load side of the converter then it is not under load and might not heat up enough for the fan. My converter (not the one Airstream uses) has a reverse polarity fuse on the end of the converter. If someone reversed the leads during testing or changing batteries that could be blown. Or shorted a lead with the converter on.
Just another thought: My converter also has a LED on the end of it that indicates it is powered. Do you see anything like a lit or a dead LED on yours?

I believe the manual is incorrect.
I have a new 2019 FC 30' Twin. Mine keeps tripping outlet GFCI's when plugged (into a GFCI outlet at the house or the dealership) and the local dealer could not figure it out. It is now at JC for them to diagnose.
In talking to the service writer at JC I told him that the batteries and converter were replaced by the dealer because the batteries would not hold a charge. I told him that I had them on shore power since getting it back from the dealer. He asked if the battery disconnect switch was off or on. I told him off, because the manual says it will charge either way. He said no, only if the switch is on. I told him what the manual said. He said only if the switch is on. I was very clear. He was very clear.
I was very surprised by the answer, but going forward I will leave the disconnect switch on when storing on shore power between trips and pull them when in storage long term.

Thanks for the response. The dealer agreed to see me the day before we leave on our next trip next week. Hopefully it will be an easy resolution and we'll be on our way. However, a few comments from the top, I posted a picture of the manual where it states that the batteries will charge on shore power regardless of the disconnect / store switch. Are you able to confirm if the manual is correct or incorrect for a 2018 FC20 since their seems to be a lot of debate on this issue?

I know it depends on the model and year. On my FC 2017, the switch has to be in the on position to charge the batteries.
Have you checked the breaker for the converter? Have you confirmed that you actually have shore power coming into your AS? An EMS can prevent power from reaching your converter if there is a problem with the shore power.
