Battery short

[jamieb1086]

OK, let’s get this out of the way. I’m an idiot. After finishing a nice service visit I brought my rig (2016 FC RTB) back to the storage lot. It’s Pennsylvania, its freezing out, so I’m in a hurry to get the batteries out so I can take them home and put them back on their smart chargers. While I have a rachet on the negative terminal on the streetside battery, I touched the positive positive side with the rachet. Nice spark shot out of the positive terminal.
The only thing working now is the jack. When I press the use/store button to use, the red light comes on and then goes out.
Checked every fuse and they are all good. Any ideas before I head back to service?
Thanks you guys!

If any 12-volt appliance fails to operate, rst check your 12-volt distribution fuse block, located behind the decorative front door in the front right-hand corner of the converter and inspect all fuses If a fuse is opened or blown, replace it with the same size fuse (never install a larger use) If the fuse opens again, have an electrician or certi ed RV technician locate the circuit trouble Replace blown fuses only with the same type and amperage size previously used
If the 8300 series power converter is not working, rst con rm the RV supply or shoreline cord is plugged into a live circuit Then check all the 120-volt breakers in your RV distribution panel to make sure they are on If the breaker is tripped, follow the instructions to reset the breakers If the breaker trips again, consult an electrician or certi ed RV technician.

Make some measurements, do you have 12V at the fuses?

One would assume you were removing the battery cables.
Did you tighten the connections before using the tongue jack? If not you may be getting a voltage drop.

Not all 12V breakers are auto-resetting. Some are trip-and-hold, which you have to entirely disconnect 12V power for the to restore service. Others are manual reset with a button you have to press on one of the narrow ends. I'm sure that, like everything with an Airstream, you could have any combination of the 3 breakers based on the mood of the installer that day or the season...

Yet another unresolved thread.

Ok here we go. I’m the OP. So I’m reinstalling the batteries (being very careful this time) to get ready to bring the trailer to the dealer to trouble shoot this issue. Everything now reconnected, I go inside the trailer, move the switch to use, and now every 12 volt item in the trailer works.
Since I was already started on the task, I took it to the dealer anyway. The rep that took me in wasn’t sure how this happened, but they are going to troubleshoot it anyway.

So the question is, there is obviously something in the 12 volt system that resets itself after a short. Question is, what is it? Maybe Airstream can chime in on this one.

In any case, if you do something dumb like I did while working on the batteries, wait awhile and see if the system starts working again. In any case, I will update after I get the rig back from the dealer.

So after I get the rig back from the dealer, they tell me they can’t find a thing wrong with the electrical system. Oh well. Just hope it doesn’t come back later and bite me in the butt.

My guess is that you tripped a breaker and that they are resettable. When you switched from USE to STORE and then back again, you reset the breakers.

NOTE: This is a complete guess. I don't know the first thing that I'm talking about!
