Connecting Battery Kills 12v System
Maybe this has been answered already, if so maybe someone can point me to the post. We're on a 3 week cross country trip with the kids in a 31' Jayco travel trailer. Had our battery system give us...

By disconnect, I removed the negative battery cable. Set-up is stock from Jayco, no disconnect or switch.
New battery was installed by our local RV dealer.
I did remove the battery and then reinstalled it. Would removing the battery and then reinstalling it lead to something like this? As far as reversing the polarity, I'm pretty sure I didn't reverse it at any time...black is + and white is -. Also, the reverse polarity fuses in converter are still good (per multi-meter).
I've been thinking some more on this, and perhaps I should share this...full disclosure.
As I mentioned, I removed the battery and reinstalled it. The reason I did this was to jump the tow vehicle...I'll explain:
Our youngest, somewhere between Amarillo and Roswell, decides he needs to use the restroom. We pull off the road and all take turns using the lav in the trailer (12 volt system working as the water pump was functioning). When we get loaded back up and go to start the tow vehicle, I get nothing...no turn over, no clicking, nothing. So, being in the middle of no-where, I decide to jump off the deep cycle battery. I remove it from the case, jump the truck, then reinstall it. Never checked to see if it was working...but at our lunch stop 2 hours later, nothing is working.
I was surprised that the truck wouldn't start. Battery in truck was in fairly good shape... Could an electrical problem with the trailer battery pull down the tow-vehicle battery?
