Ok, I left batteries hooked to camper with nothing on except 3 indicator lights. After 21 hrs the bat volts are 11.91 from 12.25. Thats to be expected and not much of a drop and everything works fine in camper at that voltage. Took bats out and are charging them now.
I found that the ITBC (integrated brake controller) on truck is not working. Not exactly sure how that would cause a drain on camper batteries but that is all I found wrong on the truck side of things. I guess it could cause a draw (???) as it is part of the wiring scheme???
Gonna replace it and hope that is it. Any thoughts???
With a camper, the blue wire brake line in a 7-pin is not connected :) , so the controller does nothing.
I still suspect the camper or truck side of the 7-pin of having a short. Everything behaves until you join them.
Did the camper lights all work
