AGM house batteries
2016 Travato 59k diesel.
I took out my house batteries to test them as they were draining quicker than normal when boondocking. The batteries have tested fine at 1hr 12hrs and 24hrs so I put them back in.
Here is my problem I put them back in I believe the way they came out with all the same hookups. I am now getting b01 reading on my zamp but I can use my battery disconnect switch to turn power on and off like normal but not charging or reading as working. I switched the ground wire on one battery with another ans now I am getting reading on the Zamp like it is charging but now my battery diconnect does nothing.
What am I missing and does anyone have a drawing/diagram of the battery hookup? I have looked and have found nothing.
