So I finally made the time to swap the board the Wednesday before Thanksgiving. Good news is the swap itself is not bad. Bad news is the board swap didn't solve the problem.
The hardest part about the swap is getting removing and reinstalling a blind ground screw that is behind the board that screws into the inside of the metal control center case. The only other glitch was that the crimp connector came off of one wire, so I exteneded and replaced that wire/crimp as well as a sister one to that wire. Not a big deal, just one of those things that happends when R&Ring a part like this.
So the symptoms are the same. When the aux cut switches are on, the battery jump solinoid is always energized, so when boondocking not only do all of the batteries discharge together, they discharge faster since the solenoid itself is drawing substantial current.
I have the service manual actual manual for the contol center and in troubleshooting it displays this problem, and the solution is to replace the board. Nothing further. I guess I will try to give their tech a call tomorrow to see where to turn next.
If anyone want to see pictures of the system, I did take some for reference when replacing the board
