Ben, This isnt really rocket science guys, below is a wiring diagram from Service Manual 2029 A JOHN DEERE PUBLICATION IT IS NOTTTTTTTTTT MY OPINION OR DIAGRAM.

As it shows the mid center tie point of the series connection (two 12's or four 6's) IS BONDED TO FRAME GROUND. The reason why is so there exists TWO 12 volt circuits (to light switch, the A & B circuit feeds) for lights etc WITH RESPECT TO FRAME GROUND. One circuit is Pos ground the other is Neg ground. YES the remote electrical socket is connected to ONE of the batteries as shown and that is part of ONE of the 12 volt TO GROUND circuits that could furnish 12 volts to say a remote device or an implement or light etc.

ITS TRUE YOU DO NOT GROUND EITHER OF THE BATTERIES AT THEIR OUTERMOST UNTIED POST (ONLY at the mid center junction as shown) because that would indeed create a dead short to ground across that particualr battery and GO POOF AS WALT MENTIONED !!!!!!!!!!!!!!!!!!!! The bond to frame is ONLY at the mid center junction as shown and for the reasons I gave

Im NOT here to fight ONLY to help others and Im showing and describing how John Deere wired the system originally and trying to explain why they did so but hey its your tractor and you can wire it any way you see please.....

Yall take care now

John T
