Hello Everyone,
This is my first install. I was hoping I could get some help on why something was wired the way that it was. I bought a new Airstream 27FB just recently and have been installing a Battleborn Batteries GC3 system with all Victron Energy components and Renogy solar panels. While I've been doing so I've had to rewire and untangle a bit of what airstream did with the OEM build. I think that I've managed to untangle it in my head, save for one thing which I don't understand.
I've attached the wiring diagrams as well as some photos to help show how it was previously set up. The question I have, why was the negative post of the OEM batteries connected to the grounding bus bar? In the diagrams you'll find that their is the negative side of the breaker box/12v DC fuse panel also tied to the ground bus bar.
So on the ground bus bar you have connections to/from:
I don't understand why that would be connected in that manner. I had expected that the negative from the 12v DC fuse panel would run back to the negative on the battery.
In my new build I have the whole Lynx bus bars kit (Power In, Shunt, and Distributor) and a Multiplus 3k. I ran a 4/0 ground from the Multiplus case ground to the frame. Now I'm questioning whether I should run a negative from the Lynx Distributor to that same ground bus bar OR if because I have my Multiplus grounded that would account for it OR if I should run the ground from my Lynx Distributor.
Any help would be greatly appreciated.

So on the ground bus bar you have connections to/from:
- Ground frame connection (bare copper)
- Negative battery post
- Negative to 12v fuse panel/distribution
