Moving Refrigerator circuit from House Battery to Lithium bank.

First, thanks to everyone who has helped with opinions on possible upgrades.
I ended up going with a redundant power system. Probably from the Aviation bug I caught years ago.
I am exploring moving my Refrigerator circuit from my House Battery (120AH lead acid) to one of my Lithium batteries powered by solar. I believe my system is non-isolated do to the negative post wired to the frame. I found the possitive refrigerator wire that runs to the circuit breaker and would like to reroute it but the other-side of the breaker is just hooked to a common wire. I assume it is going to ground. I also assume the other wire from the Refrigerator is going to ground making it imposible to complete the circuit. No way I am pulling out the refrigerator. Any ideas. I did get a good deal on a 75 amp lithium converter to replace the 55amp lead acid converter, but have not installed it yet, So many posts of people frying their alternators even with the LI-225 BIM installation. Any opinions on this? Thanks in advance!!
