".... I did complete the battery cable upgrade last night. I added a single stud-type junction block in the crawlspace to serve as a ground junction. From there, I ran a new 4ga ground cable from the converter to the junction block. I also ran separate 4ga grounds to each of the two batteries. I then ran a 4ga ground from said junction block to the frame ground. In addition, rather than removing the existing 8ga grounds running from frame-converter and frame-batteries, I also hooked them to the junction block, providing several additional redundant ground paths to the frame
So the two #4 wires going from neg junction to the batteries are equal in length for Method 3? (There was an issue before where the downstream battery --one above the other in racks) meant you had to go longer on either pos or neg to do Method 2)
Was the #8 converter to frame wire for its output before, or was it a "chassis ground"? With a deck mount converter, they say to have a chassis ground, whereas a "lower portion" converter doesn't need one, being in the metal framework of the frame-grounded power centre.
You added the #4 as converter output to junction stud, so unless there are more output terminals I am wondering if the #8 is a chassis ground. If so, you don't want that in with the negs on the neg junction stud. It should go to the frame independently. If it is output, you don't need it in parallel with the #4 to do 55 amps.
What happened to the parallel link wires between the two batteries? You don't need them with Method 3.
