Where is the brakes grounded?Brakes are grounded at the A-frame. Few years ago, I installed two separate ground lugs to the frame (quality ones) and used stainless steel screws into the frame. One of the grounds is redundant in case one fails and connect together inside the junction box. That's were the brake cable is grounded. Should be well grounded there but will check.
Have you tested the voltage right at the battery with break-away pulled? No, not yet but that's a good idea for sure.
You need to trace the battery ground. Hopefully it goes to the frame and not just to the converter. Besides the grounds in the A-frame, there's a bare ground wire to the frame on one side. I removed the poor factory ground lug there a couple of years ago and installed a brass grounding stud designed for wet locations. Need to check that too.
