Thanks Jimbo, you have pointed me in the right direction. As you can see from the photos mine does not have any reset feature. It is a metal enclosure with no visible reset button or device. The terminal posts are labeled for battery and auxiliary. I confirmed the cable size using a known 12 gauge wire placed next to the red wires in question and they are definitely no larger than 12 gauge. Cannot tell where the cable harness terminates as it is in a bundle of wire armor at least 6-8 feet long all zipped tied to multiple bundles next to the battery box. First I need to remove the nuts and clean the connections. BTW the coach is a 2018 Quantum RS26.
