Upon a few tests with 6 gauge wire and a andreson plug tied to the 40 amp mega fuse, the fuse would blow.
I did the same mod several years ago so I could load support my single G27 trailer battery with my Avalanche but since it didn't have an aux battery I pulled directly from the truck battery with it running. I used 10' of 4 gauge booster cable for minimal voltage drop and that worked well ... what didn't were those same Anderson SB-50 connectors it looks like you've used, which burned & melted. I recently bought a new 4 gauge booster cable and this year will be load supporting my new G31 AGM trailer battery with my Silverado but this time I won't be using those d***** Anderson connectors but instead will clamp directly from the truck battery and truck chassis ground. I still have those Andersons and can take pics if you need proof ... JMO but I'd get rid of them before yours too melt.
