I am not sure that anyone can help you here with confidence. Almost everything you listed is not original equipment. For instance a big question for me would be: Who added this equipment and is the installation documented?
Maybe we could suggest some help if you would state where you are.

My SM Pure Magic, hull no. 433, is presently connected to shorepower @ 220V, 60 Hz. During a recent inspection I was asked to operate the Onan genset, but overlooked switching off the small battery charger on the 220V switchboard before running the genset for a few minutes. Everything controlled from the 220V swichboard is working normally except the small battery charger which usually starts off at about 35A. Now the main 220V breaker inside the rotary autopilot compartment trips off immediately if I switch on the small circuit breaker. Resetting this trip and leaving the small charger off restores 220v & everything else on the 220V switchboard works as before. There is no sign or smell of overheated circuitry, but I think there must be a short circuit somewhere. I'd really appreciate advice on how to troubleshoot this problem or could the small charger be fried beyond repair? The small charger is a Victron Skylla-TG 24 100, if I'm looking at the right unit.
