This is the wiring diagram of the board that I built to help protect the Dolphin when the bridge rectifier blows or when the charger's fets blow. It has DC out for damaged pcb's. This very damaged Dolphin main board was reworked by Andy. With some more debugging, I got the board running on the bench. When I put in the truck for testing, this board blew up my charger. The fet driver was replaced and the charger worked fine after that
