hello my friend Filipe, I read your big problem, but I tell you, starts from the beginning, disconnect every cables and every circuits, start now in correct connection, cable by cable with a ommeter and see a any bad connection, if a possible error of conection, because I had a problem at wiring at articulation of cabin cut some wires, or any short at wires, see the diode circuit from motors. Well my friend good luck in your job.
