i own a 1966 275 GTB long nose torque tube car. While the car was completely restored in the past 10 years the fuse boxes and wiring harness are original. The fuse box furthest to the right with the top fuse labeled Spinterogeni tends to overheat but not enough to blow the fuse but I need to spin/ replace the fuse periodically. The brass tab on this fuse holder shows signs that that tab historically gets hotter than the other fuse tabs . Also that fuse provides power to the bottom 3 fuses by way of a wire soldered to the rear of the fuse panel. I bought a reproduction fuse box which does not have the soldered wire on the back and as a result the bottom 3 fuses and all electrical devices attached to them don’t work. Anybody have any thoughts or experience with this issue?
