are you serious....THE FUSE is the circuit protection devise....it protects the circuit from over powering the part by blowing itself up if to much current passes through it. It prevents you from having to replace a blown part. if the wire grounds itself between the load and the fuse...all thats going to happen is the power will come out of the battery, through the wire, through the fuse, and back to ground..There is NO surge of power just because the power found a differant way back to the battery.
