A pre-fuse assembly designed to protect certain components within a vehicle electrical system against short circuits and to provide a user with easy access to a jump post for jump starting a dead battery. The pre-fuse assembly is a current-limiting electrical device that is mounted on top of the vehicle battery and includes fuses for limiting the current from the vehicle battery to a power distribution device and includes a horizontal jump post for providing easy access when jump starting a dead battery without increasing the overall height of the device. In one embodiment, the pre-fuse assembly includes a lower housing, an upper housing, a battery post connector, a master fuse, a fastener, a horizontal jump post and any number of other components.
