[QUOTE="dr_peeb, post: 6279255, member: 613144"] You only need 1 fuse in your power wire; More than 1 is completely unnecessary, i.e does nothing. And, the 18" distance really means "as close to the battery's positive terminal as you can get it." The closer the better. If you get a cut in your power wire and it contacts other metal on your car (aka "shorts") the fuse will pop and kill the circuit, instead of your car possibly catching on fire. That same cut power wire shorting scenaro can happen by the bare wire touching other metal under your hood, like the inner fender, so again the closer you fuse the wire to the battery's positive terminal, the safer it is. A fuse is really an [I][B]automatic disconnect switch[/B][/I] that automatically halts power delivery immediately when something goes wrong, thus disconnecting the power from contacting anything else past the fuse location, thus eliminating the possibility of damage, and you want that switch located as close to the auto power source as possible.
