Second Batt help

THANK YOU! Ok but why do I need to fuse the positive cable three times. It looks like there are two fuses on the same set of wire. That doesn't make much sense?

If the wire shorts after the first fuse, the first one won't do any good when both sides are hooked to a battery, same thing the other way, that's why two fuses on one wire.

if the wire shorts out inbetween the batteries, both fuses will pop so that one battery or the other will not continue to short. if you just had one fuse and the wire shorted in the middle somewhere, the short would continue to be "back fed"from the other battery.
