why would you put two fuses on one wire?
Yes they need to be fused after distribution (as close to the distro as possible), but not twice on a single run of wire if that's what you mean.
Because there's a battery at each end of that wire. One fuse cannot protect the wire if there's a battery at each end. Suppose something happens in the middle of the wire causing it to short to the chassis. With just one fuse, no matter where on the wire it's located, at least one of the batteries will still be shorted directly to ground, and cause a fire.
bought for a hella of a deal $250 Its a RF 100 farad cap. I wanted for when i need quick juice and the batterys are for slow juice =p. Overkill i know but, hey why not.
