    not having a fox I have heard about the upgrade, but this is the first that I have heard about the 200 amp fuse........ Is that really what they recomend?

    A 3 foot section of 4 awg cable is only rated at 150 amps max fellas. You could take that length of 4 awg with its fuse and short out a good battery and the wire will melt before the fuse.

    you lookin at 0 awg if you want something that will last more then 200 amps.

    Hmmm, your probably right. I should step down my fuse to slightly higher than the alt output. More like a 150A fuse......

    But wait, don't most car batteries throw down more than 200 amps??

    yes and that is the point. The fuse is there to protect the wire. If the fuse is a higher rating then the wire can handle, your wire is now the fuse as it will glow bright orange and then start to smoke and melt, while the fuse sits unharmed.
