are you running the alternator + to the battery + with this? the original post says you are, but you ran the battery - to chassis with 0/1. i would use the 0/1 for the alt + to batt + so you only need 1 fuse.
you said you already crimped so hopefully you're just using ring terminals or something and can swap this around. doesn't sound like you've fused the + to + wire at all atm unless you threw it through the main fusebox which would be silly for an aftermarket alt.
