well i went with 1/0 gauge wire and just put a 150 anl until i can get a 300 anl (i figure under fuse is better than over so no melting). now it seems as though the alternator has alot louder whine to it. could this be because of the upgrade? also when grounding the chasis to engine does it need to start at the battery to chasis ground or can it start somewhere else ie. firewall, front radiator support (ClubGP Message Forum troubleshooting) something like in the second picture, but battery to chasis in stock location
