A two gauge wire will fine. Use a fuse that closely matches the rating of the alternator. The fuse can be 10 amps or so larger or smaller and it won't make much difference.gruvee87vertgt said:Guys, I am going to install a High performance heavy duty alternator.....is two guauge power wire ok? or should i go with zero gauge? also, should I go with 120 a fuse or 140 a fuse?
