I put the smaller pulley back on my Singer 320 amp hairpin and I swapped one of the stock alts out with my new Excessive Amperage alt. The EA alt has the smallest pulley out of all of them. Now I'm using the green belt, which is why it's not for sale anymore
Now I've got a Singer 370 amp large case hairpin, Singer 320 amp small case hairpin, and Excessive Amperage 300 amp large case conventional alternator. Almost 1,000 amps max and about 750 amps at idle //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
