this is my alternator / starter guy his name is Steve! he can hop up out put power as well! for instance a 90amp he can beef up to 120amp! he can add a "W" terminal too!
I bought 3 alternators over a year ago just to have them on hand because i was going through alot of alternators from crapa napa now since i got those from Steve i have not had any problems and thier heck of a lot cheaper then going to your local part store and i can get what ever output amps i desire! right now i have a 140amp on my AAZ and it runs my tach real good! so if you call him just say you know Duane from wisconsin i'm sure he will remember me and give you good service!
