[QUOTE="k_schutte, post: 6772385, member: 551817"] It is an AC Delco AD244... tested one and got 225A~ at engine idle (700rpm) when cold then dropped down to a steady 120A~ at engine idle (700rpm) when warm. It tested MUCH better than my Iraggi 220A and a "no name" 300A we had on hand. GREAT alternators and you can get them on ebay for under $100... IF it will work on your engine... honestly though, for only 750 watts, I don't think you should have to do shit unless your alt is going bad or something... EDIT: looks like the AD244 will work for you... some of the vehicles they came on, the bigger ones will generally have the 145A version, not the 130A. Personally the one I used was from a 2004 Suburban IIRC... got it on ebay for like $65 shipped and that is the one Beusings Iowa Generator tested for me. Out of 4 alts, the only one that beat the AD244 is my 300A O.G. alt with a much smaller aftermarket pulley on it and it beat it by like 50A all around IIRC.
