So many misconceptions in here. I just wrote a lengthy letter to Derek Lee because I am constantly seeing him tell people that an alternator that is rewound is no good.
What do you think the Iraggi alts are? They are stock frames, so why do they work?
Many of the aftermarket HO alts are exactly the same except they use better aftermarket rectifiers and regulators and sometimes outboard units. The problem starts with cost. Most people want it cheap, and that's just not going to happen. Anyone, and this is what most people do, can have a stator rewound and drop it in place. Theoretically, this will work, but it's neither correct, nor is it reliable. You also have to have the rotor rewound for a lower cut-in so you're not stuck running off the battery until 3500 RPM. The aftermarket for automotive rebuilding is huge and many of the suppliers have vastly improved upon stock designs, and produce components strictly for rewound, higher output alternators. Upgrade the rotor, bearings, rectifier(s), and regulator, and you should have a reliable, powerful alt.
BTW, I reman alts for a living and we do a lot of custom rewinding. . . The CORRECT way.
