I have no idea. I've changed out quite a few alternators in my lifetime and even ripped a few apart. I also know the basics of electrical motor/generator design. And nothing I've seen or know supports anything he's saying. In fact, everything I know says ugly is an ignorant, thickheaded douchenozzle. No offense man, but you need to do some more research on this and then come back and apologize. My first suggestion would be to go down to your nearest alternator repair shop. If they don't laugh at you, they'll at least set you straight.
