Alternator/charging questions

RedFish said
Sounds like chrome alternaters should be offered as empty housings to build a quality unit into. Good luck with it.

I changed everything from my good alt except the rotor, and I guess my questions was can the rotor cause these symptoms? Can I get the billet pulley off without damaging it and can I do it without a press or junk all this and get a tuff stuff or powermaster alt or a one wire?:-k
