Tired of GM alternators

I'm running a 10SI self energizing alternator on my Ford engine. I'm using the 1 wire system. I just replaced the front pulley with a billet one which comes with the nose attachment to cover the mounting nut on the pulley. I also have a idiot light connected that shows charge and a voltage gauge as well. Since replacing the pulley, my light no longer works the way it did. (doesn't come on without a charge) Now I have to rev up the engine to 3K rpm for the alternator to begin charging normally. Does this mean I have to replace the self- ignitor in the alternator, is it going bad? I believe I've replaced it before, or should I just replace the whole alternator with a different model. Any recommendations? 12si? etc. that are more dependable than the older model S10?
