Alternator Altercations

I replaced the voltage regulator(pics of old one to come) on the alternator with a used one today. I also cleaned the electrical contacts on the alternator, including the slip rings and contact points for the voltage regulator. I noticed that a wire on a terminal on the alternator had broken. Could this be my issue? Alas, no. It was signal wire for the tachometer. Yes, the tachometer signal comes from the alternator, a good reason why you need the diesel 55A alternator and can't put one from a gasser Volvo in it. Anyway, after reconnecting the tach wire, the tach signal is still in and out. This, coupled with the fact that the alternator is still not charging with a known good used regulator, would point to a bad alternator :( In addition, the alternator has the original Volvo sticker on it, a sign that it it is probably original and has never been rebuilt. Looks like I'm in the market for a rebuilt alternator...

Jerry, I have not had any issues with this. The pulley you mention, is it the crank pulley or the sheeve (attached to the alternator) send a picture? I am a little bit confused by what you mean.
