Ugh.. Still problems with my belt!! Pulley Problem?

[Shinare]

(I know its a lot of words, but please read, I'm at a loss here)

OK, so I've changed my belt. The old one was terribly cracked and felt like plastic rather than rubber so I was glad I did it. So, just like the DIY says, I marked on the alternator slide bracket where the bolt was and tightened it back to that point with the new belt on.

It squealed horrendously and without ceasing when I started it. So I undid everything again and pried a little harder, and went a little past the mark. Tightened it all back up and started it. Sounded good so I left it.

The next morning it squealed when I started it up briefly but after a second of squealing it stopped. So I loosened it all back up and this time I tightened the crap out of that thing. I put my weight into it and tightened it even more. It only went just a hair past where it was, I could not tighten it any more unless I wanted to break something. Started the thing like 5 times and never once squealed.

This morning I get in my car after its been sitting over a day in the garage and right when I start it, its back to the noise I was having that started this whole dam thing. When the engine fires for the first time, you hear a slippage of the belt, but that's it. Then you are fine. But its that first kick over, its loud and just sounds like the belt is slipping just that instant.

Now, Do I some how try to pry on that thing even hard to make it even tighter some how, or is this an indication that something else might be wrong here?

I'm starting to wonder if one of those pulley's isn't messed up or something? If I were to take the belt all the way back off again, and spin each pulley, would they spin freely enough to just keep spinning if I spin them?

Also, should I be torquing the two alternator bolts (top bracket one and the one on the bottom of the alternator) to a specific torque? I'm just tightening them to where I can't turn them anymore, then putting on a small cheater bar and turning a little more.
