I just had the same issue. Mine was from the alternator as well. The alternator finally got enough wear in it that it allowed the main shaft to move rearward just enough to allow the pulley to slightly rub. As it warmed up, it expanded and moved away. We're talking thousands of an inch here, but it was enough to cause a horrible chirp.

Of course, rebuilding these alternators is near impossible anymore. When did we become such a disposable society??

Check this link. I can't confirm this is the source of your chirping, but noisy pulleys tend to quiet down after warm up. I regreased my pulleys 3-4 years ago and haven't had any noise since then. New pulleys typically don't have much grease in them either so save yourself some $ and try this first...

I bought a PA Performance alternator. Very nice unit. Just stay away from any of their units...or ANY unit...that is rated a lot higher than stock. You will have to upgrade your electrical system to handle it.

Oh yea...adding an additional charge wire is NOT an upgrade. That's a disaster waiting to happen.
