Damm This Squeaky Alt Belt? Wtf?

[howslowcanyougo]

Got that SECOND Alt from checkers installed, and of coarse this one is good, cause I had it tested BEFORE I put it in this time.

Anyway now I keep getting Alt belt squeaks coming back after about a day after retightening it? I retighten it, the squeak stops, then the next day it starts back up, and I retighten again, again the squeak stops, and again it comes back the next day.

Over and over for 3 days now?

It can't be over tight yet, cause when I tried to loosen it, it squealed bad and got really hot, slipped I guess?

It also looks like atleast some of the belt is-was wearing off, because there was a bunch of black rubber belt dust all over the Alt this morning which I blew out with Air.

Looks aligned, feels tight? I'm out of ideas? Anybody else have this problem before?

TIA.......
