Had the same problem. But only after I killed the battery because ofleaving the lights on. Boosted the the old sow and the squeel started, no doubt the draw on the battery was making the alt work hard. After a bit of driving the squeel would not go away. WTF I changed thebelt and like a previous response I "reefed" the belt tight and no squeel. I'll probably have to tighten the belt some more because of stretch. 10,000 later no squeel and no belt adjustment yet.
