I replace my alternator because it was making a constant whining noise going down the road and I was getting electrical burning smell from it. Particularly when the engine was under load. And the brand new one does the same thing. Not the burning..just the same whine. Is that normal with some alternators? Note...there is no spring tensioner. You only tighten the belt down. My friend thinks it's because the belt is too tight. Is that also another posibility that it could be putting too much tension on the barrings?
