Hi! I need some help! My alternator belt keeps slipping off.  Generally it does it early in the morning with the first start of the day. We are on the second replacement belt. The first replacement belt got chewed up.....this belt is still fine, but even after putting it back on and tightening it up it will slip off the next morning. I've gotten some input that it might be a problem with the tensioner...anyone got any other ideas. Alternator is in good working condition. Battery is brand new (also just replaced) and both belts are new too. Thanks in advance for any help! 

PS....It's a 1996 Mitsubishi Galant ES.
