    So i've gone through several belts now on my alternator. The last two have ripped completely off. I don't know whats cuasing that but i do know that when i have the belt tightened down the top side is looks smoothe but the side from the crank pully is flapping like crazy. Whats going on?

    are you properly tensioning the belt? sounds like it could be a touch loose
    should only deflect about 3/8" under a fairly firm finger push on the longest section of belt

    Could be a bent pully,or a crack in a bracket.
