Sometimes solid state goes bad on it's own.Sometimes the original fix isn't enough.I'd tighten the battery wires with pliers.Then I'd look for loose ground/positive connections all over the motor.<br />DHP

I agree with DHP... Most alternator problems either come from loose connections, or folks try and use them as a battery charger. <br /><br />3 months old... it is probably the regulator, then again, I have seen brushes get stuck in the brush holders. If it's under warranty, take it back and have it checked.
