I think a loose/defective belt is the most likely too. As the engine warms up and expands (slightly tightening the belt) and the alternator warms up and runs freerer, this may well produce enough output that the idiot light goes out. Second guess is the regulator isnt delivering the juice in the specified amounts. Good luck.
