If it squeals when ur lites are on it is ur alternator belt most probably.The way to check it is tp press ur finger down on the belt 1/2 way between the alternator and main drive pulley.The Belt should not deflect more than 1/4 to 1/2 inch.If it is loose,loosen the adjusting bolt and the main mounting bolt,get a tire tool or big screwdriver and put it between the block and the alternator.Apply tension until the belt is tight andwhile holding tension tighten up the top adjusting bolt and then the mounting bolt.BJ
