ok i have behind the grille of my 2008 dodge 4 Hella 500 lights well the other night coming home from OBX i used them everyonce in a while because there's no lights down the side of the road and i was seeing deer everywhere. well i start up my truck the next day and my alternator is humming or should i say yelling louder than normal just on full blast but my batterys is fine and everything is working ok. do you guys think i need to find myself a performance alternator?
