Hey guys, I recently noticed my headlights and dash lights flickering while im driving down the road. I dont really have a lot of electrical accessories in the truck. I have HIDs for low beams, stock high beams and (4) Hella lights on the brush guard which i do not run often. I have also noticed the interior lights dim and voltmeter drop from 14 to about 9 when I roll my windows up. Just trying to get an idea of where to start before I start throwing money into it. Im not sure when the battery was replaced but I put a new alternator on it less than 2 months ago. Help! This is driving me crazy! Thanks!!
