I have a 2013 Sierra truck with oem 160 alternator. I've already installed two batteries (same batteries/brand new). I'm running a front and back plow for residential drives. I can tell the alternator is just not keeping up. Should/can I change the pulley on the alternator to get amps around idle, or get a better alternator that has more amps at idle.
Thanks,
