Well, this just got interesting, Dad was going to pull the alternator while I was at work and luckily decided to check things out first. Everything worked fine, even under load with the lights on and he was getting full voltage out of the battery (almost 5 y/o now and gets charged via charger more than the truck itself) and the truck was putting out 13.75v with the lights turned on. He took it to a parts house and had them scan it and they pulled a P1682 Charging Output Low code out of it, ofherwise, the damned thing was fine.......electrically at least:banghead:
Is that 13.75v ok for the OBD2 trucks? Dad said it was ok on the older Mopars he's owned.
