so here's the deal i parked the truck awhile ago because i ended up getting my car out earlier than expected, and been driving it cause it's been nice out, anyway i went back the other day to drive the truck and it wouldn't start so i figured the battery was dead from sitting, no problem boosted it drove fine, went and hung out with some friends uptown and tried to start it and it was dead, so i figured i'd buy a new battery the next day and all would be good. So on to the next day i went and got a battery and worked fine, next day it started to spit and spudder and died, so i went and replaced the alternator, fired it up worked great, but the battery light was still on through all of this, so i checked the voltage across the battery and it was 12.8v and while running it was fluctuating between 14.25v - 14.1v and would occasionally drop to around 13.8v - 13.5v engine sounded like it wanted to died, anyway i'm kinda at a lost of what it could be i looked through the forum and was thinking maybe a ground or relay or something, but i wouldn't know where to start looking, any help would be appreciated
