Ok this is my old post: Original Thread http://www.gmtruckclub.com/forum/showthread.php?52494-Alternator-issue
Now heres whats happening now and a little video to show. The lights also still dim a little and fluxuate at idle. PLEASE HELP MESo tonight on my way home I noticed my light dim a little, so I looked at the volt meter gauge and it was dipping below 14v where it usually sits and when I accelerated more on the freeway it would dim the lights more. I think its a alternator issue, has anyone had this issue before? I think tomorow I am going to pull the alternator out and have it checked at the local parts store.
Ok so I took truck to the parts store to have the whole system checked and it all checked out ok. I dont know what to do now because after a few hrs I came out of another store hopped in the truck and driving through the parking lot the volt gauge was way under 14v for awhile then it came back up. So now im lost and any advise will be greatly accepted
