Hey SimpleMan,
My truck will be in Jackson tomorrow afternoon and once I get all my stuff off of it (coming in for the lease program orientation and getting back to a good ole Columbia!) you might want to look at it.
Randomly, while driving down the road, the voltage reading will drop to 11.8-11.9 causing the battery warning light to come on. It'll then swing around from 11.8 / 11.9 up to 12.8 /12.9, back and forth before eventually going back up to 13.3 /13.4. It hasn't affected dirveability so I've been holding off having it looked at out on the road as I know it is more cost effective for the company shop to look at it. I have also noticed that since that started happening I seem to be getting shocked more (like static charge type shock). Starts fine, runs fine. Might be a minor electrical system hitch.
