btw battery is new, alternator is new, and the battery connections are tight with no corrosion. no weak starts or weird stuff either.
same here. I've always wondered that mysleft.It IS normal!!! My 05 did it, my 08 does it, my Dad's 06 Armada does it, and if you search on here, you will find that EVERYONE else's does it as well. It is a self-reset as one of the guys stated. Perfectly normal for your gauges to do that after you shut the truck down.
