I have a 2002 2500HD 4x4 that has been flawless for me and I bought it new.
Tonight, as I pulled in my driveway and paused for my daughter to get out, the battery light came on in the message center and my gauges all stopped working.

I have done the following:
Checked batteries [2 batteries, 130amp alt system]
Alternator output
Belt
Disconnected the batteries for a reset
Checked fuses

All appear to be working correctly. Truck starts/runs fine. Turned on the Hi Beams, A/C and operated the power windows with NO noticeable power drop/drain.
All other electrical systems function normal.

Any suggestions?????? HELP!!!!!!
