Red Battery Lite

[SnowBuck]

2005 XL/SLT. Came on leaving the gas station. Took it to the Dealer. Parked & started again - It never came on again. They can't experience it. Everything tests OK...battery, alternator, wiring, etc. No Codes. What-the-hey???

That's for the alternator . Either under charging or over charging.
