When my car hits 3000 rpm or higher my dash battery light will flicker and go on and off. Not sure why.

Newer battery (6 months ), all battery cables snug, belt is new with 1/2 inch of play and not slipping, wobbling or making any weird noises, and battery charging between 14 and 14.43 at the highest output so it's not over charging.

What is the battery light trying to tell me? The battery is staying charged and is charging well when the light is both on and off. I see no change in charging power whether the battery light is on or off.

Any suggestions appreciated.
