Battery Light coming on. Low Voltage code

hey guys, New to the forums, i purchased a fellow owners 08 GC Srt8 with a prochager.
Recently when i get in it, once i let out the procharger belt will start squealing, And after a few secs the battery light will come one. if i turn the truck off and back on its goes away and dosnt come on during normal driving. i pulled the code on it today and its saying low voltage.
the truck has a new alternator, the procharger belt is new and tight. Has anyone else ever had this issue? or have an idea what i can do to fix it.

Alternator. Battery light comes on when the alternator doesn't charge the battery to a minimum of 13ish volts

Check the belt and tensioner. Could be slipping for a split second causing the light to come on
