Battery light on

Wierd thing happen to me today i was driving and all of a sudden the battery light came on, and went of in like 2 seconds, now when the car is all warmed up and when i rev past 3 thousand rpm it turns on but turns off soon after ward, anyone what the problem is??

it could be a loose alternator belt

could be i’ll check that thanks

yeah its your alternator. see if your battery is charged. try to take off the neg cable off the battery and see if your car dies to see if your alternator is going. try a search on this subject.
