Battery indicator comes on at 4500 RPM
I have a 2005 Fx4 automatic and during hard acceleration when the rpm's get around 4500+ the battery light comes on, once the rpm's go down some it goes off again. Has anyone else ever seen this?
I don't know if the alternator is not able to keep up at higher rpm, or if it's producing too much voltage.
Thanks
JK

Check your tensioner for its amount of travel (you are also trying to determine if the belt is stretched).
If tensioner is strong and belt is good, it'll be new alternator time soon.
High rpm Volts light usually means the brushes are worn down to the point that spring tension can't maintain brush contact = replace alternator.
