Battery not charging high RPM
Hi All. When I am on the highway at high speed the voltage gauge keeps bouncing low every few minutes. If I cruise at a lower speed it stays steady. Also if I punch it to pass someone the lights will dim way down and the battery icon will light up and I get a message "battery not charging". When the rpms come back down all is normal again. Anyone have this experience? Thanks

First make sure the belt is tite. Even if it's a serpentine, the idler may not be as stout as it was when new. Second get the alternator tested. Most auto parts stores will do that free.
