Charging issue? Belt tensioner, perhaps?

I'm unable to drive faster than 60, without the battery light coming on.

Battery voltage: 12.4 / 12.5 - Passenger / Driver side.

Not yet tested the output of the alternator.

Seems odd the alternator would/could function properly unless I race the engine, or run +/- 1900 RPM (about 60 mph), triggering the battery light to come on, as well as the voltage gauge to drop very low.

I suspect the belt tensioner is calling it quits.

Am I on the right track?

^^^^^Sure hope that bungee cord never fails....
Assuming it (or the bungee itself) doesn't fall into the fan.....
