Do you by chance have underdrive pulleys on there? RPM is about the only thing that will affect charging voltage the way you describe. Could maybe be a diode open. That will not necessarily show up on the autozone test, they spin it at normal speed, not idle

, probably a bad diode trio. Look into having it rebuilt if it's a numbers alt. If not, consider upgrading to a CS130 or CS144.
