Does anyone know what the current and voltage output is at idle on a healthy alternator on a 172 (cup) should all be the same?

Around 14.5v iirc.

14.5 volts or equal to at the battery if alternator is working properly

Alts don't output full current untill around 2krpm. Not sure on the rating on the 172 but itl be around 70amps at 2kish
