Thanks for update sounds like you know how to run the tester. That eliminates a diode as a problem, so the rectifier is good the regulator part does not have a "test" other than replace with known good and this; ground the green (outer lower) brush, do you get full voltage then? Voltage should go well past 14 volts when the engine is revved past 3K RPM.
Edited; because I shot from the hip and 5twins (gently) corrected my aim!
