Testing alternator and excessive AC ripple?

Looking back at the old post I cut above there’s a previous post stating the erratic tach and missing went away when he unplugged the voltage regulator both issues cleared themselves and it turns out it was a bad alternator. Should I unplug my voltage regulator and try it out or could I create more problems or mess something up by doing this as a trouble shooting exercise. 81080F98-AC75-41F5-BBA5-2376561977AE.png .
