Hi, I dismantled my alternator today and I think I found the defective part. I am not sure if it is a resistor or diode. See the blue circle in the second photo. It is only this part that has no continuity. It first reads about 200M ohms and then it would become open. Am I on the right track?

If anyone has done a fix on this before, where can I find and buy this part? Thank you.

And by the way, while I was on it, I would like to replace the PCV but the thing cannot be pulled out easily. Is there a technique of pulling that out without breaking it? It is already broke and the other half is still stuck on the cover.

It is probably a capacitor (condenser), and, according to your description, in working order.

I may be telling you something you already know, but the diodes should only show continuity in one direction.

Thank you for the reply. You are correct! I connect a 12 volt house battery and it stored some voltage. So it is a capacitor.

What should I tackle next? Where can I find the voltage regulator? Is it the black thing that's attached to the alternator?

I visually checked the alternator, I didn't see any burn sign. The rotor's terminals read a negligible ohm. As well as the four terminals of the stator. Do you think that would be enough? Or should I turn the rotor and see if it produces an AC on the stator.
