Bloviating? That "first post" might have been succinct and correct, but I learned nothing from it - you disagreed, apparently with Jerry or with Denny, or with???
Later, Jerry confirmed with a documented-reference that one-polarity voltage regulators were common. Denny only asked to see the document - he did not doubt Jerry.
And, as Denny notes, we also now know that many replacement voltage regulators can go both ways.
On the other hand, it should be noted that bloviation refers not only to "long winded" it refers to "empty and pompous". Where do we see that, above?
Thank you Jerry, and Denny, and others who continued to post information and documentation.
