B2650 change to alternator

All,
I know there are a few threads on the project to replace the magneto on the B2650 to an alternator, but I have a few questions that I did not see answered in those other threads:

- I see a few different versions of an alternator that, from reading previous threads, will work on the B2650 (although that model is not specifically listed. 16241-64013 is the most current OEM part number I see for that. Question is, would you all strongly recommend paying the extra for the OEM version or is after-market fine? If aftermarket, are there some sources for a better after-market version than others?

- So, forgive my ignorance... Does the current configuration (with magneto) utilize a voltage regulator? If so, is it integral to the magneto or a separate part? I did not see it in the wiring diagram in the WSM.

- If the voltage regulator used with the magneto is a separate part, can that be used with the alternator?

- If a voltage regulator is required and the one used with the magneto setup is not appropriate, do the alternators (OEM and/or after-market) have them on-board or is it a separate part I need to purchase and install?

Thanks for any input/advice you can provide. I am generally pretty happy with my dealer, but the parts guy has not called me back re: the alternator so I still have these questions.

Thanks,

Dean

Wolfman,
Thanks very much for the info. Oops... yes, dynamo, not magneto... I guess I had superheroes on the brain .
Okay, that's kind of what I was expecting/hoping to hear about a separate voltage regulator and the fact that the alternator has one on-board.
I will have to check my p/n source...likely a typo on my part but thought I copied it from Messicks web-site where they reference the replacement part for the old p/n I had.
Thanks very much for the eBay link... that second one to the OEM Denso alternator is a much better price than I was seeing elsewhere.

By the way... I used to visit your fair town back in the late 70's when I lived in western Montana. Sandpoint was the closest city that had real grocery stores and a couple of good sporting goods stores (can't remember the names but one was downtown and the other was on the outskirts a bit... was one called Pastime?).
Had a stepbrother that worked at the shake(?) mill and was a taxidermist. Stepdad had family in East Hope.

Thanks again, Dean
