Yes, but they’re expensive from Honda. I was able to buy one online from an alternator parts supplier. Also, if you have an alternator rebuilding service in your town they carry spares too.New alternator, or 'just' a new regulator? Can the regulator be bought separately?
Can the regulator be bought separately?
Yes but once alternator removed from bike, it's replaced quite easily by removing the rear end cover, no special tools required.The regulator is integral to the alternator so alternator will have to be taken apart to swap regulators.
Could you post photos of any labels/marks, particularly if it refers to Denso/Magneto Marelli etc… will help narrow down on-HOS parts.@Arellcat
I just wanted to let you know I have a spare alternator if you’re looking for one.

Any reason you couldn't wire in an external regulator?
It terminates one side of them for sure… I would say external regulator not worth the aggravation given you can get them cheap as chips (aka ‘fries’) on Aliexpress and eBay….I believe the regulator holds the housing for the brushes...

Brill, thanks @Al Gully...@canada_67

I even have the alternator rebuild kit on hand if you need that Honda stock number also.
Yes, two separate components...Considering that the cost of a new (aftermarket) reg/rec for my Africa Twin was in three digits, this seems like pretty good value. But that invites the question: is it just the AC/DC rectifier, or does it regulate the output as well? I had presumed the part with the heatsink was the regulator and that they were two separate components on the ST.
Either way, I have yet to pull myself together and start tearing the bike down, but I have delved into the Haynes manual a fair bit already. @Al Gully, thanks for your PM! I'll try to find a solution more locally, since the UK is doing its best to live up to its island status, but will keep you in mind.
