I was under the impression that the SH821 was. But I was wrong; it diode-checks as a shunt.

Well, frolicking puppies and rainbows...

I knew the SH775 is a 35A SCR series R/R, and the SH847 a 50A version of the same. The SH821 is a later (& still current) type; to my mind, it beggars belief that Ducati are still fitting SCR shunts to new bikes...

Ho-hum. Found a cheap source for SH775's (heh - Polaris have jacked the price of their part to $200 since the Strom guys discovered them at 60).

Least the 775 will be a straight swap ...

Sigh. Until comparatively recently, I did not share your cynicism regarding Ducati's bean counters. I see now that this was naive of me...

Yup, I believe that you are correct.

Having corresponded with Shindengen in the past, I pinged them an email for clarification and, to their credit, they replied straightaway:
FWIW, I'll say "sorry" to anyone I may have inadvertently misled...
