Key Details of the SH821AA: Type: Series Regulator Rectifier (often categorized within the Shindengen MOSFET series, though, unlike earlier SH-series, it specifically acts as a series regulator to reduce load on the stator). Manufacturer: Shindengen. Bung in a best offer, cheap route to a series R/R https://ebay.us/m/cPCG30
I disagree, Shindengen do make it confusing. Older SH designation are the old shunt type. That includes the 821. The new series R and R they are producing are also named SH. Anyhow, it's a good spare to have.
Sorry Chris = does this fit my hyper? Edit learning mode activated.....so these mosfet/shindengen ones will fit both my hyper and RSV4 (both have lithium batteries fitted) - ive got the little loom jobbies bookmarked also but i can press new cables if i need to and tbh with the RSV4 ill need to as the loom side melted years ago so i replaced it...
With Lithium batteries it seems this would be the way to go https://www.ducatiforum.co.uk/threads/ultimate-rectifier-reg-recs.105000/#post-2320113 Not cheap though.
