 You are correct Bob McC.  Whatever language it is, it is Greek to me.  



Bob, Joe and all,
	




Windows 8 doesn't seem to like my old backups, but I may be able to 

retrieve most of the original article and spreadsheets we crafted at the 

time with Jerome.

In French only, I'm afraid.

Translating the whole article in English would be a major undertaking, 

but feel free to ask if you need some clarification as to the meaning of 

any term or paragraph.



Season's Greetings

Gilles

If the link above is to your article, by opening it with Google you can 
	


get a rough translation to English. Won't be perfect, but should be good 

enough to understand what's going on in the article.

Hi Eric,



The schematic was a best effort in 2008 by someone who called himself 

Arrow on a German forum.

By disassembling a Ducati regulator.

I'm sure there are errors (beyond the battery symbol).

He identified the mechanical connection of the diode pills as the weak 

point.

Workaround external diodes.

Unhappy with Rotax.

Forum pages have long gone.



Gilles had a similar effort on his website once (similar but different).



Buyer beware.



Cheers,

Jan de Jong.

 I hesitate to inject my questions about the schematic of the Ducati dynamo regulator. But what is that little unlabeled zener diode feeding the base of the BF493S?



 And why does this look like an alternator regulator instead of a DC dynamo regulator? What am I missing?
