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?

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.

Hello, I have a HR2. The battery is mounted in the back with a local ground. The
engine is grounded to the engine mount with a strap through a engine mount bolt.
There is a field of grounds mounted to the firewall. The field of grounds
is only receiving its ground through the firewall and no other straps. All my
avionics are grounded to this. My question is is the firewall a good enough ground
for all the avionics? Thank you.
