Bud and all,
Not to interfere, but I'm taking the liberty of asking whether actually
real data do exist to support the above statements. Or are they just
opinions ?
What if a regulator "fails abnormally", or a sense or control wire gets
severed ? The alternator voltage can climb to 100V peak in millseconds
if something goes wrong.
As in the past some builders reported different modes of failures for
their Ducati voltage regulator, I was wondering...
An overvoltage protection is no big deal, I would advise to better play
safe.
BTW, just in case; some electro wizard homebuilders here might find
information on the Rotax/Ducati alternator here :

Our study of the Rotax/Ducati voltage regulator will soon be fully
translated.
Any hard data to complement these webpages will be warmly welcomed.
