Rob and all,
I'm afraid I could not find any of those documents through a Google
search, and the Jabiru official website doesn't seem to list them.
Would it be possible to obtain a direct link to those pdf's ?
Thanks,
Best regards,
Gilles

Hi Bob,
I had the cowl off today so it was easy to measure. My engine runs
800rpm idle, which produces 7.2V AC. At 1000rpm I measured 9.0V AC.
Please not that these were measured with a DVM and the alternator output
is probably not a clean sine wave.
I didn't dare to leave the cockpit at higher rpm, but at 1400rpm my 'low
charge' light goes out. Assuming linear beaviour that would be at 12.6V AC
Hope this helps,
Rob

I was able to download using link above. I see
a citation for 12v @ 900 rpm and elsewhere
a citation of 40V at 3000 rpm. These two
values are consistent with each other.
This says that the paralleled winding produces
about 20VAC at 3000 rpm . . . this was the
value I was looking for.
Thanks!
Bob . . .
