Nigel, Gilles
I have had the same experience as Nigel during systems failure mode check
outs. Once the regulator was excited it continued to run.
I suspect that there might be some variation between regulators that account
for this. Actually (touch wood) my regulator has 470 hours / 2.5 years on
it and so far it is holding up well. I am hoping that a combination of a
modest load and a cool location is going to keep it that way.
Regards, Paul

All I can say is that after having done an external battery start one
day I forgot to reinstate the onboard battery before disconnecting the
external power so hence the comments below.

Hi Nigel,
We run the regulator that came with our 914 on the bench, and once
disconnected, it won't come to life if the battery is down or off line,
regardless of the RPM. This lead to a series of scenarii where we could
be left with no power.
Of course it is possible that not all Rotax regulators are the same
internally, or you found a particular mode we failed to explore in our
experiments. I would be interested in more experimental details on your
findings. I could publish them in addition to our measurements.
Best regards,
Gilles
