Had a similar problem of spiking up to 16 volts at cruise throttle. Replaced
the
regulator and all has been well, currently at 385 hours. The problem occured
at about the 200 hour time. Now I wonder about the 400 hour interval just
ahead.

Hi Folks,
I have 210 hours on my Europa now and was merrily flying along minding my own
business
when the crowbar activated. I had this problem about this time last year
and Bob Nuckols adjusted the crowbar to activate a little less sensitively
which appeared to solve the problem.
I reset the circuit breaker and all seemed well for 20 seconds or so then the
volt
meter went from a normal 14 volts to a spike of 16 volts when the crowbar
activated again.
The electrics are basically just powering the radio, transponder and electric
turn
and slip so not using much power.
I reset a couple more times but sooner or later the voltmeter will suddenly
spike
and the crowbar trips. I reset as I throttled back during descent and all was
well for the rest of the flight.
I can only assume that the regulator is the problem. Has anyone else experienced
problems with the Rotax regulator.
Any recommendations?
Regards,
Martin Tuck
