Alan,
The last page of this factory link has a basic wiring diagram.
http://www.europa-aircraft.co.uk/upload/CBM%20-%2025%20-%20ELECTRICAL%20SYSTEM.pdf
It sounds like your Europa may be wired similar to this. You certainly have the
optional battery isolator (master relay). What isn't clear is how your voltmeter
is connected. By this diagram your voltmeter would indicate only if the
master is ON and the instruments CB is ON.
When you have the Master OFF and the Gen ON, there is no 12v for the Ducatti regulator/rectifier.
Lead C of the Ducatti needs 12V to operate the internal electrical
circuitry and also to sense the system voltage. Without it, I'm not
sure what the indication would be.
As stated before, at 2000 rpm the voltage will be low. The Rotax is NOT an alternator,
it is a DYNMO. It's output voltage is dependent on the engine rpm and
it is quite low until the rpm is above at least 4000. 5000 rpm is better.
Surely a LAA inspector can help you determine how your Europa is wired and what
the problem is.
There may be no problem, you just need to operate at 5000 rpm. As Brian pointed
out, be sure there is a good ground connection from the case of the Ducatti
to the aircraft ground. Also be sure all the ground connections are secure, especially
from the battery to the engine and to the system ground.

Actually, change the sentence about the voltmeter. Your voltmeter would only operate
if the engine instrument CB is ON. It will show battery voltage only if
the Master is ON.

Hi all,
Any advice on routing the antenna cable and trim wire from tail to cockpit?

If you plan on using a copper strip comm antenna as Europa suggests, it will be
on the starboard side of the fin, so run the antenna cable on the starboard side
of the fuselage to the rear. Run the trim motor cable on the opposite side
to minimize the chance of interference from the comm antenna.
