From: "h&jeuropa" 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.

From: "h&jeuropa" 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.

Run the trim motor cable on the opposite side to minimize the chance of interference from the comm antenna.
