There is one difference and one "clarity" issue. First the clarity. You must ensure that the regulator case is connected to earth. If not it will not work. Secondly, the .dwg file gives no indication of the function of the "L" connector of the regulator. It is in fact for a alternator fail waring lamp which should be connected across L & C. The Europa diagram shows it as a 12v 3w bulb. The diagram for the Europa can be found at http://www.europa-aircraft.biz/pdfs/buildersmanuals/CBM-25-ELECTRICAL SYSTEM.pdf Page 109 of the 912s installation manual also shows the alternator warning light.
