The regulator has functioned fine until tle last couple of flights, when I noticed that the voltmeter was flicking up and down once or twice a second around a mean of about 13 volts. Then today just before shutting the engine down, I noticed it was reading 16 - 17 volts on idle, and when I increased to 300 rpm it went up to 18 volts, with the battery ammeter showing a small charge (half amp). So I suut the engine down and looked under the cowl, and superficially all looked well with the regulator and wiring. I didn't have a voltmeter with me, but will check the connections tomorrow. The regulator is wired as on the Europa diagramme, with the R, B+ and C leads all connected together and to the + terminal of the capacitor, and through the 30 amp fuse to the main bus via an alternator output switch. I'd be very grateful for any suggestions / comments from the pundits - does this have to be a regulator problem, or can any wiring or connection issues cause this problem? I'll check that I have battery voltage at the C terminal tomorrow, but the connections looked fine. Many thanks in anticipation, Keith Hickling, New Zealand.

During my annual inspection in April last year, I found some corrosion at the bottom of both carburettor bowls. At this time, the 912ULS engine was 4 year old and had 360 hours total, using mainly Mogas. This corrosion had produced some black particles (supposedly zinc oxide, as the bowls seem to be made of cast zinc-aluminum alloy) which could partially block the nozzles and prevent the carbs to work properly. I talked to the french Rotax distributor who said that they had never experienced such corrosion. After a thorough cleaning I reinstalled the bowls. This year I decided to buy new bowls for replacement during the annual. Surprisingly, I found that the new bowls were now nickel-plated, certainly for a reason: preventing corrosion! During the annual, I found some additional corrosion inside the bowls. As I had to also replace the 5 year old diaphragms, I inspected the piston and needle and did not find any corrosion on these components. Conclusion: remove, clean and inspect carb bowls at least every year as recommended by both Europa Aircraft and Rotax.

I took me a while... to simply discover that my ground connection to the battery was loose. The battery was not playing its buffer role. I understand you can see some current going to the battery, but there could be some connection to clean or tighten. Just my own experience.

My regulator has been mounted on the passenger footwell front inside the plenum providing fresh air via NACA to the air intake. So far so good, only 175 hours to date... Any other 914 data out there? P.S. Steven and Ian and Irene. It was very good to meet you all. I just flew over the Sierra from Sacramento to Bishop Ca (over Yosemite) showing a groundspeed of 175 knots level at 17,500'. Ok, there was a smokin' tailwind. And yes, I am having one heck of a lot of fun.
