Hi Roger,

the capacitor is optional, but highly recommended - might also take care of your static issue.

Betreff: Re: RotaxEngines-List:Electical System 912S



I've a 912S on a Savannah aircraft with a Microair 760 comm. Comm works static free 5X5 with engine not running. With engine at idle I'd rate it as 2X5 as RPM is increased so does the radio static. The radio has a profesional made harness by a reputable shop. Looking at the electrical diagram in the Installation manual I notice a capacitor with a value of 22000mfd 25volts can anyone tell me if that's a required component or is it an option this part is not installed on my electrical system, Can antone advise, thaks



Regards,

RJ Roy

Hi Malcolm,


Don't fly it until you have this figured out.
You may lose an engine in flight.
It has to be your charging unit out put or the reg/rectifier. My bet it is your reg/rectifier. They go out more often than most charging system parts. It is easy to replace, too. First look carefully at the wires going into the reg/rectifier and see if they look burnt or very dark in color. You can take a volt meter and put this on the terminals to the battery and see what the voltage to the battery is, like you said it should be about 13.8V to 14.2V is normal. This may vary a little, but should be close.
