Greetings all,
Anybody have the amp usage from the Rotax 912 ULS ignition? My analysis is pushing the 14 Amp threshold and need some good numbers.


I think I found my answer. The violet wire from the A and B modules are for starting, and the switches are grounded. So any power used would be during the start sequence and not normal operations. The alternator has seperate poles to keep the ignition isolated from the rest of the electrical system. So short of a total internal failure of the alternator, the engine should continue to operate even if the aircraft electrical system failed.
Does that sound correct?
