Wo, this is the first I’m learning about this potential issue with the Edge Fuel Injected engines. The Rotax 912 engines have THREE power sources built right into the engine. 3 engine driven stators. Adding an alternator would be a 4th! In the carbureted models, there is 1 stator per electronic ignition and 1 to drive the main bus for cabin power. If the voltage regulator dies, I do not believe it effects the engine at all. Someone please correct me if I’m wrong.

Does the Edge EFI rely on the voltage regulator to be working? Are all the stators still in use? Seems like a bad idea to have a single point of failure in an aircraft engine.
