Rotax 912 Voltage regulator

I agree with Dave. There has been a lot of discussion on this forum as well as other groups regarding Rotax and the Ducati regulator/rectifier. I believe the most common general consensus is that heat is the most probable killer of these units. Your particular electrical load and the location of your unit may be fine for allowing it to have a long life... I wouldn't replace it until, or if it fails, IMO.

I just carry a spare Ducati regulator in the plane at all times. It is not that expensive, is small and compact, and is easily replaced with very few tools in the field (at least in my airplane). I did have one fail at about 500 hours.

That's a really good idea for the emergency kit.
