>Everyone seems to be forgetting that the 914 Rotax already has redundant
electrical systems. It has an alternator and it has a magneto that will
operate the fuel pump and minimal electrics in the event of alternator
failure. Lest we forget the battery which will usually (if you are aware of
the failure and conserve juice) outlast your fuel supply. <


It is only redundant provided that the battery is protected against
regulator failure. Single regulator failure can lead to total electrical
failure. Hence the use of a crowbar unit.
