There are two batteries, A and B. A preflight check of both batteries is
required. Battery A is the normal ship's battery and B is dedicated to
running only the FADEC in the case of alternator failure. The switchover is
automatic but can also be accomplished manually. Somewhere in my notes is an
indication of how long it will power the FADEC, but I can't seem to find it
just now.

Liberty XL2 has the Continetal IOF 240 with FADEC. Would the engine run if
the batteries failed? It does not have a magneto. Would the ignition
system
run off of the alternator? The salesman at Sun-n-fun had no clue. Does
anyone know?
