I agree we want guaranteed and/or redundant power supply to at least one 914
fuel
pump, but I can't find actual data to class the reg as very poor, though.
There are anecdotal reports, but FAA's Service Difficulty Reports -- as as
voluntary
program it's a database of anecdotal reports also -- shows no
alternator/regulator
failures. It does cite other problems, many familiar in Rotax service
bulletins.
A reasonable issue is heat, so I've mounted the regulator in the tunnel (have
tri-gear),
rather than in the the engine room.
