Thanks for the suggestion, Ernest. Yes, my switch will stay in Alternator
position even with a diode - because even a diode can fail and I really
dislike repeating incidents due to the same cause {:>)

When wiring up the diode, it should be fairly simple to drop in a large
value mylar capacitor to conduct the noise. My experience with
electrolytics is that they can be poorly made and leak. The mylars would
be more robust in the environmental extremes of an airplane.
In any case, I thought the diode was just for a backup. The switch would
stay in the same position it has always occupied, so noise would be
absorbed by the battery as it always has. The EC2 would have to be on
the battery side of the switch, which would make it even more noise
isolated when hidden behind the diode.
