I already talked to a mechanic. His first thought was to continue

doing to the avionics. (If the voltage is spiking low it could also be
spiking high.) After I explained this to him, he changed his tack and
said probably the first thing to do is to pull the cowling and check for
loose connectors, bad grounds, etc.

I'm just not sure how much I trust this guy.



I can see why his attitude is not inspiring confidence. However, it is
quite possible that he is right in thinking the problem might be a faulty
ground. The first thing I'd check would be the battery ground connection.
Could also be an intermittent master switch.



Oh yeah, doing a solid connection check is a sound first step. I just
didn't like his "wait until it breaks" attitude. I didn't think of a
master switch. Good suggestion.
