>> The voltage hovers around 14.5v with
little load and drops to 12.5
or so with a load at
cruise
Randy,
I have
had a slightly similar situation on two occasions over my 1500 hours on my
Lancair 320. I am using the split style Cessna master switch in my
panel. I just replaced this switch, again, and my voltage fluctuations
disappeared. If you are using this switch, I suggest you try wiggling the
switch around to see if it temporarily fixes your problem (mine did). If
it does, you might consider replacing it ($26 from ACS). I don't
understand why these style switches have this problem. Perhaps corrosion
and/or pitting is a problem. For some reason, I only experienced this
problem in-flight. Shutting off all of my electrical equipment during my
in-flight diagnostics, however, did not fix the voltage
variations.
