I figured I would share as this was not anything I had seen before nor had any of my hangar mates.
Symptoms - Over past 5 flights, electric DG would occasionally throw up the flag and the DG was not holding heading for very long when the flag was hidden. Two times it would not start right away when avionics power was energized. This weekend, nothing I could do would spin it up.
Well, I figured it was time for me to decide on the G5 or the AV-30 as I have been kicking that decision down the road for months.
On a whim, I decided to check to see if the breaker was working since I was not able to even get the littlest noise out of the DG. The breaker has never tripped since I have owned the plane. Voltage on the line side was 12.4v and on the load side 2.8v. I cycled the breaker a few times and still just below 3v.
I have seen breakers fail both open and closed, but never in a partial voltage state.
