Hi Jan, I saw a video of the Plane Power/Hartzell guys from Oshkosh this year, and the PP expert said something to the effect of "I don't know why you would want to have the alternator on during the starting event." I changed my process to turn on the alternator after engine start based on this statement.My Plane Power also failed this weekend after 830 hours of service. Happened away from base but for some reason I have packed my spare alternator for the trip. I did not have the time to do fault finding yet.
Slight thread drift - I have always started and then switched on the field switch in order for the alternator to start charging. Is there any evidence or data out there that might suggest that one should have the field switch on before starting?
When shutting down, I leave the alternator on until after the engine stops.
I believe it was this video:
