Hey - I am having issues with my Plane Power alternator, and I'm not sure where to start trouble shooting.
When I start the plane the alternator comes on line, voltage on the main bus is 14+ and everything appears to be working fine.
However, as soon as I go full power for take off, I am getting an alternator short alarm from my VP-X system. I have tried to reset the alternator in the air (under relatively high power) and it trips off as soon as it resets. Once I am on the ground and back at low power, I can reset the alternator and it doesn't trip.
Nothing has changed in my electrical system. My alternator is 6 years old with about 275 hours. If the alternator is bad, I'll replace it, but I just want to avoid spending $500 on a new alternator that doesn't solve the problem.
So electrical experts.... what is the best way to trouble shoot this issue to figure out what is going on?
