Hi everybody. Maybe somebody can help me out.
I have a PA46 with a autopilot KFC-150 installed. I have a intermittent, occasional problem with the autopilot. After staying for sometimes on the parking, the autopilot fails the startup test: the trim indicator fails and the autopilot disconnects.
After resetting the breakers, the problem persists. I have to fly the plane manually.
This is how it goes:
The avionic specialists from Piper have spent quite some time on fixing this mistake, but no success. The wiring and servos are Ok. The autopilot itself was tested on a stand: no mistakes. The HSI and AI were tested as well.
I appreciate any comments or advice to solve the problem.
