Good morniing. I have G1 SR22 with a STEC 55X autopilot that is not holding a heading. The trim motor was replaced as it was thought to be the only issue. I have two G5s replacing the Attitude and Heading indicators. The tim works fine with the trim button on the yoke, and the autopilot climbs and decents just fine. My local Cirus service center is stummped. Any advace would be MUCH appreciated.
I had started chasing down issues with my 55x in my G1…and ended up just biting the bullet and putting in a GFC500 with all new servos. And i LOVE IT. Yes it was expensive but since you already have G5s you’re halfway there…sorry, not really an answer to your question but that was my experience.

Have you checked the turn coordinator?
Ouch… $$$. Thanks for the info. I’ll consider this a last resort.
I have not. Thank you, I’ll give it a look.
