I upgraded to v. 8.71 and everything seemed to work properly - but then I noticed that my pitch trim position indicator was wandering back and forth with no apparent rhyme or reason. Autopilot checks out and operates properly, as does the autopilot trim function (i.e., GSA 28 controlling the Ray Allen elevator trim servo), and when powered up on the ground the trim indicator is steady and then moves appropriately when trim is actuated.
Once the engine is fired up, though, trim indication begins to move around, and continues to do so in-flight, regardless of autopilot being engaged or what mode it is in.
I have not disturbed the trim system in any way that I can think of, the upgrade to v. 8.71 is the only recent change. The indicator is driven by the GP1 output from the GEA24.
I'm going to head back to the airport this morning and go through all the LRU and configuration settings yet again, just to see if something changed with 8.71 and I need to reconfigure - but I would sure appreciate any insight from the collective mind to help me chase this down!
