How to get Yaw Damper switch to stay on?

[SteveKane]

I'm relatively new at the F28, with about ten flights logged. I'm trying to figure out what conditions are necessary after engine startup and before RW lineup to get the Yaw Damper Switch to stay on. All hydraulics are in the green, all warning lights above and on the left panel are off. Eventually it seems to stay on, but I'm not sure exactly why. I've tried a few combinations of things (APU on or off, etc.), but haven't found a pattern.

If helpful, I can post a video of this and pan throughout the cockpit to show switch/light states, etc.

Disclaimer: I'm using Spad.Next to control a fair number of switches via LVARs on my hardware.

DIsclaimer 2: I'm on FS2024 SU4 Beta.

UPDATE: I turned off state saving and did a Cold and Dark from the tablet, and now the problem seems to be fixed. I'll guess some state value got corrupted, perhaps related to my SPAD tinkering. I'll report back if this recurs.
