I have a master, avionics master, and autopilot master. Normally I do not turn on the autopilot master until I need it. Today after flying under the hood with the autopilot I turned off its master as I was not going to be using it again. My CFII asked me to turn it back on and it did not come to a ready state.

The Trim Down light was illuminated and nothing else. It did this once before a year ago and after shutting everything down, it worked fine again. The common factor was that it was very cold < 10°F.

Any idea what this error light means? There is nothing in the S-TEC 30 book about it. I am flying tomorrow and will see if it comes back to a ready state.

I also may have turned it off without first disengaging it. I think I disengaged it, but am not 100% sure.
