My question now is why you didn't get a failed AP warning on your EFIS. When I turn off power to my AP, I get a warning that my auto pilot servo failed. I wired each servo individually so that I could isolate each one separately and the warning would tell me which one failed if I turned one off. I read the Manual that if one servo failed, I could fly with the remaining good one. So when I turned off the power to one servo, the warning would tell me which one failed but both servos no longer operated. Whats up with that? Anyway, I think something is wrong with your warning system.
Morning. The answer is simple... unknown. Since this episode began, my HDX has made no mention of any warnings. It IS working, as I do get other warnings (oil pressure, etc). It could be because of settings done by the previous owner? I have been a 6 pack flyer for 40+ yrs, and this machine is all Dynon, and its taking me time to become acquainted with it. Learning slowly! Despite both servos not being detected, it never gave me any warnings.... just an absence of any A/P indications/menus. Actually, the servos didnt fail... they were returned to Dynon and functioned fine... it turned out to be likely the ring terminals at one of the C/B's. So, power was eventually the culprit.

If the servos didn't have power on screen bootup, then Skyview never knew they were installed in the first place. If they "were not installed" then obviously they cannot fail, thus no warning. In your case if you boot the screen with power on the servos, then the screen knows the servos should be there, and if one drops off you get the warning. In the OP's case there was no warning because the servos were never detected on bootup - it just means the AP is unavailable because there are no servos installed.My question now is why you didn't get a failed AP warning on your EFIS.

You could test this in your own system by pulling the power off your servos with the panel dark, then boot Skyview. If I'm right, you should not get any warning about the servos, and you should not have AP available.

Like I posted earlier, if I don't turn on my servos, my system will tell me they have failed in two ways. It will list them as failed in my warnings and also show them X'd out in my notification window at the top of the screen. It will also tell me which servo is not functioning. I can remove the warning by just turning on the power to the servo that's failed. I do it all the time. What I don't understand is that if I turn off the power to either servo, the servo that remains active doesn't work either even though the power is still on that servo. Another words, both servos have to be on otherwise neither one will operate and that is contrary to what the manual states.
The system knows what network has been installed because when the installer sets up the system, the servo network is identified in the system. You can see what networks are connected by going to system setup. (Hold down buttons 7-8) /systems setup menu/Skyview network/network status. If it has been installed, it will be listed and that it is operating correctly or not. If any network fails, it will indicate it not operating unless it was never installed and activated in the first place or for some reason it has some how been removed from the list. In the above case, it had to be installed properly because by fixing the lose connection, it worked.

Still once the servo's are lost from the configuration the Dynon system doesn't know anything anymore about any servo's and will never give you a warning anymore. So if at any point the system was reconfigured without working servo's then from that point onward you will never see a warning or failure being reported anymore.
