The landing brake panel LEDs only indicate what polarity the voltage is going to the landing brake, not that it is actually up or down. After having the console switch fail to raise the landing brake and high CHT's after taking off, decided to add a position sensor. I used D37 P20 and configured it as the "Flap" sensor. It took some pecking around in the configuration and found I was missing details in the EMS hardware calibration screen. Adding 0 and 100 for the flap position resulted in widgets that displayed meaningful info. Alternatively, I could have used the VPX for flap control and maybe will later. The 10K 100mm potentiometer needed a +5 volt supply, so I mounted a 4 position terminal strip and connected the EMS white/red (+5 supply) to it. It now feeds the Hall Effect ammeter and the flap position potentiometer.
The AP roll servo was coupled to the aileron torque tube in the hell hole. After a couple years, the rubber had hardened and was slipping. The servos failed calibration as a result. I opted to move the servo to the rear passenger knee area under the arm rest, near the bulkhead where the torque tube bearing is. The challenge was to fabricate a bell horn for the torque tube and mount the servo.
I'll post photos and more details later.
