Autopilot Pitch Servo Installation Completed

Made it out to the hangar yesterday and completed the instillation of the autopilot pitch servo motor. The pitch servo was mounted in the previous work session but the noise filter and wiring along with the F-1292 pitch pushrod assembly that attaches to the WD-1210 control column were left uncompleted.

The autopilot pitch servo motor receives a noise filter capacitor (assembly ES-00103) which is wired to the red power wires … two wires connect to the red power wires and a third wire attaches to a ground point obtained from the seat rib that the autopilot pitch servo is mounted onto.
The ES-00103 noise filter capacitor assembly will attach to the autopilot’s pitch servo motor wiring.

Installing the ES-00103 noise filter capacitor is easy … there are just two spade connectors to attach to the wiring and a ground wire with a ring connector which is attached to the seat rib along with another ground wire from the 9 pin Molex connector.  Both the noise filter capacitor and Molex connector get secured to the body of the SV32 servo motor with wire ties. The most time consuming part of finalizing the pitch servo wiring was figuring out how to wire tie all the wires so none of the wires were chafing on any of the metal surfaces such as the seat ribs or body of the SV32 servo motor.

I still need to silicone the noise filter capacitor for the fuel pump to the bottom skin … so I think I may also add a dollop of silicone to the pitch servo motor noise filter capacitor to prevent it from possibly moving under the wire tie. We have some warmer days coming so this may be a good time to get that task out of the way.
