Autopilot Wiring Planning

[mike_newall]

Just pre planning the wiring in our 10.

Skyview, Com, Txp, Knobs, 2 servos, PM audio panel.

Looking at power - I want to route the ADAHRS and both servos through a hub in the fuselage by the wing root. However, The connection from the hub to the Skyview won't want the power feed to the items as they will need a c/b. I have the Dynon harnesses for the servos, but am now wondering if the pos/neg get stripped away from the hub interface and run up to their own independent c/b's ?

The hub is not intended for power/ground use on the servo's. You'll need to split out the power and ground separately from the DB9 connectors, pin 2 for ground and pin 7 for power. See section 10 of the installation manual. Pin 3 should also be split out separately and combined with the other servos in parallel, and this is used for the autopilot disconnect and CWS signal.

That is what I thought, thanks. ADAHRS should be OK to power through the hub though - shouldn't it ?

Yes, you don't want the ADAHRS to loose power is ships power dies. The battery for the SkyView should power the ADAHRS or you will loose all your flight instruments.

The backup battery will also power the EMS, so you keep all your engine instrumentation.
