Brief Description:  Dynon wiring

While I haven't made an entry in several weeks, I have been working 30 minutes here and 30 minutes there over that time period. I have been designing and implementing my wiring plans for the aircraft. I want to get as much done as possible before riveting the aft section of the aircraft and the instrument sub-panel.

What has been finished is the wiring for the network cable. There is a net hub just aft of the baggage compartment. I have the network cable, the data wires for the roll servo and the data wires for the pitch servo connected to this hub. Tomorrow I will be running the wiring for the ADAHRS unit which will also plug into this network hub. The network cable will connect to a net hub that will be mounted on the sub-panel.

Dynon does not want the power for the servos to run over the network cable. So I have pulled those aside (image 2) for the pitch servo. This terminal block allows me to pull the servo for maintenance (hoping that never happens.) These three wires (black ground, red, power and yellow interrupt) run forward to a terminal block under the passenger seat. There are limited openings for wires in the center section. So the same three wires from the roll servo will join the pitch servo at that terminal block and one set of power and ground will go forward. The yellow wires will be joined and run to each stick for disconnecting the autopilot switch.

I also bonded wire tie cradles to the sides of the channel running between the seats. This will give me lacing points to bundle together several different sets of wires neatly. AC 43-13 calls for one every six feet, but mine are about every 18 inches. The elevator push tube also runs through that channel so I want to ensure there is not chance for entanglement.
