Brief Description: auto pilot, mic and phone jacks
Although I identified the pilot and co pilot headphone and jack cables when they were bundled into the service loop the labels ended up in the loop leaving four unmarked cable ends protruding. My multimeter went west so I purchased another one at Sears. The new one has a tone feature.
I used the new multi meter to identify the cables. I also identified the wires in each cable based upon where the attach to the jacks.
Pilot mic jack Tip white wire connects to J1 pin 34 on audio panel sleeve- white/blue connects to J1 pin 35 Ring red/white connects to J1 pin 33
Pilot Headphone jack tip red/white connects to J2 pin 16 sleeve white/blue connects to J2 pin 1 ring white connects to J2 pin 31
Co pilot mic jack tip white connects to J2 pin 33 sleeve white/blue connects to J2 pin 34 ring white/red connects to J2 pin32
Co pilot headphones tip red/white connects to J2 pin 3 sleeve white/blue connects to J2 pin 2 ring white connects to J2 pin 4
These cables were run to the back of the audio panel but not pinned or connected. That will be a later work session
Dick Isherwood assisted tonight and remained until 11pm.
We reviewed the GRT autopilot pitch servo installation instructions which do not exist. GRT said to look at Dynon and Trutrack for the install info because their servos are identical. Dick and I determined how to mount the unit. The servo will be on the port side of the aircraft. It is better to run the wiring down the port side because the starboard side is pretty much full.
I removed the wiring I had run up the starboard side and re ran it up the port side. We rant it through the service loop and prepared it for connection at the GRT unit. Then we reviewed the documentation and realized that the black ground wire did not need to be run forward and could be connected near the servo t
