Autopilot malfunctioning

[jeffhughes88]

Makes sense but I've checked all wires end to end using an ohm meter, including the 4 channel wires. All of them show connectivity from the DB9 connector that plugs into the SV-net hub all the way to the butt connectors that connect to the servo. See photo. Tonight I powered everything up and switched to the SV-Net admin screen so I could see the state of all SV-Net devices. Tugged on all the wires at the butt connectors while watching the indication on the 5600 to see if the b-channel came to life. Didn't happen. Also tried wiggling the connector that plugs into the SV-net hub. Again, no change in status. I've taken the cover off the db9 connector and everything looks good. And again, I've tested from the pins on the DB9 all the way to the servo. Is there any kind of diagnostic test I can run to check the servo?
