NEXUS Autopilot 1510 summary of known checkpoints
All Autopilot systems are complex systems dependant of a number of transducers and control algorithms why faultfinding needs to be done carefully to lead to correct remedy.
Checkpoints:
Power:
It is essential to Power the Pilot servo and the Pump motor to get current enough without risk of voltages drops.
Wireing can be effective by using Relay to get shorter length of cables.

In a system without relay the Nexus system should never be powered up later than the AP Servo.
To avoid ”backdrain” of current do not connect the Green wire (+12V) from the Nexus system.
