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.
