[LW11] different brand hydraulic ram
I have two ACU400 with EVO sensors driving two B&G type 3 hydraulic ram assemblies. I got these because a friend in the business could give me a good price.
I've had problems with autopilot hunting while connected to the rudder reference sensor. I've followed all trouble shooting tips and have been unable to stop the hunting even with rudder damping set to "9".
Also, without the rudder sensors connected, I have been unable to perform the hard over test. I can get no more that hard over to mid point and the movement consists of steps rather than a continuous motion.
Are there compatibility issues between computer and rams? Should I replace the B&G with Raymarine units?
