[TG] SPX30 hard over on auto activation

[Pcbeachbroker]

I have sent my SPX30 unit in twice for testing. The Raymarine techs say there is nothing wrong with the unit. I have replaced both the flux compass and rudder reference. I have set up and tested the rudder bar on my ST8001 head. I am using a type 1 linear drive unit. At the dock when I press the auto function, the rudder immediately goes hard over. If the rudder is slightly to starboard, it goes hard over starboard and if is slightly to port go hard over to port. I tried to do a sea trial calibration but never passes the “swing” calibration. Any suggestions? Thank in advance
