- a rudder which has been commanded to rotate to a greater angle than is physically supported by the vessel (ex. rudder stop encountered, steering ram fully extended ... adjust rudder limit configuration setting to the lesser of 30 degrees or 2-3 degrees less than the hard over angle.

Did the check we did above rule this out?

- failing rudder reference transducer ... Please click here to view a FAQ addressing how to test a rudder reference transducer. Should the old rudder reference transducer not have been replaced when the Evolution autopilot was installed, then it is recommended that it be replaced with the rudder reference transducer included with the ACU-400.

I have done this check and all appears ok. Its the rudder transducer that came with the boat.

- for hydraulic steering system, air within the hydraulic can cause the system to become airbound ... bleed the hydraulic steering system.

Will check this.

- drive FET failure within the ACU or legacy autopilot course computer ... this is an all or nothing failure. If the ACU can turn the rudder in each direction (i.e. voltage is being issued to the motor leads when steering in each direction is commmanded), then the ACU or legacy autopilot course computer would be considered to be operational. Send the ACU or legacy autopilot course computer to Raymarine’s Product Repair Center to be bench checked / serviced.

It has been working flawlessly for years.

- failure / dead spot within drive unit ... have the drive unit tested / serviced.

- incompatible third party drive unit ... replace with appropriate Raymarine drive unit. Had this drive unit previously been successfully used underway with the EV-400 w/o producing a drive stopped error, then you may be somewhat assured that the third party drive unit is compatible.

Yes as above I am satisfied over the last few years they are compatible.

It has not re faulted of late...will report back.

Thanks.
