I am looking for someone to help diagnose and repair my Raymarine Autopilot
. Can you help?
Course Computer 400, ST8001 Autopilot Rudder
I am doing a new installation
of a used Raymarine
ST8001 Autopilot with a M11805 rudder
reference unit (RRU). I have no reason to believe that anything is wrong with the control unit, but when the autopilot is turned on the rudder display indicates the rudder to be in a “hard over” to starboard position. No error message is displayed. Movement of the RRU causes no change.
When the RRU is disconnected, no error messages are displayed.
I have checked the resistance of the RRU and the device checks out to specification. I have switched the Red &Green leads to no avail. (Interestingly, the Commissioning Guide suggests that if the resistance is out of spec, to have the unit repaired. It does not say what to do if the resistance is in spec, i.e., the unit is good.)
