Close as I can get to your model number. See attached link

I have one right here. It covers the RPU80, 160 & 300. It's $15.00 plus shipping. Call me at 410-228-7335 if you're in the U.S.

Try and turn on the unit at the J300-40 pcb by using a test light one end to gnd and going to the ap35 interconnect and touch the test light to each pin or until you hear the unit start up.

Yep, if rudder calibration values are OK, then there is a real problem with calibration, it can be a mechanical problem or a faulty rudder feedback unit. Follow procedure at page 93 of user manual :
AP35 Autopilot Instruction Manualto troubleshoot the error, if you cannot get rid of the error message you may have to replace the rudder feedback unit or to have the unit inspected by a technician.
