Hello. Im having a no rudref message on my st6002. I am suspecting my m81188 linear rudder sensor. Wiring is good from the sensor to the board. I cant find any spec on how to test the rudder itself. Do i use the same resistance spec as a rotative rudder sensor ?

A. Yes. Please click

Thank for your help. I did the test ; and transducer is not within specs. Since the m81188 seems to be no longer available, is there another part that would be a direct fit to replace it ?
