Thanks Dwight, I may have to do the same with mine? But I need to verify the volts outputting from DM1 and DM2. According to the service manual, they should switch polarity and pulse DC to power the motor. I had my steering pedestal off this spring and may have pinched the wiring somewhere between the pedestal and the aft cabin? Have to take some small jumpers w alligator clips to attach meter probes to troubleshoot. Didn't have those w me Sunday.

It does not work. The display is displaying and all buttons seem to work. Today it kept displaying XTE. I pulled the motor connection and read a short pulse of volts at the socket when I tried to change course through the controller. The motor surged for a while and stopped. It seems like the motor is OK. The display reads a magnetic heading and seems to function OK, but when I push AUTO and change heading, nothing changes except the display heading. Wiring problem? I have a wired remote that may be lying under a pile of sails, or a tool bag. Could that be causing interferance?
