When I go into auto the rudder immediately turns hard to starboard and the motor flicks on and off. It then seems to flick between 10 and 20 degrees. It also seems that on the port side the rudder reference shows it as about 5 times what it actually is. On the starboard side it is 10 times. I know this from another rudder indicator.
