I recently bought a boat
fitted with a ST4000+, wheel
drive and rudder
position sensor. On the delivery
trip home, the boat
was oversteering a lot but manageable. I assumed at the time that the rudder
position sensor was dead.
Finally got around to looking at it (it was not a high priority item) - checked the volts at the control head
- return from the sensor seemed fine 1.5v hard over one way 2.5v straight and 3.5v hard over the other way.
I went into user setup, changed the display to rudder bar. Rudder bar is now shown on auto, but not on standby, however the display does not move, it just shows the rudder dead center regardless. I read somewhere that switching to tiller pilot, then back to wheel
pilot could get the control head
to check for the position sensor.
Went into dealer setup. I see CAL
?, but cannot move from there. None of the keys have any effect. According to the manual DISP steps through the options, +1 and -1 select values. All keys beep when I press them, and work
After a few seconds, dealer setup times out, and puts me back to standby.
Oh, and it is Version 14 - I'm guessing that is a software
