Problem with Raymarine ST4000 Tiller Pilot

[mattyc]

Here is the issue. I turn on the pilot, hit auto and after about the 10 seconds the tiller ram starts extending in small increments until it is fully extended and then it continues to try extending. I have 2 of these pilots and they both react the same way so I'm assuming the problem is in the control head ot the compass. Any suggestions?

I should add that this boat is a recent purchased and it is on the hard. Is the fact that boat is on land have anything to do with the malfuntioning pilot?

Yes. Your tiller pilot is trying to steer a solid object that doesn't move :-) Also, you have to go through the configuration process the first time you are on the water with it so it can circle the boat and calibrate while motoring slowly. Instructions should be easy to find. Good luck.
