my boat is a Hunter 2002 356. The auto pilot has been working pretty good in light wind and calmer waters for years. However all of a sudden it just wanders even with no sails and flat water. In addition I notice that the compass reading does not agree with my mechanical liquid filled compass. The Raymarine has always been a couple degrees off but now it’s way off always. I always set the rudder gain to 1 and the response to 2. So I called Raymarine. Of course they no longer service this unit and no parts available. The tech believes it’s the fluxgate compass. He provided voltage readings to test with. I have not done that -yet. But just in case I searched for a fluxgate compass for my model on eBay with no luck. If anyone can help me here that would be so appreciated.
‘I need first to know where the fluxgate compass is located on my 2002 356. And I need to know if the st4000+ has a reset. Anyone has experienced this problem please share what you did to solve it.
