Raymarine ST6002 Troubleshooting

[sketchyMcG]

Hi Everyone,

This is my first post here and I'm hoping someone can point me in the right direction. I recently bought my 45' Dufour 12000ct and I'm in the process of emptying my bank account into said boat to get her seaworthy. A major source of my most recent frustration is the autopilot . When I engage the autopilot the boat either turns hard to port or hard to starboard, or it doesn't do anything at all. It does not respond to changing the course (+10 or -10) on the control head. I have gone through all of the setup again in the commissioning guide to no avail.

I know it's a longshot, but I wanted to see if anyone has had a similar issue with this type of pilot. My next step is to waive the white flag and call an electronics guy, but I'd love to save the $150 an hour if its an easy fix (doubt it). Here is what I know about my system:

Raymarine ST6002 Controller
Raymarine S3 Core pack
Raymarine M81121 Hydraulic Pumpset
Raymarine C80 Display

Thanks!

Googling Raymarine ST6002 shows there have been previous threads on the forum - so maybe look there first to find contributors who know your system?

I have noticed a lot of Raymarine fluxgates on evilbay whatever that might imply.

Does the autopilot's response (hard left, hard right or nothing) depend on where the boat is pointed? If so check for something located near the flux gate compass which might be interfering with it (loudspeakers, metallic objects etc).
