My Autohelm ST4000 wheelpilot puts out incorrect compass headings. It hasn't been used in quite a while and I thought maybe the compass was stuck and might free up after some use but that has not happened. It does change readings but never correct. I have recalibrated but doesn't help. When I engage autopilot I get a message "no data". I am assuming that my fluxgate compass is bad and needs replacing. Any thoughts from anybody about this?

I would start by checking all the connections to the autopilot computer. The wires from the fluxgate compass are tiny and could easily come loose from their connection at the computer. Then I would go through the troubleshooting procedure to check the resistance readings for the different wire combinations of the fluxgate compass. I had a problem with mine and had to send it back to Raymarine to be repaired.

I've had the same problem. It comes and goes, but mostly works. I've already checked all of the connections. On the one hand, it is difficult to find a problem when everything is working. On the other hand, I'm glad that it works most of the time.
I'll be watching to see what you learn from others as it may help me as well.
good luck

Amazing
Well, I installed the "new" fluxgate I bought from Defender and it did the same thing, so I figured it must be the control head. I sent the control head and fluxgate to Derek at Breakwater Marine in Webster, Tx. and he checked it out and said nothing wrong with the control head, compass bad. My new compass was also bad so I had to order another compass. It arrived and everything worked great. Who would have thought the new compass would be bad also. Took over a month to work all this out, but working great now. Thanks for the interest.
