[C320-list] Autopilot Troubleshooting

[Paul Rickman]

If all this fails, I found that it was also helpful to be on the boat with the autopilot on, and call Raymarine.
In my case they said ship it to us and we'll try to fix it. I think turnaround was a total of five days.
All new touch pads and it works great. Totally rebuilt.

John-I have diagnosed a few Raymarine autopilot problems on my 2002 320. First make sure you have the settings correct from your owners manual for the autopilot.  It seems unlikely that improper settings would cause intermittent compass errors, but that is an easy 1 minute drill.  Your problem is probably a bad connection in one of the four wires connecting the autopilot control head to the fluxgate compass, a compass malfunction or something near the fluxgate to cause deviation.

You can check out if the fluxgate compass is working by looking in the Raymarine customer help section.  Last year I had a problem with my ST 4000+ autopilot and found a trouble shooting section on their website for compass troubleshooting.  I found answer ID 134 which deals with advanced fluxgate compass troubleshooting.  You need a VOM to check out resistance between the 4 wires from the fluxgate compass to the autopilot head.  I don't have the exact link but once found it gave very simple steps to make sure your compass in working.

I was able to eliminate the fluxgate as my problem last year using the above procedure.
