Open Question

Autopilot not getting data from RFC35N fluxgate compass.

Trying to install a brand new Simrad auotpilot system as supplied in a package. (Everything ok - hydraulic motor working rudder, rudder sensor, etc. but "Missing compass data" error message on AP 25 screen). Compass sited and in place correctly with a direct 13v supply from battery...wiring instructions ambiguous in RFC35N leaflet and this model compass not referred to at all in Simrad Autopilot manual's installation instructions. Green NMEA input and output LEDs on computer flashing...
Can you please advise how to connect compass to computer. Wires in compass are grey, pink, yellow, green, brown, white.
I have no other compasses or other instruments connected to this system.

Raymarine smartpilot x-5. The fluxgate compass is some 45 - 60 degrees out from the boat compass. I have tried to recalibrate but this does not solve the problem. Any ideas?


First of all - is the boat compass correct? How does it align with COG? Secondly, do you have a magnetic field that interfere with the fluxgate? To test for this you can use the compass on your smartphone or a handheld compass, move about in the boat and keep the phone/compass aligned with the keel. If the heading drifts in the area where you have your fluxgate today, move it.

I installed a Raymarine compass sensor in a GRP sailing boat underneath the chart table at least 50 cm away from metal and magnets. It is connected to a SP X-5 computer unit and a ST6002 autopilot...


If I were troubleshooting this, I'd manually adjust the orientation of the compass sensor until it matched the true heading. Once that was done, I'd move it side to side to ensure it's changing in the correct directions. If not, the unit could be upside down. Let me know how this turns out.

compass needles are affected by iron objects and can also be affected by field magnetism generated by current flowing through a wire .Bilge pumps , winch motors are heavy current drawers and they could affect the compass operation
while the voltage is low the field of the magnetism around the wire can influence the compass heading so check for any electronic apparatus wiring close to the unit ( radio , radar etc
it may be necessary to run the powers wires in an insulated sheath ( like coaxial cable or other insulated power cables) around sensitive equipment
talk with marine equipment installers to get better ideas as to prevent interference with the compass

I have 1994 Carver with Simrad AP which I would like to update as economically as possible. How do I do that?


The original hydraulic pump, rudder reference and compass should work with the newer systems so you can look into buying a new course computer and display in seperate pieces. You may find however that new ssytems are packaged in such a way that it will be the same price to just buy a complete new system. Whatever you decide, it is worth a phone call direct to Simrad to be sure that everything is compatible before you spend any money.

The S1G display occasionally shows no data. The autopilot works fine for hours then fluxgate seems to hang up.


Try to borrow a computer unit to detect if the fault is in the computer unit or the display unit
