![]() Failing fluxgate compasses should be replaced with a M81190 Fluxgate Compass which may be ordered from an authorized Raymarine dealer. If all readings match those indicated assume the compass transducer is functioning correctly.Ī failure would be identified should any of the above listed resistances show an open circuit (infinite resistance) or deviate from the above listed resistance value by +/- 2 Ohms. Follow the above procedure for all the color combinations indicated in the test data table.Ĥ. Connect one multi-meter lead to the red wire and the other lead to the green wire and a reading as indicated in the test data table should be present.ģ. Disconnect the transducer from the system.Ģ. The following procedure should then be followed:ġ. Should the items referenced within this FAQ have been addressed and heading problems persist, then the fluxgate compass should be tested. not change or not be reflective of the rate or turn), then it would indicate a problem with the mechanical components within the fluxgate compass, necessitating its replacement. This condition may be verified by executing a slow turn at a constant rate of turn through 360 degrees while observing the reported heading. Additionally, as the fluxgate compass features mechanical components, it is possible that the fluxgate compass's moving parts may have failed in a manner causing them to bind. ![]() Please click here to view a FAQ addressing providing further information on this subject. The first part of troubleshooting a heading issue associated with a magnetic north seeking compass is to ensure that items capable of producing a magnetic field have neither been positioned nor installed within 3' of the magnetic north seeking compass. ![]()
