I need a Datamarine fluxgate compass for my old Datamarine Link 5000. I doubt I can find one. I need information about how to connect another fluxgate to the Link 5000. I have a Autohelm fluxgate with a five wire attachment to the Autohelm. I am sure two wires must be power. The Link 5000 has only two connections for a fluxgate. Does anyone have information about what the Link 5000 compass input requirement is, or what the Autohelm fluxgate output is?
