Vintage 2006 Raymarine E120 Classic MFD and ST8002 Auto pilot lower and upper helm (upper slave). (Yes I know they are old but all in working order until yesterday)
Just started getting intermittent "No Data" error when using AP on "Auto" (not Track). AP unit operates for one minute to 30 minutes at a time, but intermittently as I ultimately get the no data error. All connections appear tight and both the AP and MFD display a similar heading at least initially when I turn on AP. I did notice that the no data error occurred once they deviated significantly after a few course changes (a few degrees). I historically recall them being relatively close, being within 4 or so degrees unless currents or wind caused "crabbing". Could it be the fluxgate compass on the AP "hanging up" or somehow malfunctioning? Any ideas based on your experience? Any testing protocols you can recommend for further diagnosis? Thanks.
