I have a Bristol 38.8, equipped with a Furuno FI 50 wind instrument, and a FI5001 transducer. Last year I had the mast removed and the boat rerigged. Before that work the wind instrument worked properly. After re-installation, I have not been able to calibrate the instrument to properly display the wind angle. The other functions (wind speed, etc.) work properly, and only the wind angle display function appears to be affected.
I have attempted to calibrate the wind angle by using the ALI function in the set up program, by putting the bow into the wind and adjusting to 0. However, when I return to the operating display, and regardless of the actual wind angle, the wind angle indicator swings to point to the stern of the boat. It will then function only - and arbitrarily- within approximately 30° of either side of the center of the stern, not corresponding with the actual wind angle on the boat. I have attempted to account for this by entering a 180° error adjustment, without success.
The marina has checked and rechecked wiring coming out of the base of the mast, and the color coding appears to correspond on either side of the junction box with the instrument. There is no NMEA 2000 or other intervening junction. I am told that it is impossible to mis-connect the fittings at the top of the mast.
Can you suggest any other solutions?
