Is it unusual? Raymarine Wind instrument

[Jabamusic]

Recently had to remove my Raymarine wind vane from top of mast (rusty after too many years of neglect ) for some TLC. Once sorted, replaced it and she is now spinning merrily.
However wind direction indicator is now 180 degrees out.

Now, I am aware that recalibration/reorientation is required (turn boat 2 x 360 degrees) - which I have done, but I sort of expected that it would then start pointing in the right direction !!

Reading the manual states that once the 360's have been done, I should then sail head to wind (!) and adjust the heading indicator using the associated buttons on the head unit- my question is, is it likely that I would have to adjust it by as much as 180 degrees? or is something else wrong?
As always your thoughts, ideas and expertise very welcomed.

Sounds very unusual.

I remove mine every winter and replace in the spring. Have done for 10 seasons with no problems at all, no recalibration or correction.

Can't help with a solution but sounds like something has gone amiss internally.

try swapping green & blue either at the rear of the display or at the base of the mast if there is a connection box, then calibrate.

I only removed the masthead fitting - no wiring was altered/removed?

It is possible the grub screw locating the vane onto the shaft is loose or missing, that would allow the vane to rotate on the shaft, altering the alignment. Or while giving it some tlc, you have miss-aligned

If that is Ok, then its a new masthead unit.

180 deg out is uncommon but possible.
It has happened to me. Just re calibrate as per instructions.

Grub screw - now there's a thought...............!!
Thanks for responses. Hopefully I can sort it. Otherwise I'm looking at £250 :-( I think.

Misaligned Starfire? That is the bit I'm confused about. How can you misalign it?

When I replaced my Raymarine wind vane I did the calibration after fitting while the vane was held stationary pointing dead ahead - worked perfectly. It was difficult to turn the boat as it was aground at the time. It does need two people though if you do it that way.

Had the same problem when I replaced my Raymarine wind vane having had it repaired following a bent shaft. It was exacly 180 degrees out. Corrected it using the manual adjustment and it has been fine since (over two years ago).

The shaft of the wind direction sensor has a flatted side. This should face the little screw that locks the vane to the shaft. It's fairly easy to mis-align this as the very moment when you assemble the vane to the shaft.
It can be prevented by setting the locking screw not too loose so the vane will not be able to slip over the shaft unless the flatted area faces the screw.

Thanks aluijen.

I will re-read this when the contents of a nice bottle of red have become a sadly, long forgotten pleasure - then it will make perfect sense and I will know exactly what to do !

The later versions have a "D"shape with a vertical screw. I have just had one repaired and am waiting for thr rigger to fit it while he does some other work aloft. I sealed the screws with a dab of sillicone sealer to stop them coming out, and to allow them to be removed should it be required. My older model masthead unit has the fittings you describe, and currently reads 180 out. So far we have not been able to recalibrate, hence the reconditioned one. Fingers crossed............

What exactly did the "TLC" consist of? Could you have removed the little round circuit board and refitted it 180deg out? Or even the plastic vane?






Edit sorry didn't see latest overnight updates - so I'm repeating again...

The vane was removed, but not the internals ie circuit board. Yes, it is possible that it was replaced back t' front ! Am off down to the boat now to have a look.
