Thanks for the video! First my wind direction wasn’t working. Then my speed went out as well. Several days later I discovered your video and checked my voltages. Seemed to be in line with yours . I checked the display and both were working. I’m now assuming I have a bad connection either at the display (gonna install new bayonet connectors) or at the mast head itself. I think the masthead shouldn’t be bad as when I installed it a year and a half ago I put dielectric grease on the pins and made sure it was properly tightened. I hate intermittent problems! LOL. P.S. I’m in Sarasota Florida and during the last hurricane winds speed reached 106mph.
The chip you recommended does not appear to be carried by company any more. There are similar chips with different model numbers. Don’t know enough to order one that I know is correct replacement.
Fantastic video! I have the same problem. But I can't find the MLX91204KDC-ABA-002 anywhere. It seems to be discontinued. Can you suggest a currently-available replacement? I've looked at a lot of similar chips, but there are at least 6 from the same chip maker with slightly different specs. Thanks so much!
Hi, it's been years since I did that, and sold the boat a couple years ago. I don't have any recent knowledge about the ICs avail. But I would think if you emailed Melexis and asked them they would probably have an updated part avail through distribution. I do recall buying 2 of the chips figuring I might as well buy 2 if I screw it up. LMK if you strike out and I'll look through my parts.
@@peterowens4770 - Thanks, I thought you might be a real electronics nerd and could just look up the current equivalent. :-) But your idea of emailing Melexis is great - I'll do that!
Thanks for the video. We have lost wind speed although retain wind direction. Regarding the chip you replaced - does that correspond to IC4 in the instruction manual - which says "Do NOT attempt to replace or otherwise disturb IC4"?
Not sure. There are 2 hall sensors, the wind speed sensor is on the bottom of the PCB. Its not the same IC as the one I listed as the part number. You'd have to disassemble and verify. If the board is broken I don't see why you wouldn't at least attempt a repair if you're confident in your soldering abilities. Cant hurt.
It unscrews. Technically you don’t have to remove the vane but I did to get enough leverage on my 12 y.o. vane. When I did get the cap off a tbs of water spilled out. Methinks this may be part of my problem.
Hello I need to repair my wind vane also I have the proper voltage out of the unit But not returning from the vane Wind speed also quit should I just replace the whole board I can replace the Hall effect chip but I don’t know the chip that controls the wind speed. Do you happen to know what that is?
Hi Mike, I'm not sure I did not replace the wind speed hall effect sensor. You could disassemble and check the IC for any part number details. No guarantees it will work or if it is something else. I think you can find the circuit board in England or maybe on the Bay when I last looked.

Great video. Can you diagnose and repair my 1) Raymarine masthead with wind speed not working and 2) Boat speed I50 where screen has failed
Looks like that IC is no longer manufactured and I haven't found a direct replacement yet. Any thoughts?

Ciao se volessi comprare la schedina, sai dove potrei trovarla? Grazie
how do you open the housing ?
It unscrews. Technically you don’t have to remove the vane but I did to get enough leverage on my 12 y.o. vane. When I did get the cap off a tbs of water spilled out. Methinks this may be part of my problem.
Thanks for your answer mine is really stuck and would like to know it unscrews before I use tools
Hello
I need to repair my wind vane also
I have the proper voltage out of the unit
But not returning from the vane
Wind speed also quit should I just replace the whole board
I can replace the Hall effect chip but I don’t know the chip that controls the wind speed. Do you happen to know what that is?
