Sitting in the marina planning sailing for tomorrow. Yacht was sailed last week by co-owner.

Its quite windy, so turned on instrument to see how windy exactly. It must be blowing 15-20 knots. The instruments show the direction correctly. The number of knots is showing 0.0 almost all of the time although did get to 0.4 or 0.5knots momentarily. Same number throughout the system ie on the wind display, the plotter and the multi-display

I have a 10 year old all Raymarine setup.

I have tried setting everything back to factory settings - still no show. Max wind is recording so the numbers are there somewhere I think


Any clues as to what can have happened? Since the direction is correct I am assuming the the is not fault in the connection. Am I right in this?

Thanks

might be a loose connection where the transducer wire connection to the head unit

Either the transducer has failed, there's a wiring fault, or the instrument display is faulty. You can start by checking if there's a speed output on the transducer cable by putting a voltmeter on the yellow and shield wires; you should get 0 to 5V, the windier it is, the higher the voltage.
 
Voltage measured

Thanks for the replies so far. Yes the anemometer is spinning rapidly!

Have opened the junction box in the saloon labelled "wind". There is a junction strip with 5 wires, black, blue,red, yellow and green. Yellow to black is -4.3 volts, yellow to red +3.5volts.

Sorry to be so ignorant.

Did you have the digital readout displaying VMG instead of Wind Speed?

Nope, VMG is zero. The max wind has been recorded as 27.2 which is since trying the factory reset 30 minutes ago.
So the numbers are entering the system but not being shown on any of the many displays that can show wind speed.

Thanks

Need to know a bit more.
Is the mast head unit directly connected to the head unit? (Model of Head Unit?)
Or does the Mast Head unit go via a Pod?
Do you have anything else that can display the Wind Speed?

Mast head unit goes to a junction box. Not sure I know what a pod is - sorry. The wind display is a ST60 Wind intrument

The wind can be siplayed all over the place. It can be displayed on one of two ST60 multi's and also the Chart plotter. I also have a PC that can receive NMEA including the wind All show the direction - with its variation. The ST60 wnd is recording the max speed since being reset.

Does this help???

I assume the Mast Head unit is connected to the back of this ST60 and not one of the others. If so I would be tempted to unplug the ST60 from the Seatalk Network. Connect Power to it and see if it can work independently.
If the Masthead unit is not connected to the back of this unit then I'm wondering if the unit needs to be set as a Slave and one of the others units is a master unit. A reset will have switched this back to the master unit.

Masthead Test:
masthead cable check with a volt meter, on these colors, using the shield or bare wire as a reference point, to the red 8vdc should be there, then to the yellow and green you should see about 2-6vdc, and then to the blue 0-5 vdc depending on how fast the wind is blowing,. 8vdc going up and the rest coming back down, if nothing is coming down then the masthead transducer or cable is bad, if current coming down then the display would be the problem.

According to this page on the Raymarine website, you're giving the wrong colour entirely for windspeed.
 
My ST60 used to show the correct direction but wind speed from "---" to "60" no matter how much it was blowing (it was really going crazy with numbers).
It turned out to be some bad connections at the mast base. So, some connection, somewhere could be the problem.

When you do get it sorted please let us know the outcome
 
Have you the instrument reading True or Apparent wind? I think mine doesn't give a True reading when stationary in the marina, but gives the correct value when on Apparent wind. True reads when the boat is moving and there is a boat speed input. David.
 
Mine is exactly the opposite. Shows speed but direction turns continuously like the second hand on a watch. Occasionaly it reverses direction and rotates anti clockwise for an hour or so.
