Strange TackTick problem

[Gixer]

My MN30 displays have stopped showing information and just show dashes. The system was working fine and just suddenly stopped.
What I find odd is that I still have wind data to the T122 thought the quark to the iPad. I’m guessing it must be my hull transmitter but before I start buying stuff does anyone have any ideas?

I have had this a couple of times over the 10 years or so that I have had TackTick instruments, affecting the speed and depth displays (I have two). In each case it was the connector for the power supply to the hull transmitter, which seemed to have very little 'grip'. I ended up by putting some sticky tape across it to make sure it stays in place. However, I'm not sure how this relates to your wind instrument, since this has information sent direct to the display from the masthead. Hope this helps a bit

Thanks for the response.
The power to the hull transmitter looks fine, I’ve taken it apart and reconnected and nothings changed.
I’m not sure how they are interfaced, I’ll have to read up. As you say, I thought the wind was completely separate also which doesn’t make sense for it to have the dashes.

Have you the nmea gateway installed? We have this intermittently and find that this also picks up the data stream from the wind head and it’s a week signal that seems to stop the cockpit display showing, the gateway is inside the boat and in better line of signal

There's a lot to be said for simple, hard-wired systems.

Thanks Daverw
Yes, I have the T122 NMEA interface. Does the masthead unit talk directly with this interface? I always thought it went though the display.
Just had a though, I haven’t moved the boat since this has been happening, could it be interference from something?

I moved the gateway to forward of the mast in the forward cabin roof, I found that the mast being between the mast head and the display reduced signal strength sometimes. Apparently the gateway acts as a repeater, it was raymarine tech that told me this when I was having issues a freeway years ago. They do refer to this in the manuals of the mast rotation sensor. I confirmed this when I sent the display away to them to be checked and found that the autopilot still had wind data on it as well as the chart plotter over the 2K network. You still need the display to calibrate etc however.

Hi, I hope that someone has seen this before. I have a Raymarine Tacktick system on my Corby 33, it came with the boat, which was new to me just under a year ago. I have had difficulty getting the speed to work. When I launched the boat there was no comms with the speed, and depth from the Triducer. just dashes. I replaced the hull transmitter with an unknown spare that came with the boat, this produced comms, but no speed, 0.00 knots, the depth worked. I then replaced the triducer with a new one and speed gave a reading, however this is sometimes sensible, and works for a few mins at a time, then it reads low for a few mins, the reading is around 60% of what it should be. I have replaced the hull transmitter with a new one and it is the same.. i just can't rely on the speed reading, meaning true wind is also screwed.
Does anyone have any ideas? could something else be interfering with it or dragging a signal down?
I am wondering if i have a duff new speed transducer?
Help appreciated

Have you checked signal strength from the hull depth sender transmitter, I’ve now changed system but my old Tacktick suffer From weak signal to the head unit, I moved it closer and problem went away

If you're getting 0.00 for speed it means that there is a connection established between the hull transmitter and the display head but the hull transmitter is not getting a signal from the paddle wheel. Take the speed transducer out and spin the paddlewheel and see if you get any reading above 0.00. If not your speed transducer may have a bad connection or has failed.

If you get low speeds it could mean that the transducer is failing, has a poor connection or the paddlewheel is being prevented from rotating properly by some dirt or growth.
