It's a Navman. That's interesting what you mention about the transducer. Thank you all again!

Re: Testing Electronics

What kind of unit is it? I know that a Raymarine ST50 can be tested at the junction box to see if the signals are coming through. Basically, if the transducer is hooked up and getting power, it will be varying the voltage on the wires depending upon wind direction and speed.

Re: Testing Electronics

Hello!

The display does light up but it doesn't seem to be receiving any information from the indicator. I can clearly see what the display offers but the information is not correct. Furthermore, the wind direction needle stays in one direction and doesn't move. I believe that the speed is also inaccurate. I have tried to recalibrate and other things like this but to no avail.

What I want to try to figure out is if there is a way to test the wiring from the masthead cable junction box to the indicator at the top of the mast. Is there a way to test the electric circuit and the signal wire separately to see if they are functioning properly?

Thanks!

So I want to know if it's the display (or the wiring from the display to the mast) or if it is the indicator (or wiring from mast up to indicator) at the top of the mast.

If you can find the specs you might be able to find what signal is coming from the indicator.
Then disconnect the input and generate your own input somehow.

Most likely however the power is not getting to the panel.
I would think that even with the indicator not hooked up at all the panel should light up.

Re: Testing Electronics

Check all the connections, if it is totally blank either something is unplugged or the display is a dead ducky. I guess you could send someone up there blow on it....

If you get someone else to do that be sure to take pictures.

Re: Testing Electronics

I would think if the mast indicator was FUBAR you'd perhaps see some sort of life on the display, even if it was junk. If it's completely blank then I would suspect the display itself. Look for the obvious stuff first like has the unit got power etc.
