Navman wind 100 transducer wiring

[chewi]

My Navman wind100 started misbehaving, and I found that most of the wires in the transducer have broken from the connector. I could solder them back on, but don't know which pins are which.

Does anybody out there know the colour sequence of wires to the 5 pin connector inside the transducer.
(The wires are not the same colours as the cable from there to the instrument, so I cant colour match)

I have tried their repair shop in wareham but they are no help.

if anyone has a transducer to sell or lend I'd be interested.

Are the wires in the thin "tube" broken, or are they broken in the part that is fixed to the masthead?

In the last case: the connector on the other end , near the display has the same order of wires.

its the ones in the thin tube, not the mast wire

I've tried to get the connector out a bit, the wires are indeed extremely short. But as far as I can see: numbered left to right seen from the outside, starting from the notch:
1:black
2:red
3:blue
4:yellow
5:white

In the worst case, I have a spare (working when I took it off).

You absolute star!!
I will try that tonight, and failing that if you can part with your spare I'd appreciate it for a price.

Its still unpredictable even with those wires fixed, so it might all have to be retired.
Do you have a spare display head as well?

Apart from the mast head unit, I have the bulkhead display with a molded-on connector, and an NMEA tail. However, the cable inbetween is sort of hard-wired into the boat, and damaged as well. The systems were fully working when I dismantled them a few years ago, and have been stored dry. I bought a Tacktick system, app. same size display but much bigger windrose.
I'll PM you

I found that within the sensor red/black go to the speed and then to the direction PCB's to provide power, blue feeds speed back to the instrument, while white & yellow do the direction.
The direction vane spins a circular magnet that passes close to two transistors positioned at 90 degrees to each other.
The speed vane has two small magnets that pass over a single transistor, they either act either as a motor (Unlikely, inaccurate) or a pulse generator (more likely)

The colours then change at the masthead socket. Oddly the white in the sensor does not connect to white in the cable, it goes to the brown, while the yellow in the sensor co

sensor... mast cable
black > screen (0V)
red > red (power, but not direct from boat supply)
blue > green (speed)
white > brown (direction)
yellow > white (direction)

It would have been helpful if they said that in the manual..
