Sierra cossie washer fluid low sensor.
does anyone know how these work. Mine has stopped working properly. The warning light flashes a few times the goes off.
I've got an earth and 5volts. Is this right. I've had a look at the sensor and can't see how it works. There is a bit of metal on the flap part of the sensor. Does this rise up and something inside the sensor reckonise it?
I just wanna confirm its the sensor.
Thanks.

Yes I've got 5 volts when it's unplugged. I've ordered a new old stock switch to try. The wire from the warning module in the dash to the sensor is OK too.
If it doesn't cure it I will just take the bulb out ha ha. I just like things to work.

Yep it's handy little warning light to have defo get it working if you can. I had a pipe split on my coolant circuit on my 3dr and level light came on to warn me before temps had even started to rise. They should have all had em imo.

If the sensor is disconnected the light will flash a few times and then go off. If you have checked that you have 5V and ground at the plug at the loom that is good. You can also measure the electrical resistance of the sensor. In both high and low states it should not give infinity.

Yes the light is flashing a few times then it goes off. I hope its a faulty sensor.

Is there another metal contact on opposite side of the one on the float? Is the float mounted horizontally? If so Id clean those contacts up and see if it cures it, if its only supposed to be 5V then itll struggle on a bad surface like that.

Metal part is most probably a magnet, and the switch is inside the black part to keep it away from water.

I would have bet on 12 volts though

The metal part is definitely not a magnet. The only thing I can think of is the wires inside the switch sense the metal when the float is touching the black part of the switch.
The new switch has been posted so when it comes we will see what the cracks is.

Thanks for the info, I did'nt know there was one. In the 25 years I have had my Saff the windscreen washer bottle getting low has never happened so I guess the light has never come on!!!

Ford were strange like this, its like the MK1 Ghia had wooden door cappings and footwell lights. 2WD never had the latter, yet they reappeared on the 4x4.
I have always believed the reason to be cost cutting.

My new washer fluid low sensor came today...
The light still flashes ha ha. I'm gonna check to see if there is a 12volt libw coming out of the bulb failure module to the switch.

yes I checked this out the other day. There is about 4 wires with the same colour. So could it have 5 volt feed or should it be 12? This is the next thing I was gonna check,to see what the voltage out of pin 20 at the module.

as you can see in the pic the switch is open so it has a bit of resistance
the switch is closed and the resistance isn't as much.
I checked my old switch and there was no resistance at all. It was an open circuit. So im chuffed its fixed.
