listen to this, my warning light for coolant level only comes on when i have too much coolant and turns of when
i dont have enough, puzzeled!

 

Sounds like it has ended up being fitted upside down!!

It works on a proximity switch and an actuating magnet in a float so that when the float drops, it puts the light on..

 

Clever things these series ones eh

can all the sensors for the yellow lights on the dash still be bought from ford? Daz? lol

 

Don't think so to be honest Dave but I think I may have seen a possible substitute for the washer and header tank sensors.

I have also found the pad sensor warning wire plugs that usually break off.

The electronic dipstick is no longer available.

Fuel light is on the tank sender unit for the guage...

 

so when either these sensors are kapoot the lights stay on on the dash, i know they flash when u start it up, why? electronic dip stick? i think i may have one kickin about !!!!!!! i thot it was off some volvo or summit pmsl pad wear indicators, i think i got 2 plugs sittin bout my inner wings for these!!
Pretty advanced for its day eh?

 

These sensors are available from many different Ford, not just S1s. So they cannot be considered rare. The round 3-pin connectrs are still available from large electronics suppliers like Farnell.
Lights flashing on startup means that there is fault in the circuit.

 

aah cool thanks jesse.
