level sensor.
 

Having my header tank made in ali and wondered if anyone knows of a dinky little level sensor that can be bought that screws into a boss. Not the big plastic things that you see on some of the header tanks or the ones that push into a large grommet.

Just wondered if the us passat was the same as ours or some badge engineered mongrel.

BINGO, Does anyone know how to turn what must be a resistance reading into a straight forward warning light?????????

A simple transister circuit with select support components would do the trick.

Need the range perameters of the sensor to work it out.

Its basicly an analogue to digital convertor circuit, i could probably knock up something but it would be a few weeks before i get a change with uni stuff etc.
