Low coolant sensor/light testing (-95)
When i turn on the ignition the low coolant dont light up.. all the others light up and then goes out.. I first suspected a bad lamp in th housing.. but the lamp was ok when testing it at another location.
But when i jump the wires going in to the sensor the light on the dash lights up!
Questions:
1. isnt the Low coolant light suppose to light up at first when i turn on the ignition
2. is there some way to test the sensor located in the tank? Ohm?
Regards
Simon

Thanks, PM sent
Talked to another Corvette owner who has a -94, he claims that his light dont light up either when ignition is turned on..
how about your cars? Maybe its normal??

light
no test is normal. all the sensor is, is a blade of metal that is immersed in the coolant. when there's no coolant, the transistor that keeps the light off switches, and the light goes on.
ground the green wire, the light stays off. pull the wire off, the light stays on.
The ground to keep the light off is the coolant touching the engine water jacket, and the Engine block being grounded at the back of the cylinder head.

Thanks
Been in the garage know.
But on my car the wire is black and yellow/black
When i grounded the Y/B wire the light came on, and when i removed ground it went away.
Also tried to measure ohm thru the sensor, and it is no ohm, but will probably be if there where no water in the tank...
So it must be the opposite, that it lights when its grounded.
