I have been reading previous posts regarding glow plugs and the glow plug dash light. I have read that the glow plug system has a separate temperature sensor (attached to the green wire) and I have read that the No. 1 glow plug controls the temperature sensor function. Can anyone clear this up for me?

If there is a seperate temperature sensor, is it about the middle of the engine block (attached to the green wire?)

My glow plug light on the dash will not come on, however, I believe the glow plugs are working. I live in Indiana, and I have yet to have a problem starting the car.

I have also read, however, the the glow plug relay makes a ticking noise when working and mine is always silent. I have not replaced the glow plugs, but they look nearly new. The dashboard glo plug light will light if the circuit is bypassed, so I know that it does work.

HELP! Any advice is appreciated.

Thanks.
