Hi guys,

I have built up a voltage switch kit, which I will use to switch on my thermo fan when the car is at a set temp. I am hoping to get my reading from the thermo sender unit for the gauges, but I am after a rough idea on the voltage at which they should turn on..

Just wondering if someone who has there car already warmed up can measure the voltage at the thermo sensor just after the fan has turned on?

Cheers guys,

Tim.
