Help needed with a Thermo fan

RX MIDGET · 02-02-2011, 04:23 AM

Hi,
After connecting an Autometer Water Temp gauge, my Davis Craig fan does not come on at all!

(Note: Tested up to 110 degrees C without it coming on - however I thought that the gauge reached the 110 degrees C alot quicker than I am used to - just 4 minutes).

The fan is wired through the supplied Autometer sender in the radiator - the gauge appears to work no dramas!

I have had a good look on the fan, but can not find an adjustment switch. Why would it need adjustment - as it worked well with the crappy old gauge???

Could the problem be the last gauge was degrees F and the new one is degrees C?

Note: I am replacing the old gauge as it was "mis-matched" with the old sender - normal driving (after 10 minutes warm up) it sat on 230 degrees F with the thermo fan coming on at 240 degrees F, ever since I have owned the car.

I am lost, any suggestions? HELP!
