Thanks mininuts..
I should get a good look at it tomorrow and am now armed with an aray of experiments to do....
Hopefully I'll get to the bottom of it.

Just short the gauge side of the sender plug with a bit of wire to a nice clean earth and see if the gauge goes full scale.

okay, what does this tell me.. I shorted to + end of the connector with the earth on the body work and all that happened was sparks flew and I burnt my finger! do I need thicker wire? The engine was not running but the ignition was on and my wife said that the gauge had not moved.

When I used the same bit of wire going to the actual earth point (under the coil) I still got sparks.

you have a late water system, thats what it tells me......

you need to join the two pins of the temp sender plug to see the gaugemove, if it isnt a wire prob

thanks for the reply, I have already tried all of these ordinary tests.

I get 12volts at the sender units socket but no gauge movement, I have also tried and tested two seperate gauges with no joy... although maybe I will have one final test of the spare gauge across the pins at the sender units socket.
