help needed - Temp gauge not working

[Johnny]

I have a gk76 which since I bought it the temp gauge has not worked.

I bought a new one to test and nothing still.

I then bought a new thermostat, temp sender and housing and nothing still.

On closer inspection I can see the wiring is a little messed up and suspect it has been wired incorrectly.

Does anyone know how it should be wired?

A Haynes would be very handy!!

Thanks

On mine it was a break in the wire between the temp sender and the gauge you can check by taking wire off of the sender and earthing it the frame you should see gauge go to max if ok . also might be worth checking earth lead onto thermostat block . hope this is some help

which wires should be connected to the back of the dial?

I have replaced the sender wire already.

2xblack/white 1xblack/green 1xorange 1xgrey should see letter markings on the back of the gauge next to connection pins
