Had another look, I have;
1 purple wire (connected to the 12v terminal of the dial)
1 pink wire (connected to sender terminal of the dial)
1 pink & black wire (connected to the ground terminal of the dial)
The gauge does not flicker or move when the ignition is turned on.
I've tried bridging the earth & 12v to another (working) dial which made no difference, also switched the pink wire with the pink/black wire... still nothing!
I do wonder if it is just that the fuel tank is empty, but all the other gauges flick up to zero when you turn the ignition on.
Any further thoughts?
Thanks again for the help so far!
