Hi
Thanks for that. Really appreciated. So, are you saying that the earthing problem is on the circuit board itself, or in the 15 pin socket? i wasn't entirely sure by your message.
I have already checked the 8 pin connector on the back of the middle section and found the earth. I checked it had continuity with the sterring column so now im searching for other bad earths and think maybe its the circuit board itself.
The really weird thing is this has happened while/during I removed it (which is particulary soul destroying). Im wondering whether the earth connector point, which a screw goes through, on the circuit board itself which connects to the metal strip is poor or needs to be tightened.
Is one of those 15 pins an earth? Or perhaps more importantly, is it possible that one of them is being used erroniously as an earth?
The other weird thing is if i connect the screw hole connector on the board to an earth, then the gauges go mental. Why would they do that? Surely that would make everything cool, no?
thanks for your patiance and input.
MJ

Remove the gauge binnacle and take the time to ascertain the ground paths, at least one will have a screw or other fastener in it, use this to add a brown wire from the binnacle proper to a good ground point on the body .
Once you've done this and have the binnacle re installed, remove the tank sender using s 46MM socket of large pair of Water Pump Pliers, turn the key on , re connect the sender and invert it whilst you watch the dash gauge .
It should go from empty to full, kif not you'll likely have to carefully and gently take the fuel sender apart and clean it well using soft brushes like paint brushes ~ it's very easy to break the two delicate fuel sender wires , I am sure there's plenty of threads concerning sender cleaning ~ I've saved almost every one I took apart .
Keep us posted and try to remember : you're not a Mechanic so it may take you a bit more time and effort but you will get there .
I can dig your car being a "B.I.T.S.A", I used to build them, and Motos too, you're cleaning up some one else's lazy / sloppy job to don't let anyone rile you .
