so it was tested at the front with the multimeter on AC voltage and the reading went up with vehicle speed ? Tested at the sensor ? i would test at the sensor with the multimeter see if there is a signal , then the terminal on the speedo see if it is still there , if not renew the wiring between sensor and speedo .. it still may not work if the speedo is faulty . But you Have to have that signal on the speedo itself it's vital to know ..

yeah was tested at the front and the reading went up, should i retest the front speedo plug and then unplug and test the sensor and then rewire?
sorry im a bit slow!!

when you say terminal do you mean the plug with the three wires in?

Yes the 3 wire terminal block which plugs on the speedo .
Have the live feed and earth been checked out ok? Make sure the speed signal is still there with the plug plugged into the speedo too . But better to look at the signal with an oscilloscope . When you can see it in black and white you are happy its actualy there ...

got some progress today, took the car for a run and put some petrol in and the speedo moved to 15mph at speeds below 30mph and then to 20 over 30mph, so i decided to take it up the dual carriage way and couldnt get the needle over 20mph, the whole trip was around 3 miles however the odometer only registered 0.5 of a mile!!
