Steady now Ryan ..... we are not there yet.
What we do know is that the actual Speedo motor works from the small connector on the board, and that the speedo board does convert the pulses to voltage to drive the motor.
What we still don't know is if the speed sensor works, and if so, are the pulses getting to the board.
It might be worth getting out your meter again, and identifying, on the larger 6 pin connector on the board, the two pins that come from the sensor via all the connectors. The two pins you want are the first two after the white plastic locating stud. The first is a Brown wire with the screen attached, and the other is the next one ... Yellow wire. I am assuming that the colours are the same as my jig, but as long as you get their positions right, all will be well. See pic below.
With your meter across those two pins you should get approx 1.6 to 2 Ohms. That will check the continuity of the loop. If this is OK, then assuming the sensor is working, then the speedo should work.
I will be posting the board back to you sometime this week.
.......... and if I can get the fuel gauge something like I'll know when to put fuel in instead of ' hang on,.....
Now ........ do you remember this which I posted to you on the 28th December:-
You may recall my PM, reference checking the Fuel Sensor out of the tank, well, having tested that, and the sensor back in place, it would be worth checking the resistance at the sensor with whatever fuel quantity you have in the tank .... it should be between the values I gave you. Now you can check if you have continuity from the computer plug, through the sensor and back, which should give you the same reading +/- an ohm or so.
Now here comes the difficult bit for me ..... I have to explain what two pins of the connector are the ones to do the check on.
Looking at the pin view, hold the connector in the portrait position, now orientate it to have the top two row of with 3 pins each, the next row below having two pins with a blank in the middle, finally you should have 3 pins in the bottom row.
The two going to the fuel sensor are, the middle pin of the top row, and the middle pin of the second row.
Did you get a chance to check this out yet ?
