Computer problem
1988 Jaguar XJS V12 Two Wheel Drive Automatic
My speedometer is not working. I replaced the transducer next to the transmission. I cleaned the printed circuit board and added two redundant grounds, one specifically for the speedometer and one for the entire board. After doing all of this, the speedometer still does not work. In fact, the oil pressure gauge is acting up; it is maxed out. The trip computer is no longer recording miles driven, but it still is recording gallons used. I am stumped. Help please. Do I buy a new printed circuit board or a new speedometer or a new instrument cluster? Or, do I go back and clean everything again? Thank you.
P.S. The tach is still working. The cruise control is not working but it did not work long before the speedometer stopped working.
