        ignition off , no oil pressure

        ignition on, oil pressure at 5

        start engine,oil pressure at 7

        rev up moves out of scale.

        cleaned contacts on instrument gauge.

        changed sender unit to new one.

        Visualy checked wires as much as possible.

        any one,to help solve the mystery ?

          mystery solved !

          a resistor has to be instaled,getting the 5 back to zero.

            Hi Gerben Haringsma ‍

            While I couldn’t solve your problem, I do recognise the solution – on my XJS 4.0 litre coupe there is a mysterious tiny bulb in the engine bay, that when removed makes the oil gauge at the top.

            Glad you solved it.

            Laurence

              mysterious car,the jaguar.

              the tiny lamp was your resistor ?

                the resistor should be 15 ohm.
