    Oil pressure gauge faulty reading

    The oil pressure gauge on my 91 SC is reading too low. I have tested it by shorting the wire from the sender but is moves just shy of L and barely within the marking for normal. Oil pÄressure sender is new and oil pressure is checked with mechanical gauge and it's ok.I have the cluster out but don't know how to check the gauge. Any thoughts on how to test it?

    Thanks for the input but problem solved. It was the circutboard to the right of the cluster that was not entirely in place and the wire from the oil pressure sending unit that was faulty. Replaced it with a new wire and everyting works fine.

    Update

    Someone had replaced the instrument cluster with a cluster having the 20 ohm resistor on back thr oil pressure gauge. Turned out the sending wire also had the resistor in it so I bypassed the resistor on back of the cluster, as it was easier, and now it works as supposed to.
