My Saab accessory gauge denoting the oil pressure has decided to go wrong. When the ignition key is turned to the pre-crank position, the gauge flies up to the end of the gauge (hereafter referred to as the far end). After cranking (which causes the gauge to flicker slightly), the needle return to the far end of the gauge. The normal oil pressure light is still working correctly though. When I pull either wire (positive or negative) or both from the sender located just above the oil filter, the gauge remains unaffected with the needle firmly at the far end. Pulling the power wires from the back of the gauge or turning the car off returns the needle to the zero position. I'm thinking that the sender could be duff, but surely a more gradual death would have been seen. Is there a possibility that a relay, or fuse, might be at fault. I have no documentation for the gauge and would very much appreciate some help from anyone who has one of these gauges installed who can point me to a wiring diagram, or has also experienced this. Many thanks, Paul 1989 900 Turbo S http://saab.go.dyndns.org/
