Volvo: 93 240 Wagon Oil Light, fuse one, oil light

Question
When my 93 240 wagon is turned off, the oil light on dash panel comes on and stays on. When the vehicle is started it goes off. I pulled each fuse one at a time and the light stays on. What else can I do, it must be being fed directly from the battery? How is this fixed?

Answer
Mike,
There must be a short in that circurt. Pull off the wire at the sender and see if there is power there. If there is trace the wire and find where it is getting power. I have not seen one but feel it is a good possibility that the cluster circuit card might be shorted. You need to trace and find the power supply.
