Oil pressure gauge

[tico]

Thank you for adding me to your forum. I have a 49 Ford F1 Flathead six cylinder.The previous owner had replaced all of the gauges. The oil pressure gauge is not working. There is no power coming down to the sending unit. I took the wire off and grounded it and still nothing. I ran a test light on one side of the gauge and have power but nothing on the other side of the gauge. I am thinking maybe the gauge is no good. Looking for any ideas that you people might have. Thank you in advance

If grounding the sender wire does not move the gauge, I would first verify that the gauge has both power and a good ground. Since the gauges were replaced by the previous owner, it is also worth checking that the oil pressure gauge matches the sender type and is wired correctly. A faulty gauge is possible, but I would confirm the wiring before replacing it.
