how to test oil pressure sender and gauge - The 1947 - Present Chevrolet & GMC Truck Message Board Network

OK, got my truck up and running with the new GM 350 HO crate motor, new 700R4 transmission, Vintage Air, new wiring harness, new gauges, etc. I am a happy dude!

Just got a few kinks to work out.

One is that my electric oil pressure gauge is not working. There is a new sending unit back near the distributor, wired to a tan wire. Gauge is pegged to the max pressure and never moves.

Is there something simple I can do to test that the sender is working, and that the gauge works, so I can find which is the problem?

Thanks - wiring/electrical is not my stong suit. Not sure what my strong suit is, but it surely isn't this!
