Oil Pressure Gauge

[Nike]

Trying to get my O/P gauge working. I have mixed some different years when assembling the dash and wiring, and I think I have an 83 speedometer and gauge assembly/printed circut etc. and maybe a later underhood wiring harness because it has a connection for a second oil pressure sender. Anyway when I turn the on the key electric gauge pegs to the highest reading. Anyone have this problem or a hot tip. Thanks Nike

That means that your oil pressure wire is grounded out somewhere.
Thinking about coming out to the Fall Crawl ?

Are you using the large, bell shaped oil pressure sender?

Yes I am using the large bell shaped sender, I tried the later model smaller one and got the same result. Also yes I am going to make the fall crawl on Saturday only. I would like to make the stock gauge work if possible, but if it doesn't happen I will hook some plastic tubing up with a plain pressure gauge. Any ideas are greatly appreciated. Thanks, Nike

What happens when you disconnect the wire from the sender?

It does sound as if the wire to the gauge is grounding out somewhere. No connection to the sender (ground) the gauge should sit at 0. If you ground the sender wire to the block, it should peg out at max.
