Hey guys I've got a issue with my oil pressure gauge on my: 1992 YJ, 2.5l, 5 speed manual with the gauge type sending unit.
When i turn the key to the ON position the needle goes from the far left of the gauge and comes up to the 0 line. but when i start the engine the needle does not move, it stays in the same spot all the time.
I have checked the oil pressure with a manual gauge and it is 60psi cold and about 30psi warm at idle. I have also replaced the sending unit and took the gauge cluster out to inspect the back of the gauge. Nothing looks out of the ordinary as far as i can see.
I checked the connector that goes to the sending unit with a test light and it is getting power but makes the light very dim (not a full 12v is going to it) i am not sure if it is supposed to be that way or not.
I don't know what else to do, if anyone has any ideas or has had the same problem please chime in.
