Hey gang, can someone please describe how the green oil pressure light is supposed to work? I think mine used to come on with the key in on position prior to starting but now doesn't do that every time. Then once started it will come on briefly for just a blink. Is something getting funky here? I heard that when the pressure switch fail the light will remain on. Will taking oil cap off while running be a good test to see if light comes on? I appreciate your help....thank you!

Yup, what Pancake said.

The pressure switch for the light is just a simple switch. When there is no pressure the sender is grounded and the light has a complete circuit and the light illuminates. When pressure increases it pushes against and lifts a spring loaded plate. That breaks the circuit and the light goes out.

If it's erratic in it's function (like you're describing) it's either the switch or the wiring. They do fail and new switches are cheap, so I would throw a new one in to troubleshoot. If the problem persists then you've got a wiring issue.
