I inherited a Ford 2000 gasser from my grandpa, I think it's 72 if that helps, and I'm having oil pressure issues.
When I got it home, I changed the oil with 15W-40 since I figured its an old, worked tractor with an unknown amount of hours on it. The gauges don't work but the lights do I have no idea if the hour counter still turns. I thought it could use the thicker oil. I would get an intermittent "low oil pressure" light depending on what rpm the engine was turning. I thought it may be too thick for the old pump so I drained it and filled it with 10W-30 the manual calls for. Now the oil pressure light is constantly on, no matter what rpm the engine is running.
I am trying to find where the sending unit is so I can put a gauge in and get an actual number, hopefully telling me it's just the light being dumb. However, I cannot find where it is at all. I have a reprint of an old service manual that shows there should be a wire going to somewhere behind the generator and under (I think?) the oil filter but I cannot see where it's supposed to be.
Obviously, someone has been in here messing with the electrical before so I have little faith that anything is hooked up correctly. The light will turn off if I turn the headlights on. I think it is wired up with that red wire coming from the left. The service manual shows that it's a single wire that comes out of the loom just before the generator. I think it may be looped in on that wire nut that's on the exhaust manifold.
