Vic, I was having trouble with my internet provider yesterday most of the day and did not see your post until this morning. Hopefully, you have found the problem by now. Anyhow, the oil pressure switch is on the top front of the engine. I think it's just above the water pump. The coolant temperature switch is on the left hand side above the alternator. I think if you look at the front of the engine you will see the oil pressure switch pigtail electrical wire that looks similar to the coolant temperature probe.
The oil pressure switch opens when the engine oil pressure is above 6 psi. With the engine off, you should be able to read zero ohms between the probe and ground because the switch is closed.
Are you sure you don't have dirty battery terminals also? Your problem sounds like the battery might be making intermittent contact and causing fuse #2 to blow...just a guess. Do the headlights work? If the lights don't work and the tractor won't attempt to start, then you could have dirty terminals or the main 40 amp fuse could be blown. If you have good electrical power and the engine won't turn over, then you need to check the safety circuit. If the engine turns over and won't start, then you have to look for a problem with the fuel solenoid circuit. Fuse #2 is part of that circuit.
Good luck. Nothing is more frustrating than a tractor that won't start.
