My John Deere 650J warning light came on because the oil pressure gauge showed zero pressure. This happened within the first few minutes of operation - the dozer hadn't been operated in the previous three weeks. I shut it down, checked the oil level, looked for leaks and any other abnormalities. I couldn't see anything wrong, so I started it back up. This time the oil gauge was pegged on maximum pressure at RPMs slightly above idle. I operated it for an hour at reduced RPM. While operating, the gauge indicated that the pressure came down a little, but was still way higher than usual. Has anyone seen an issue like this? Possibly a pressure sensor error??? The machine has 3,502 hours on it.
