Good to be back, eh!!!
So last week I was home (an hour from where I go to school) and running my J-10 around to recharge the battery as I ran it down cranking on a clogged fuel filter. I replaced the filter, she cranked up wonderfully and I went off. I drove through the country for 20 mins around 45-60 mph and then headed to the highway to run up to 70. I pulled out of the intersection and easily gunned it up to 70. I looked at the gauged and the oil pressure was pegged above 80 and as I watched the temp slowly moved past normal and seconds later pegged as well. I shut down and coasted off the road. popped the hood, hardly any coolant out of the overflow and the radiator was not steaming over or anything as i could still touch it breeifly with no burn. I waited around for a few minutes and turned on the heat full blast cranked up and went. Gauges normal for 2 minutes then pegged. I went home 15 miles at two minute intervals, although I was pretty sure I had an electrical problem. Anyway, as a precaution I changed the thermostat and radiator cap. The truck ran fine the whole time. Never seemed too hot. Now the temp gauge runs a little colder, but the oil gauge fluctuates randomly and eventally just reads zero.
Any thoughts? I am thinking the oil pressure sensor wire is shorting or broken in the jacket. Anybody ever trace these wires?
