I'll second that! Did the same thing a month or so back. Truck was
cruising just fine, when I checked the guages and no indications on any
of them. Immediately pulled off the road, where I discovered the master
switch was in the OFF position. The truck even idled smooth. I turned
the switch on and WAH-LAH I had oil pressure, temp., etc.
Be careful out there
