The short of it is in the Title. All gauges did worked, truck has been parked for over a year. Started up and everything still worked. Moved the truck around a few time, still worked. 1 day, turn on and no gauges worked; Power yes, all lights work, signal etc and no digital. Also, I resoldered all the main pins thinking "it could be but with No sign of damage on the board. My theory is a corroded ground in the engine bay. What'chu think??
