well guys hes talkin about a belt driven, the electric part on it is the clutch, and if you are running 12v constant through the pressure switch, if the tank leaks down the pressure switch will turn on the clutch, even if the engine isnt moving, ive had that problem a couple times, run the power to the pressure switch from a 12v switch source, like something that will turn on when the key is turned to accessory.
