late 80's G274. I cannot get the PTO to spin. I can feel it lock in/go into neutral with the side lever, but I don't believe the solenoid that diverts the hydraulic fluid to the clutch is working. The wiring all the way down to the solenoid seems fine. 12 volts, Key on, switch on. The Solenoid pulls 1.9 amps. Does anyone know if I should hear the solenoid click? If I remove the solenoid from the flow valve will it be pressurized other than the spring and residual fluid? Any other ideas on things to check? Maybe the solenoid makes no noise and is working buth there is no hydraulic pressure at the valve? is that possible? any thoughts or ideas are appreciated....
