SC Iowa | It is an open center system, 2 solenoids need to be energized to move the cylinder, the one going to the cylinder and what I call a blocking solenoid, it blocks the oil from returning to the tank so the pump will build pressure and move the function. Check to see which 2 solenoids get power going in and see if 2 get power going out. The blocking solenoid should get power when head is lifted, reel lift, auger swing or field tracker moves.
After thinking a minute, you could hit the reel lift and the unloader at the same time, this will energize the blocking valve with a different wire to see if that is the problem.
