This is over my head but had a similar issue the first day with 701. There is a box that has the hydraulic fluid go through it mounted on the drivers side rear center of the engine . It has 2 solenoids. One of mine was frozen and didn't move and had to be replaced. Newell said when they add ground the solenoid closes restricting fluid and turning off or slowing fan.. If it gets no power the fan runs continually.. Hope that helps.
