I've checked the rotor, it is spinning. The sensor ohms out okay ( compared the fan sensor reading to the rotor sensor. I'm wondering if maybe a diode is bad in the control panel? This is my first combine so i wasn;t aware the head raises by itself. Makes it tough to hook up the grain head with it raising like that.
Heard that there was some kind of upgrade to help with the raising feeder housing.
Thanks for the replies, much appreciated
