i have a 2018 JD 544k with 777 hr the problem i am having is the cooling fan is not working properly, the fan is running at 200rpm at 100% command, and about 500 rpm at wide open throttle, I tested for power at solenoid I have 26v when running, and tested solenoid, this machine does not have reversible fan valve, the hydraulic fluid is at the correct level any advice would be appreciated.
