My 9660STS started acting up on me a bit...When I turn the field/road lights on at night the cornerpost backlighting is supposed to come on so you can read the harvest monitor, machine settings, speed, etc. For some reason this year it is working backwards. The backlighting is on when the field lights are off and the backlighting turns off when the field/road lights turn on. Has anyone ever seen this before? It makes it a bear to make setting changes at night. Thank you!
