Serena Il, Center of the Universe | Ok new to me 930 on a new to me 9750. The head originally had DAM which I replaced with the Active Header Control. Replaced the right hand Dam sensor with a potentiometer and a new wiring harness. I can calibrate the head as per the instructions in the book for the header height resume. When I turn on the header height sensing option it quits working on the down side. When I push button 1 the head raises to is set point. When you push button 2 the head drops a couple of inches and stops. if you keep pushing it it will keep dropping an inch at a time. If you shut the sensing switch off button 2 works fine.
Any ideas guys. I cleaned the potentiometer area and it is free of debris. I inspected the connection at the head and it appears ok. |
