Check your voltages for left right and center header height. My guess is left side is too high. Go to DIA, EO1, then addresses 22,24,26. Left center and right. When head is raised you don't want any more than 4.5 volts. Lowered you want less than 2.5. This is changed by lengthening or shortening the turnbuckle rod connected to the potentiometer.
