If it's not been updated I think the original control on these didn't have the cable, but had a solid rod that went from the pads direct to the potentiometer. All the rods across the back were connected to the one rod that actuated the potentiometer so the first pad that felt ground pressure would actuate. Your potentimeter could indeed be turned around backwards as he said, but unless you've just replaced it I doubt anyone else successfully used it that way. Could also be that the height and sensitivity are both at max and as soon as it senses the ground it automatically drives it up all the way. Start with your sensitivity knob turned fully counter-clockwise and your height just short of that. You should be able to hold the switch down, let it hit the ground, and let off and only come up a minimal amount. Make sure your auto-height switch is on. If it still comes up, try the same with the sensitivity and height adjusted the extreme other way. Could be they are wired backwards but also not real likely. My reel speed rocker switch was wired backwards when I got my last combine, about drove me nuts. If either of these adjustments don't make a change, I'd be suspect of either the potentiometer being backwards or being bad.
