Combines Problem with cornhead header control

Are you saying the header will not move at all or are your header and tracker mode switches both set to an auto functionIJ Auto header modes include, return to cut, float, and header height control. If so then the seperator and feeder must me on. The reel mode switch merely shuts off the reel drive valve in the corn position. Place the switch in the rear most position for manual control and then using the ratio control knob next to the switch you can control both the speed of the reel drive and bubble up auger if it is plumbes like it sounds.

Well, what happens is, if I am in rear position of switch which is for corn, the automatic header control works fine like it should but there is no oil going to reel and bubble up auger. If I move it to manual or automatic the automatic header control bottoms out the head but the reel and bubble up work. The separator and feeder have to be engaged for automatic header control to work.

I'd have to go dig a schematic out, but sounds like there is a short between the header mode switch and the down switch for the header. When the header bottoms out is there a down arrow in the header height display windowIJ
