Combines R75 Auto header height control

Check your yellow plug on the head that plugs into the combine. Take it apart and you will notice how they connected the wires to the small pins. Sometimes these get loose. You may even have to solder them for a good connection. Normally I just spray mine with a good contact cleaner every week or so.

This is a somewhat familiar question on lots of cumputer run things these days. My first suggestion is to shut off machine, talk to them a bit, then suggest to turn on key and let things self test and fire up, then go ahead and start her up try again. lots of the times things will be back to normal and working perfectly. I think this gives things a chance to fire up with full battery instead of reduced currant from cranking. Good luck
