I'm having trouble with one of my height sensors not working on my Case Ih 4430. It will show a height but it appears to be off and it won't engage. I can get the other side to work and I've concluded it's not the sensor as I've swapped the sensors around and they work on the other side. Eventually I found that I had a couple wires partly broken by a boom joint. Now i soldered them but it still doesn't work. I'm wondering if this would be an area that would be sensitive to extra resistance and that would be why? If so how can I repair it without changing the resistance in the wiring or am I stuck with getting a whole new harness?
