Near Intersection of I-35 & I-90 Southern Mn. | I have a Truesight 2 system on my Deere 9770 that is connected to Ag Leader's Steady Steer motor. Mine has worked very well for me both last year and this present year.
As you have indicated the row feeler sensors get supplied with 5V and ground and return a voltage to the system depending on the amount of deflection of the feelers. This means the range should be from somewhere around 0 Volts with a full deflection one way and close to 5V the other way. With the feelers near the center, the reading should be in the middle at close to 2.5V.
When the system detects a deviation from the "center" voltage, it creates a corrective action to turn the steering motor in my case or the hydraulic steering valve in your case.
My first thought was that the sensor is a potentiometer much like the height sensors that are used in various places on my corn and soybean heads. I believe that is incorrect and that the sensors are "rotary encoders" which inform the system how far the sensor has been rotated and in which direction.
I have played with them somewhat on the bench with some experiments with my microcontroller hobby but really don't have a good understanding of them. What I am leading to is that the problem of "testing" your sensors may not be as simple as my original thinking. Your Truesight "box" may have some problems of its own.
I did perform an update on mine preseason. I have no idea if you have done one or if that would be of any improvement. The update is possible to do via their app on a smartphone that does an "over the air" update from the smartphone to the microcontroller inside the Truesight controller. Possibly yours is the original Truesight so maybe this doesn't apply to your situation.
When I first got my Truesight 2 Winter before last, I did call and talk with their Tech people. They were excellent and I would try to contact them if I were in your situation. You are correct in that the ownership has changed so the support may have changed but I would try the number the other poster has suggested.
Please reply with the solution when you find it, since a similar situation could haunt me some day.
