Sir Pharaon . . . . .
Since I still do not know product brand nor specific model, I will just engage in concept of design.
With both of these sensor input connections being black, I then can possibly assume that this uses the simplest methods of detection of rotation of the actuator.
We had the potential options of an optical light beam disruption of detector type or a Hall effect device responding to the rotation of a close proximity magnet or, in this case, I believe it will be using a rotating magnet in the close proximity of a magnetic reed switch.
This spinning magnet is mechanically inserted, somewhere in the gear down process of a very fast spinning DC motor, on down to the VERY snail paced incremental creeping of a linear actuator shaft that either pushes or pulls a receiver dish across its orbital receiving arc.
Those sequential pulses / shorts across the line, are used to keep up with where the dish is pointing in it's moving through the orbital arc, by the use of upwards of 1000 received points of reference / pulses to finely differentiate pulse count to dish position to satellite to be received.
I think that you are not receiving that pulsed info updating now.
Test 1. . . . .
No power to unit .
Disconnect the two sensor wires from the main unit and use Ohm metering in its low range to see if there is an open or a short being across the line .
If , by chance, a short reading is present , take one wire loose at the actuator connection at the dish to see if the short disappears.
If so, interconnecting wiring is being good .
If experiencing the greatest odds of not finding the satellite dish position, so it was not initially showing a short condition across the sensor wires, then test this way.
Have the sensor wires loose at the main unit and connect your low scale adjusted ohmmeter across the cleaned bare wires.
Power up the main unit and press either the east or west switches just long enough to see if you are getting a reed on off switching action to the ohmmeter from the reed switch . Usually it's about 1--------5 pulses per second.
I wait for your test response answers now.
