Let's simplify this.
If you have a 100' spool of 22/2 awg control wires, the resistance is sufficiently large that you can use a common DC resistance meter to know if the two wire are jumpered at the end or there's a short somewhere in between, because the wire resistance is large enough to provide accurate reading that makes the contact resistance at connections negligible.
If the 100' spool was 4/2, the per/foot resistance is too low to resolve length with a common meter and connection resistance would add excessive error.
Lacking specialized equipment, you could push a few amps with a power supply through a resistor while measuring the current. For example, if you hook up 2 ohm resistor and push 5 amps with a 10v power supply and you see a 11mV drop across the winding, you know that you've got 0.011/5 = 2.2mohms.
R = V/I
To read change in number of turns due to a short, you'll have to read the inductance. Measure the inductance on all 3 windings. There should be no continuity between coils and reactance should be the same between the three.
