Boeing 737 Anti Skid Solenoid Valve Test Mag-Probe Test Light Does Not Lie
Below Matt Couture talks about his findings after using a Mag-Probe to make a Boeing 737 anti skid test.
It is my opinion after the findings with this test procedure, that the Magprobe is a more comprehensive way to test the valve.

As you will see in the second video, I had a meter hooked up to the “bad” valve.The resistance value moved around, but no more than the “good” valve below it. It stands to reason that testing with the Magprobe is more revealing; as it is a more direct representation of coil health because the normal operating current is being applied when testing with the Magprobe.

I theorize that if I were to use an analog meter, the “bad” valve resistance value would bounce around more than the “good” valve would when tapped. The digital meters use such little current that they will give false coil health readings(lie to you) at times.
The Video Below shows Two Anti-Skid Valve Tests demonstrated on a Boeing 737 1st Video Using a Mag-Probe / 2nd Video Using a Digital Meter.
