Boeing 737 Anti Skid Solenoid Valve Test Using Mag-Probe
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 on this Boeing 737 Anti Skid Solenoid Valve Test.
As you will see in the video below 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. Matt Couture
