Boeing Aircraft Solenoid Valves and Relays (1)

Hi Gents

Hope your are well,

I have used this Mag-Probe for few years now with a good result. If you have a fuel valve, lets say on a Boeing Aircraft B737 that will not open, you have to start by taking the connector off and measure the right pins in the plug to find out if you have power to the valve or not. And this process takes time. First you have to go to the WDM and find out what pins are used to drive the valve . All this takes time. With this little Mag-Probe you simply put the probe next to the soleniod of the valve on a Boeing Aircraft and if the light turns on then for sure you have voltage to the valve.
Turn off the switch for the fuel valve then the light of the probe will go off/on. So its the magnetic field that the Mag Probe detects. I had this problem with a fuel valve that was stuck, and it was easy to find out that the electrical side of the valve was working. Its not possible to say that the Mag-Probe will replace a Fluke Meter in any way, but the probe is a fast way to troubleshoot and limit out some failed components. When everything else fails you can start using the Fluke 🙂

The probe is a useful tool for checking to see  if a relay is working or not, by simply detecting the magnetic field with the Probe….

 This message basically talks about using the Mag-Probe to separate Mechanical from Electrical problems first and then if the light comes on and the relay is still not working you know you have a mechanical problem and one of the solenoid valves or relays needs to be replaced.  If the light does not come on when testing Boeing Aircraft solenoid valves or relays it’s time to use a Fluke Meter to make further tests.  It’s that simple and will save a lot of time.  Remember once you detect a magnetic field around  solenoid valves or relays you know you have voltage, current and continuity.  If you do not detect a magnetic field you instantly know you have an electrical problem with the solenoid valves or relays and more electrical tests will have to be made.

 This procedure works on B737, B757, and also a B767.  If the same valves or relays exist used on a B747 it should work on them as well.

About the Author
Bob Bartol has spent his whole life working with electronics in almost every capacity and spent many hours in Physics classes. He currently holds 4 U.S. patents and has been making a living off one of the patents "The Bartol Mag-Probe" for over twenty years. Bartol Research's Mag-Probe now has a global reach and is dramatically reducing trouble shooting downtime anywhere a solenoid valve. relay, or contactor is used. F111 Air Force Projects - European Flight Competition January 1968 Bob attended electronics school in the Air Force. Upon graduation he was assigned to a fighter wing in Germany. During his assignment he prepared seven aircraft for European competition. The fighter wings aircraft won the competition. Bob then returned to the United States and taught advanced radar for two years. Two years later, he returned to Europe. During this assignment, Air Force headquarters Europe selected Bob to open a Precision Measuring Equipment Laboratory (P.M.E.L) in England. It was the first of its kind in the Air Force. Upon his return to the United States, Air Force headquarters assigned Bob to Air Force research command in Florida. This was strictly a scientific assignment for research and development. After three years he moved from Eglin AFB in Florida to Edwards Air Force Base in California where he had direct contact with the National Bureau of Standards and supported research and development aircraft. During this assignment, he designed a modification for the TF X fighter (F-111). This modification made possible an additional 9800 flying hours per year. The F111 was the first swing wing aircraft in history. General Dynamics completed the modification prior to acceptance by the U.S. Air Force. Modification of F111 Aircraft General Dynamics March 1963 As a result of increasing this flying time Bob Received an award from Edwards Air Force Base for Increasing flying time of the F111 by 9,800 hours per year. The Award was Presented by Colonel Grumbles to TSGT Bob Bartol on June 17, 1963
