Wiring harnesses are crucial to aircraft as well as anything that requires electrical power. Often InterConnect has customers approach us because they have a project that is behind schedule, there’s an inoperable aircraft on ground, or a crucial modification needing to take place in the field before the aircraft can be mission ready.
Our customers sometimes want us to move fast like the roadrunner. Beep! Beep! This brings us to the question at hand, “What does it mean to ‘beep out’ a wiring harness?” To “beep out” a wire harness means to perform a simple continuity check. It is called “beep out” because when there is continuity, the basic audible continuity device, makes a noise. This noise sounds like the roadrunner’s “beep”.
To see an article posted in 2014 about an aircraft that had to have 10,000 wires beeped out, touch here. What a time-consuming thing to “Beep Out” a wiring harness! Thank goodness for our DITMCO machines. At InterConnect Wiring we go well beyond “beeping out” every wiring harness that we manufacture. Anything from F-22, F-16, F-15, EC-130, B-1B, etc. we go the distance; much farther than the roadrunner!
Final thoughts… in manufacturing flight-worthy wiring harnesses, cables, and panels, a simple “beep out” test is not adequate. A fully automated test is of utmost necessity. Refer to this article about qualitative tests to check the integrity of an aircraft’s Electrical Wiring InterConnect System (EWIS).
