Well folks, last night at work was the third time this has happened with our van, and this time I got to be the lucky driver. Yet again written up by airport security for not having our beacon on (Its one of those ones that is attached to the roof via magnet type thing, and with a cord that runs down and inside the door, and then to turn it on/off you simply plug it in or unplug it from the lighter). But here's the catch: it was plugged in, and it was working when I left the hangar. A bit of "jiggling" and on it went again. It appears we can plug it in all we want, but all it takes is a good bump (and trust me, between the kitchen and the terminal there is a lot of those) for the thing to loosen off just enough to turn the beacon off again.
Any tips on getting it to stay fully plugged in?
