Probably something along the lines of "You don't have any idea what you're doing, do you? Seriously, stop poking at that like an idiot, you're going to set fire to something, and seeing as I'm just a figment of your imagination at this point given how long I've actually been dead, and I'm not going to help in any way if you do..."
I've never had my hands on that specific unit, but pretty sure there are several capacitors in them based on how large the heads are. Even the super small flash heads generally have at least the trigger capacitor in them, which while it isn't super large and powerful, it is still enough voltage to give you a bit of a stun. And when dealing with high voltage stuff it often isn't the shock itself that will harm you, but rather whatever you hit your head on as you stagger and trip.
But I am honestly rather curious as to how the setup for those units are, so it would be rather cool if you could possibly get a few photos of things while it is getting fixed.
