Yes I have opened the EX up. It kind of looks like Cmdr. Data's brain. To make a short circuit in order to melt metal together is just PFM. As you know, if you run anything electrical, heat is your biggest enemy. It's best not to let entropy occur within the lean green machine and fry it's brains out. Don't even let it have the opportunity to do so. Otherwise Mr. Ohm will call up Mr. Murphy and Christmas is cancelled.

Anyways, have a good one.
