I picked up this JackBot from an Italian shipping container buy, and the main thing I've noticed right off the bat is this big device wired into the main box output (the part that goes to the transformer). It looks like it splits off of a couple of lines into it, and then outputs power to the 12v, 5v and ground lines. This is most definitely not from the factory, so without having turned this thing on at all, can anyone hazard a guess as to why the previous operator might have felt it was necessary?
