Is Is the wire tied to the railing? I think not, What I can do to the wire tied to the railing ?
Haha, I almost made the same mistake so I looked it up on youtube and some dude has a visual walkthrough of the entire game. I didn't actually see him "tie it to the fence" but I did notice that in his video, the sparking wire was connected to the fence.
Sadly, for our poor robot friend, it took me several tries before I realized I needed to disconnect the juice going to the wire BEFORE attempting to tie it haha.
