So I finally had a chance to really play my new Dolphin Ring pachinko I got for Christmas. Something really strange is going on with it, though. The shooter only seems to work if I raise or otherwise stretch my other arm. It is the strangest thing. I can hold my right hand absolutely still on the shooter, and nothing happens until I raise my left arm.

Can anyone explain this phenomenon? The only things I could think of that could be a factor is currently the machine sits on a carpeted floor until I get a cabinet built. The other thing is I relocated the transformer closer to the shooter knob, since its old location was directly under the exit chute for losing balls. Could it be either of these, or something else entirely?
