[FSPA] strange shock from unplugged pinball

[Dan Reynolds]

i believe you can discharge the coils while the game is on, by opening the
coin door (to disable the high voltage circuit) and then flipping the
flippers once or twice to drain the capacitors.  i'm pretty sure i've done
this on either WOZ or STTNG.
