you are correct, dmroeder ... actually it IS the capacitor that needs shorting ...
but ...
my understanding is that if you short directly across the capacitor pins, then you take a chance that the resulting high current might be too much for the capacitor - and might (possibly) damage its dielectric film ...
I've heard that shorting the VBB and GND pins is safer - since it makes use of a "bleeder" resistor which limits the capacitor's discharge current to a safe level ...
or at least that's the way I've heard it explained ...
