The terminals of the cap look worse than the screwdriver does. Frankly it doesn't look too bad, just a dark deformed spot no larger than 2mm across.
The worst I've seen from shorting a cap was one time when I was attempting to fix a computer power supply. It was making a buzzing sort of noise that was identical to that of a wire just barely brushing against the fan as it spun. I had had this problem before so I did what I had done before. I knelt down to the computer and poked a screwdriver through the fan grill, while it was still plugged in (yes, yes, stupidest idea ever). Needless to say I accidentally poked the main capacitor bank and since the middle of the screwdriver was touching the metal casing the bank was shorted to ground. All I remember was a loud POOF and sparks shooting at my face. I leapt back in utter terror, ripping the now-welded screwdriver out of the case with so much force when I let go of it, it flew almost 10 feet.
It was my first capacitor shorting experience.
..... if are all in series, it's 650/6=108 farad total, if they are 2 paralleled series of 3 ones (seeing how they are posed in the holder, it seem the more probable combination), they are (650*2)/3=443.3 farad, and if they are 3 paralleled series of 2 ones, they are (650*3)/2=975 farad ..... doing series/parallel combinations is an usual way for manage the very low voltages of those capacitors, but there's no way for interconnect 6 elements all together and still get the same capacity of a single one, must be 4 or 9, for do that .....
