And if you don't have a screwdriver, the old standby of sticking your 
tongue across the terminals is often workable.

I have a mate who once claimed he could measure up to 50 volts with his 
tongue. His tongue was accurate to within about 1% but got a bit non-linear 
after about 35 volts. Mind you he was also the engineer who claimed...
         "There is no part of the human body that cannot be used in the 
pursuit of electronic engineering."

And I'll leave the rest to your imagination.

NOTE: Leave the bleed resistor on the cap for a while, they have a nasty 
habit of self charging. Something else Nige could tell you about at length.

Be absolutely Icebox.
