How big a capacitor should be discharged

Before you even start testing, make sure your capacitor is fully discharged. A charged capacitor can give off a potentially dangerous shock. You can discharge most capacitors by using a resistor across the terminals—but be careful. Some larger capacitors hold their charge longer and may require more time or specific tools to discharge completely.

How To Test a Capacitor

The voltage at first should read near the 9 volts (or whatever voltage) you fed it. Note that the voltage will discharge rapidly and head down to 0V because the capacitor is discharging its voltage through the multimeter. However, you should read the charged voltage value at first before it rapidly declines.
