Can You Discharge a Capacitor Using a Voltmeter?
We've received a lot of comments that many of you discharge run capacitors with a voltmeter. But can you (or should you) really discharge a capacitor with a voltmeter? Bryan tests this method on a turbo mini capacitor and compares it to the capacitor discharge tool he created. When we tested discharging with a voltmeter, we used the black lead on the common. It took a very long time to reduce the voltage. However, the capacitor discharge tool almost completely discharged the capacitor within 2 seconds. So, yes, you can discharge a capacitor with a voltmeter, but it will probably take a longer time than other methods.
