    • Inspect your capacitor and note the following:

    • The voltage rating of either your capacitor or the device

    • Where the terminals are located

    • Attach two wires to an incandescent lightbulb—making sure the bulb's voltage rating is greater or equal to the capacitor's.

    • Don't touch the two wire leads together during this step, as this could short circuit the capacitor.

    • Lay one wire lead on the head of the terminal.

    • While holding the lead in place, lay the other wire lead on the opposite terminal to complete the circuit.

    • Hold this position for a few seconds or until the lightbulb completely darkens.

  4. How to Discharge a Capacitor in Large Machinery, Check with a multimeter: 步骤 3 中的图像 1，1

    • If you have a multimeter, you can check to see if the capacitor is fully drained.

    • Set the meter to its DC voltage measuring mode and measure across the terminals.

    • Any value under 10 volts means your capacitor is sufficiently drained.
