Before using a capacitor tester to test a start capacitor, what is the first step that should be taken?

• A. Charge the capacitor
• B. Discharge the capacitor
• C. Place a screwdriver across the terminals of the capacitor
• D. Make sure the capacitor is connected to the motor

Answer: (B)

Discharging the capacitor is the first step that should be taken before using a capacitor tester to test a start capacitor. This is critical because capacitors can hold a charge even when power to the circuit is off, posing a serious shock hazard. By discharging the capacitor, you ensure that it is safe to handle and test. Discharging involves connecting a resistor or a discharging tool across the terminals to safely release the stored electrical energy. This process prevents accidental shock or damage to the testing equipment that could occur if the capacitor still holds a charge. Proper practices in safety and handling ensure that the testing can be performed accurately and without risk to the technician. Therefore, making it a priority to discharge the capacitor is essential in any electrical work involving capacitors.
