A continuity tester (shown on the left) helps verify if an electrical component is receiving power, though it does not measure current. See additional images of hand tools for reference.The device features a battery encased in a housing, with a test probe attached to one side and a test wire with an alligator clip on the other. It is typically used with the power off to check if an electrical component is powered and to identify the source of any issues.
To operate a continuity tester, first unplug the appliance and take it apart to access the component you wish to test. Attach the clip to one connection of the component, and touch the probe to the other. If the component is properly powered and transmitting electricity, the tester will light up or buzz, indicating the circuit is continuous. If the tester remains off or reacts faintly, the component may be defective.
Warning: Always ensure the appliance is unplugged or the power is switched off before using a continuity tester.
