Among some of the most important tools for home improvements is the continuity tester. This tool can determine electrical current or continuity. Wall outlets especially can be tested with this device which is also called a multimeter or multi tester. Read on to learn more. more »

When performing electrical repairs or troubleshooting problems with electricity, there are some basic tools that are needed. A voltmeter and a continuity tester are critical to help find problems. You can purchase a combination voltmeter, ammeter, resistance meter and continuity meter at a very low cost. A separate continuity tester is cheaper than a multi-meter; here's how to buy the right one. more »

One bad solder joint can compromise an entire circuit. Some bad solder joints are obvious. The component is pulled out of the circuit trace, or the solder is cracked and corroded. At other times, the bad solder joint is not so apparent. It may look fine to a casual inspection and still be a bad connection. If that happens, the only way to check continuity is with a multimeter or continuity tester. more »

Check to ensure the circuit breaker hasn't tripped. If it hasn't, turn off the power to the circuit and go back to the switch and remove it from the box. Using a continuity tester, disconnect the switch from the wires and touch one tester probe to one switch screw and the other probe to the other screw. The tester should turn on when the switch is "On" and turn off when the switch is "Off." If not, the switch is bad. more »
