A continuity tester is a gadget that literally tests "continuity" or continuence, in other words, you use one to check where traces lead to on printed circuit boards. There are several guides on YouTube and Instructables, however they all seem to use 3v battery (as run an LED to show w...
When checking for continuity, you determine whether or not electricity can pass between two given points in an electric conductor. A continuity tester has two leads connected to a small battery, and when you touch the leads together to complete the circuit, the meter should register 0 resistance...
Use a continuity tester or a multimeter to check continuity of audio cords going in and out of the amplifier before attempting to open the unit up and look further. How Can I Identify an Amplifier Problem? Identifying the problem in an amplifier is easy: no power, no sound, or bad sound...
Restore power at the electrical service box. Carefully touch one probe of the continuity tester to a brass screw terminal and the other to a silver-colored terminal. The tester light will glow if power is coming to the receptacle. If the receptacle fails the test, check power across the hot...

DC to AC converters for cars are devices that allow a car to run on AC power. They are used to convert the DC power that is provided by the car’s battery into AC power that can be used to operate the car’s electrical components. How does a AC to DC converter work? Fig.1 A ...
To test alligator clips, all we need is a multimeter which has a continuity tester. Being that the only purpose of alligator clips is to electrically connect elements in a circuit, the only property that it has is it should be continuous from one clip all the way through to the end clip...
A continuity tester (found on mostmultimeters) will allow you to check if there is a break or short in the circuit. Continuity testers apply a voltage across a pair of test probes and measure the current in the circuit. If no current is detected (indicating a short circuit), the continuit...
