There are some simple electronic tools for automobiles that provide quicker results than more advanced tools.Auto test lightsare such a simple but useful tool. Also known as a circuit tester or test lamp, it can check the presence or absence of electricity in a circuit. Easy to use, this t...
Testing voltage follows a simple process. For those of you new to electrical testing, we asked our resident Pro how they might teach an apprentice how to use a multimeter or voltmeter. Once you know how to use a multimeter, you can move on totroubleshooting and fixing electrical problems, v...
Resetting a circuit breaker is a simple process, as long as you follow some basic safety guidelines. Andy Cross/Getty Images Most homes use circuit breakers that turn off power to a room whenever an electric overload or short circuit occurs. For the uninitiated, the circuit breaker convenientl...
Before cutting into the wall or ceiling, turn off the power to the circuit where you’ll be working. Use a circuit tester to double-check that the power is indeed off before proceeding. Safety should always be your top priority when working with electrical wiring. Once the power is off, ...
A circuit breaker does the same thing as a fuse — it opens a circuit as soon as the current climbs to unsafe levels — but you can use it over and over again. The basic circuit breaker consists of a simple switch, connected to either a bimetallic strip or an electromagnet. The hot ...

Safety is paramount when it comes to testing and troubleshooting. Because the insulation resistance tester produces significant DC voltages, it can never be connected to an energized circuit. Also, the output of the tester can destroy electronic circuits. Never connect an insulation resistance tester ...
A lineman school (or lineman college) gives future linesman the knowledge and understanding of what a lineman does before applying to an apprenticeship. Budding lineman learn how to climb poles, how to use the tools of the trade, and learn day to day tasks of a lineman. ...
1.5V. If we switch the probes, we define ‘+’ as the common or zero point. How much voltage is there on the ‘-’ of the battery compared to our new zero? -1.5V! Now let's construct a simple circuit to demonstrate how to measure voltage in a real world scenario. The circuit is...
The above design appears to be a simple and an effective MOV tester circuit which can be quickly used to verify the clamping voltage of any MOV. It can be also used to verify whether the MOV is actually good or a bad one. The idea is simple, when we press the push button, the main...
