A multimeter is a helpful tool for advanced electrical projects. But multimeter symbols and their meanings can be cryptic to ...

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

Proper safety procedures are critical when testing high-voltage systems. As the following examples prove, mistakes happen. However, when the safety of you and your coworkers is at stake, neglecting ...

The alternator is responsible for charging the car battery and powering all the car's onboard network consumers. If it fails or is unstable, the battery will either not be charged or start discharging ...

You can use a multimeter with capacitance-measurement capability to measure the length of wire or cable to an open circuit. The capacitance of a pair of wires (or a wire to a shield) is directly ...

The circuit was developed to produce a continuity tester with a low resistance mainly for checking the connections between soldered joints. Operational Amplifier (Op-Amp) – a DC coupled high gain ...

When your car doesn’t start, often a low or dead battery is the culprit. Unfortunately, most vehicle owners do not check their battery until it fails. As preventative maintenance, the suggested best ...
