Last week, I stepped through the basics of automotive electrical circuits, explained how electrical current needs to flow ...

The reality is that like almost every component under the hood, a car battery has a finite lifespan and will conk out on you eventually. Weather conditions, corrosion, electrical shorts, charging ...

In this video, learn how to check and test a battery to determine its condition, ensuring you or a family member never gets ...

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, ...

While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Car batteries tend to die at the most inconvenient moments, so periodic testing is the best way to avoid these troubles. Knowing what causes repeated battery failures can help you stay ahead of the ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

While many articles have been written about cell testing in R&D labs or cell testing during manufacturing in the factory, let’s turn to the topic of cell testing for incoming inspection. This article ...
