Electrical snafus are among the most annoying problems with older cars. Unlike tires or bodywork, there's something about electrical systems that seems to baffle many car crafters. We could blame it ...

Because of its mass, a battery takes a long time to change temperature. If a vehicle sits out all weekend in a zero-degree environment, it might take 30 hours to warm up the battery. Use the outside ...

Electrical equipment that operates below its voltage rating can overheat or power down. Here's how to determine your load's operating voltage. Voltage drop across switchgear and feeder and branch ...

All Amped Up! - The Demand for Add-On Electrical Components is Increasing and so is the Load on the Charging System You just finished installing a dual, 12-inch ...

We recently purchased a low-mileage 1967 Dart from Albany, New York. Over the years, electrical systems tend to be updated, either by a genius or a dunce, and the previous owner (fifth titleholder) ...

The digital voltmeter is the best basic tool for electrical troubleshooting, because it's calibrated and exact. But remember, the digital voltmeter can't detect a high-resistance fault if the circuit ...

As a fundamental concept of electronic design, voltage drop ranks highly as one to understand well. I particularly appreciate when industry folks come up with creative ways to get the point across.

Inevitably, industrial facilities are going to have 460VAC, 3-phase motor loads. And, of course, since voltage drop is considered mainly a performance issue, maximum voltage drop rules on a circuit ...

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 ...
