Q: The left taillight on my pickup is somewhat dimmer than the one on the right side. It’s not bad enough to go through the trouble and expense of having fixed it. But it bugs me. Any chance you have ...

Master your alternator and regulator testing skills Knowing how to test your alternator and voltage regulator with a multimeter can save you from costly repairs and roadside breakdowns. With the right ...

For an efficient design, the conductor ampacity tables in Chapter 3 of the National Electrical Code (NEC) provide a starting point. But did the installation stay efficient over time? One way to ...

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 ...

Don’t be one of those people who saves money by sizing conductors only as large as you have to (by Code), but then turns around and recommends a big investment in a new lighting system to save energy.

There’s no doubt that cheap digital calipers are useful, especially when designing 3D-printed parts. Unfortunately, cheap digital calipers are also cheap, and tend to burn through batteries quickly.

What type of equipment is best to use for low-voltage test of battery cells? What is an electronic load, and how does it work? How to overcome a major limitation with the low-voltage-discharge test.

Most engineers think that using a power supply is a pretty simple task. But as currents go up, keeping the correct voltage on the device under test (DUT) can become a challenge. As current flows ...

Using longer cord lengths in an electrical design can introduce challenges significant enough to create potential safety risks. When cable lengths reach 50 feet or more, voltage drop becomes a concern ...
