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 ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Q: Hello, Vette. I am a guy that likes to work on my own car and I just wanted to say thanks for all of the DIY articles that you publish. Well, let’s get to it. I have a 1997 C5 Corvette with very ...

The NEC provides a recommendation on voltage drop for branch circuits in Informational Note No. 4 following 210.19(A). A similar recommendation for feeders exists in Informational Note No. 2 following ...

Thank you for visiting one of our most popular classic articles. If you’d like to see updated information on this topic, please check out this recently published article, Low-Voltage Motors, Voltage ...

The opening part of this series laid out how the starter motor works, set the thing in the context of its electrical supply and suggested a few eyes-and-ears checks as the first steps in ...

At one time a relatively infrequent occurrence, voltage drop is now a major impediment to reliability at advanced nodes. Decades ago, voltage drop was only an issue for very large and high-speed ...
