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.” ...

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 ...

Be careful with single-phase motors, as most single-phase motors have components to help them start or continue to run ...

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.

The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

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 ...

Disconnecting the battery while the engine is running isn't a valid test for alternator function and may damage sensitive electronic parts. Instead, use a common voltmeter and the following test ...
