In this article, I’ll show you how to use a multimeter to troubleshoot some basic electronic components, such as resistors.

What is a multimeter anyway? Multimeters are covered in cryptic symbols and buttons, but don't let that intimidate you. There are three basic functions you'll use most often: measuring voltage ...

Seriously, what setting do you use to test a spark plug wire? Which ports do the probes attach to? How do I measure alternating current voltage?

You can use them to test for voltage drop at various circuits, blown fuses, current draws, heating elements, and to verify bad cable connections. The most common task is checking pedestal voltage.

This video covers the essential steps to properly test a car's alternator and diagnose common alternator issues. The guide demonstrates how to check the voltage regulator, diode rectifier, stator, and ...

Record the voltage that appears on your multimeter. If your power supply sticker shows a voltage of 135 volts, you should be seeing the same reading on the multimeter.

Diagnosing a faulty transmission speed sensor is pretty straightforward, as is replacing it, but to diagnose a problem fully, you’ll need to be comfortable using a multimeter to check voltage.

Testing the DC voltage output of the power supply using a digital multimeter can help you isolate any potential issues and determine if you have a bad power supply.
