A multimeter is a powerful tool for measuring electrical values such as voltage, resistance, and current, commonly used in automotive and household applications. This beginner’s guide will walk you ...

Testing is accomplished by touching the multimeter's negative probe to a good ground and touching each blade. Since the fuse is a small conductor, one should expect 12 volts on either side.

It's a must-have for any toolbox—but there's a learning curve involved. Learn how to use a multimeter for all of your electrical testing needs.
