You can test a continuity or multimeter by touching the probes together and checking for the light or moving needle.

If the light switch is in good order the multimeter will now read a resistance value close to zero. In my case, I logged 0.4 ohm for an old 3-way switch I know works just fine.

For all of you who have a multimeter thrown in a drawer or toolbox but don’t know how to use it, these instructions will help in your search for missing voltage.

Can't you hook up a test light on the positive side of the motor, then the other lead to ground? If the light lights up, you've got power up to the motor.

A multimeter or digital multimeter (DMM) is one of the most essential and common pieces of lab equipment. Multimeters are used for taking basic electrical measurements related to Ohm’s Law.

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