CONTINUITY TESTING
Checking “continuity” is one of the most common tests in electrical troubleshooting. Continuity is the ability of a wire or electrical component to
conduct
current. When you use a continuity tester, you connect a circuit (the continuity tester) that you know works, to a wire or a component that
may or may not work.
The continuity tester will tell you if the wire or component is capable of conducting current.
Continuity testers are available at almost any hardware store.
A volt-ohmmeter or VOM can also be used to check continuity. This meter can be purchased at most electrical or electronic supply stores.
To test a component for continuity:
1 Check the tester by connecting the leads.
* If using a test light the light should turn on.
* If using a digital volt-ohmmete
r, the screen should show 00 if OL appears the meter needs to be repaired.
