Using a test light

Troubleshooting electrical problems is easy, first connect the ground clip to a known good ground source, the battery negative terminal is best but any grounded metal source will work. Then connect the pointed end of the test light to desired circuit to be tested. If power is present, the testlight bulb will illuminate.
