      Quickly diagnose breaks in automotive electrical connections with circuit testers from Grainger. They trace the wiring path or grounding points of circuits. If headlights are not coming on a circuit tester can trace the wiring path to find out what's wrong. Test the positive voltage on batteries by attaching one end to known ground and other to wire you want to test.
