2. Test for continuity with its built-in auxiliary ground lead.

3. By depressing the power switch, conduct a positive or negative battery current to the probe tip for testing the function of an electrical component without the use of jumper wires.

4. Test for poor ground contacts instantly without performing voltage drop tests. The tool is also short-circuit protected, its internal circuit breaker will trip if it becomes overloaded.

5. Follow and locate short circuits without wasting fuses. The tool's long cable allows you to test along the entire length of the vehicle without constantly searching for suitable vehicle grounds.
