1. Determine at a glance whether the circuit is positive, negative or open, without the need to reconnect the clip from one battery pole to the other. 2. Test continuity through the built-in auxiliary ground wire. 3. By pressing the power switch, positive or negative battery current is conducted to the probe tip to test the function of electrical components without using jumpers. 4. Without the voltage drop test, immediately test for poor grounding. The tool also has short-circuit protection; if the internal circuit breaker is overloaded, it will trip. 5. Follow and locate short circuits without wasting fuses. The long cable of the tool allows you to test along the entire length of the vehicle without having to constantly search for a suitable vehicle ground.
