Power supply circuit probe kit, 6-24V car function tester, with LED light, circuit detector, voltage tester, electrical system test light tester

Highly Professional Testing Device: The power circuit probe kit can be used to test continuity, voltage polarity, lights, motors, trace and locate short circuits, test for poor ground connections, and more.

Positive-Negative Testing Function: The digital automotive tester is made of insulating material and features a high-quality stainless steel tip that can help you quickly identify the positive and negative polarity of vehicle cables and connectors. When the DC circuit tester touches the positive terminal, the LED indicator should be red; when it touches the negative terminal, the LED indicator should be green.

Audible Alarm and LED Indicator, High-Safety Probe: The circuit tester uses advanced, high-sensitivity probes and clips, enabling fast and accurate testing and providing a better user experience.

The automotive test lamp also features overload protection; if the current exceeds 7A, the device's circuit breaker will automatically trip and emit a beep. Short-circuit detection: The unit has a short-circuit protection function that can immediately detect a poor ground connection. The intelligent automotive circuit tester adopts an advanced, high-sensitivity probe to provide fast and accurate detection, quickly and precisely locating the faulty wire and its point of failure. Wide application: This car voltage tester is suitable for diagnosing 6V to 24V automotive electrical systems. Please do not use it under AC voltage. The car circuit tester can operate correctly on cars, trucks, boats, trailers, and motorcycles.
