Features
【Power Probe Circuit Diagnostic Tool】This multifunctional circuit tester can check switches, relays, and the on-off status of diodes, fuses, and circuits, which helps reduce diagnostic time in automotive electrical systems.
【Portable Multifunctional Electrical Tester】The 4-meter extension cord facilitates mobile maintenance work. The tester is made of ABS material, which is moisture-proof, high-temperature resistant, impact-resistant, and offers a longer service life.
【Polarity/Continuity Test】This power circuit probe tester helps quickly identify the positive and negative polarity of electric cables and plugs in vehicles. When the probe tip contacts the positive electrode, the RED light turns on. When it contacts the negative electrode, the GREEN light turns on. It can also test continuity and perform jumper lead operations with the assistance of its auxiliary ground lead.
【Short Circuit Tracking and Locating】This probe tester assists in tracing faulty wires and locating break points. Simply connect the clips to the vehicle battery correctly and quickly touch the probe tip to the wire. If the LED lights GREEN with a buzzer sound, a short circuit or overloaded component is detected on this side.
【Self-Test & Overload Protection】Before testing a circuit or component, the test light can perform a quick self-test to ensure the tool is in good condition. Equipped with overload protection, when the current exceeds 7A, the circuit tester automatically disconnects the current and provides a buzzer prompt. Poor ground contacts can be tested directly.
【Easy Operation Circuit Tester】Unroll the leads. Clamp the red clip to the positive terminal of the vehicle's battery and the black clip to the negative terminal. After connecting the circuit tracer to the battery, the automotive technician can conduct positive or negative battery current to the tip by rocking the power switch forward or backward.
【Wide Compatibility】It works with all 6–24V DC vehicle electrical systems. The 13-foot extension cord allows access anywhere in cars, trucks, and trailers, enabling testing along the entire length of the vehicle without frequently searching for suitable grounding points.
