About this item

• [Short Circuit Tracking and Locating] In most cases, a short circuit or momentary overload of a component will cause a fuse or circuit breaker to blow. Using this auto test light can help you quickly and accurately find the faulty wire and its fault point
• [Polarity Identification & Continuity Testing] The power circuit probe tester is designed to rapidly determine the polarity (positive and negative) of vehicle cables and connectors. Upon contact with the positive terminal, the LED will illuminate in red, while touching the negative terminal will cause the LED to glow green. Additionally, the power circuit probe tester can be utilized for assessing the continuity of switches, relays, diodes, fuses, and various vehicle circuits.
• [157inch Test Cable] The automotive circuit tester is equipped with a 157inch extended testing cable wire, convenient for use and storage, along with large size alligator clip for easy one hand operation, making it easy to test the entire vehicle circuit system, which will definitely improve your working efficiency
• [Component Activate and Test] This power circuit probe tester is perfect for professionals and car enthusiasts, which can be used to activate components inside/outside the auto electrical system and the LED indicator light makes it easy to check whether the component is defective and test whether the rated current of the component is higher than the rated current of the car test light
• [Wide Application & Overload Protection] This power circuit probe tester is suitable for of all 6V to 24V automotive electrical systems which works well on cars, trucks, boats, trailers, and motorcycles. The tester also has an overload protection function, When the current exceeds 7A, the circuit will automatically disconnect and give out a buzzer prompt
