Automotive Power Circuit Tester with 4M Test Wire 6 24V DC LED Light Fuse 6V 12V Auto Electrical Tools

1. Portable Multi-Function Electric Tester The 4m extension cord is useful for mobile maintenance work and is suitable for diagnosing all automotive electrical systems from 6V to 24V. The tester is made of ABS material, which is resistant to moisture, high temperature, impact and has a longer service life. The tester also has an overload protection device. When the current exceeds 7A, the circuit breaker inside the device will automatically trigger and emit a sound prompt. 2. Polarity Test & Continuity Test The tester is made of insulating material and high-quality stainless steel, which can help you quickly identify the positive and negative polarity of the vehicle cable and socket. When the tester touches the positive pole, the LED should be red; when it touches the negative pole, the LED should be green. The electrical circuit tester is also used to check the continuity of switches, relays, diodes, fuses and circuits. 3. Activating and testing components for professionals or car enthusiasts, this continuity tester is a great tool. The automotive short circuit tester can activate the components coming in/out of the vehicle electrical system. The LED indicator and sound prompt can easily test and check whether the components are faulty, or whether the rated current of the component is higher than the rated current of the tester. 4. Automotive circuit tester for grounding test. The design of the circuit breaker is perfectly designed and comfortable. It is equipped with an extended 4m detection line, covering the front to the rear of the vehicle and easily detecting the entire vehicle circuit system. The automotive circuit tester kit has a grounding prompt device. If the LED indicator turns green and the buzzer sounds, it means that the grounding is good. If not, the LED remains red and there is no beep. 5. Short Circuit Tracking & Locating The electric tester uses advanced high-sensitivity probes to provide you with fast and accurate detection. Using the continuity tester can save a lot of time to troubleshoot the car wiring circuit, quickly and accurately find the faulty wire and its fault point. 6. 24 hours service and 1 year warranty. We provide this circuit probe tester with 24-hour friendly customer service and 12-month free warranty to ensure your shopping experience., Weight: 0.72973008722 Pounds, Manufacturer: CMTOOL
