CMTOOL Power Circuit Probe Tester 6V-24V DC Test Light, Automotive Circuit Tester Car Short Finder, Component Activation, Polarity Identify, Overload Protection

Features

• 【Wide Application & Overload Protection】The power circuit probe tester is made of ABS material, which is moisture-proof, high-temperature resistant and has a longer service life. It is suitable for diagnosis of all DC 6V to 24V automotive electrical systems and can work well on cars, trucks, boats, trailers, and motorcycles. The tester also has an overload protection device, When the current exceeds 7A, the circuit breaker inside the device will automatically trip and give out a buzzer prompt.
• 【Polarity Test & Continuity Test】The power circuit probe tester is made of insulating material and high-quality stainless steel tip, which can help you quickly identify the positive and negative polarity of the vehicle cable and plug. When the dc circuit tester touches the positive pole, the LED should be red; when it touches the negative pole, the LED should be GREEN. The power circuit probe tester is also used to check the continuity of switches, relays, diodes, fuses, and circuits.
• 【Component Activation and Testing】The automotive power circuit probe tester can activate components inside/outside the vehicle electrical system, perfect for professionals or car enthusiasts. The LED indicator light and buzzer prompt make it easy to test and check whether the component is defective or whether the rated current of the component is higher than the rated current of the car test light.
• 【Grounding Test & 4M Test Lead】The electric circuit tester has a ground prompt device, if the LED indicator turns green and the buzzer sounds, it means the ground is good. If not, the LED remains red and does not beep. The automotive circuit tester is equipped with a 4M extended detection line, covering the front to the rear of the vehicle, making it easy to test the entire vehicle circuit system.
• 【Tracking and Locating Short Circuit】The power circuit probe tester uses advanced high-sensitivity probes to provide you with fast and accurate detection. Using this automotive test light can save a lot of time to troubleshoot the car wiring circuit, to quickly and accurately find the faulty wire and its fault point.
