Feature(may vary by option.)

●1.【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 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.
●2.【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.
●3.【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.
●4.【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.
●5.【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.
●6.【24-Hour Service and 3-Year Warranty】We provide this circuit probe tester with 24 hours friendly customer service and 36 months free warranty to ensure your shopping experience. We always put our customers first, if you have any questions about this probe tester, please feel free to contact us!

Wide Application

This automotive test light is suitable for diagnosis of all 6V to 24V automotive electrical systems and works well on cars, trucks, boats, trailers and motorcycles.


Probe Tip Use the advanced high-sensitivity probe to quickly and accurately detect electrical system problems.	Extension Test Lead The cable length of the circuit tester is about 4m (13FT), and the extension cable is very helpful for mobile maintenance work.	Auxiliary Ground Clamp The black clip and auxiliary ground lead are connected directly through the unit. Users can consider it as a long jumper test lead by leaving the right clip disconnected from the battery.


Power Switch The portable and ergonomic design of the circuit tester is very helpful for you to use in narrow areas.	Two Clamps The clip with strong bite force is not easy to fall off, providing you with a better experience.	LED Indicator LED indicator lights and buzzer prompt help you accurately determine the automotive electrical system problems and reduce the time for diagnosis.


Component Activation and Testing Activate components in/Out of the vehicles electrical system.	Grounding Test lt can detect whether the component has a large current flow, and test whether the negative grounding of the component is good.	Track and Locate Short Circuits Save a lot of time to troubleshoot car wiring circuit faults, quickly and accurately find faulty wires and their fault points.


Overload Protection When the current exceeds 7A, the internal circuit breaker of the tester will automatically trip and issue a buzzer prompt .	Polarity Test Help you quickly identify the positive and negative polarity of vehicle cables and plugs.	Continuity Test Help you quickly test the working status of switches, relays, diodes, fuses and circuits.

FEATURES	This kit can be used with any multimeter and oscilloscope probe extension cables for diagnosing, testing and repairing complex vehicle circuits. It can also troubleshoot sensors, actuators and electronic circuits.	This kit easily releases terminals from the plastic connector housings on every electrical connection on your vehicle or computer. It eliminates damage to wires or terminal blocks, making it safer and more efficient.	Helps you quickly and accurately determine the condition of the vehicles exhaust system, which can prevent sluggish engine performance, reduced acceleration, and excessive heat.	Used for coolant vacuum filling and vacuum pressure testing. Using this tool to replace coolant can avoid poor coolant circulation caused by air entering the radiator.	The kit has the most common sizes in UNC, UNF, and metric. Cleans internal and external threads. The thread chaser set is great for cleaning up crusty, rusted and damaged threads.	This tool can clean the entire fuel system, including the throttle valve, fuel nozzle, combustion chamber, fuel injector, intake system and three-way catalytic converter.
