Product Description

Power Circuit Probe Tester, DC 6V~DC 24V Circuit Tester with LED Test Light Automotive Circuit Breaker Finder with 4M Lead, Car Electrical Tester, Polarity Test/Component Activation/Overload Protection
Power Circuit Probe Tester
Portable Multifunctional Electrical Tester
The 4-meter extension cord is helpful for mobile maintenance work and is suitable for diagnostics of all 6V to 24V automotive electrical systems. The tester is made of ABS material, which is moisture-proof, high-temperature resistant, impact-resistant 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 trip and give out a buzzer prompt.
Polarity Test and 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 plug. When the tester touches the positive pole, the LED should be red; when it touches the negative pole, the LED should be GREEN. The electric circuit tester is also used to check the continuity of switches, relays, diodes, fuses, and circuits.
Electrical Tester for Component Activation and Testing
For professionals or car enthusiasts, this continuity tester is a great tool. The automotive short circuit tester can activate the components in/out of the vehicle's electrical system. The LED indicator and buzzer prompt can easily test and check whether the components are defective, or whether the rated current of the component is higher than the rated current of the tester.
Automotive Circuit Tester for Grounding Test
The design of the circuit breaker finder is perfectly designed and feels comfortable. It is equipped with a 4M extended 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 it is not, the LED remains red and there is no beep.
Tracking and Locating Short Circuits
The electrical 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, to quickly and accurately find the faulty wire and its fault point.

Components Name Introduction
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.

Function Testing
Component Testing & Functional Applications
  • Component Activation and Testing: Activate components in/Out of the vehicle's electrical system.
  • Grounding Test: It 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.

Frequently Asked Questions (FAQ)
What voltage range is this power circuit probe tester compatible with?
This circuit tester is designed to support diagnostics on all DC 6V to DC 24V automotive electrical systems, making it highly versatile for various vehicles.
How does the built-in overload protection safeguard the device?
The tester features an integrated circuit breaker. When the current exceeds 7A, the breaker inside the unit automatically trips and sounds a buzzer prompt to prevent damage.
How does the LED light assist in polarity testing?
During a polarity test, the LED light changes colors to indicate electrical states: it turns RED when touching the positive pole and GREEN when touching the negative pole.
What is the length of the test lead, and is it suitable for large vehicles?
It comes with a 4-meter (approximately 13 feet) extension test lead, allowing you to easily test the electrical circuits from the front to the very back of the vehicle.
How do I perform a grounding test with this circuit tester?
The tester has an integrated grounding prompt. If the LED indicator turns green and the buzzer sounds, it indicates the grounding is good. If the LED remains red and no buzzer sounds, the grounding is poor or disconnected.
Can this tester activate electrical components directly?
Yes, it can activate electrical components both inside and outside the vehicle's electrical system, allowing you to test if the component operates properly or if its draw exceeds the rated capacity.
