About this item

• Wide Application & Overload Protection: The power circuit probe tester is made of durable material, which is moisture-proof, high-temperature resistant and has a longer service life. It is suitable for diagnosis of all 0V to 80V automotive electrical systems and can work well on cars, trucks, boats, trailers, and motorcycles. Suitable for spark plugs. The tester also has an overload protection device, When the current exceeds 8A, the circuit breaker inside the device will automatically trip and give out a buzzer prompt
• Polarity Test & Continuity Test: The automotive electric 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
• Product advantages: Our test light circuit tester adopting acrylic display screen, this automotive circuit tester displays more clearly under strong light.The button of the circuit probe tester can be pulled out. After the device is short circuited and burned out, the button can be directly replaced to continue using, which is convenient for maintenance
• Component Activation and Assessment: The automatic voltage tester is capable of activating components both within and outside the vehicle's electrical system, making it an ideal tool for both professionals and automotive enthusiasts. The integrated LED indicator and buzzer signal facilitate simple testing to determine if a component is faulty or if its rated current exceeds that of the car's test light.
• Grounding Test & 5M Test Lead: The electric circuit tester has a ground prompt device, if the LED indicator turns green, it means the ground is good. If not, the LED remains red. The automotive circuit tester is equipped with a 5M extended detection line, covering the front to the rear of the vehicle, making it easy to test the entire vehicle circuit system
