About this item

• 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
• Polarity and Continuity Testing: This automotive electrical tester features an insulating body and a durable stainless steel probe, allowing for swift identification of the positive and negative sides of vehicle wires and connectors. When the tester contacts the positive element, the LED will illuminate red; conversely, contact with the negative side will light up the LED in green. Additionally, this power circuit probe is capable of assessing the continuity of switches, relays, diodes, fuses, and various circuits.
• 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
• Component Activation and Testing: The auto voltage 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
• 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
