- 【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.
- 【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.
- 【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.
