Electrical Circuit Tester, 6-24V DC, 12V Automotive Test Lamp with 5m Cables, Circuit Breaker Detector for Continuity Testing in Cars, SUVs, and Trucks

Automotive Circuit Tester: This professional 12V electrical circuit tester diagnoses the electrical systems of various vehicles, such as cars, motorcycles, and trucks, across a DC voltage range of 6 to 24V.Powerful, it supports various tests such as polarity testing, continuity testing, short-circuit tracing, component activation, and ground testing, making even complex circuit problems unsolvable. Positive and Negative Circuit Detection: The metal probe on the front of the electrical circuit tester quickly identifies the charge and polarity of each unknown contact point in the automotive circuit.Quickly identify the current state of the automotive circuit and ensure safety.A red light indicates a positive charge (+) and a green light indicates a negative charge (-). Continuity Test: This electrical tester allows you to check for open circuits or loose connections in automotive components, for example, if a fuse is blown, and to verify the proper connection of switches and relays.This test is safe enough and will not damage sensitive components (ECU, sensors, etc.). Component Activation: This automotive circuit tester can be connected to a circuit to quickly check or activate specific components, such as starters, fuel pumps, cooling fans, headlights, blowers, etc.If faults are detected during inspection, or if the rated current of the components exceeds that of the vehicle's test indicator, an audible alarm will sound. Safety and robustness: The 12-volt test pen is ergonomically designed for the human body.Its surface is made of high-quality ABS, which is very soft and absorbent!The grip is designed for a perfect fit.It fits comfortably in the palm of your hand, making it easy to hold and preventing it from slipping.The tester is also equipped with a 5-meter cable, allowing you to easily test all the vehicle's circuits.
