Car Electrical Circuit Tester with LED Indicator Light 6V/12V/24V, Electrical System Analyzer, Car Tester with Probe

【Automotive Circuit Tester - Usage】Depending on the application, the electrical power tester can be connected in two ways. Direct connection: Extend the cables and connect the red clamp to the positive terminal of the battery, the black clamp to the negative terminal of the battery, and the ground clamp to the grounding point. Jumper mode: Keep the black and ground clamps connected, disconnecting only the red clamp from the battery. 【LED Indicators and Overload Protection】When the positive button on the automotive test lamp is pressed, the LED indicator turns red; when the negative button is pressed, it turns green. To prevent damage to the device, the car electrical circuit tester is equipped with an overload protection function that automatically cuts off the circuit when the current exceeds 8A. 【Multifunctional Automotive Tester】Our automotive electrical tester can be used to test external components, internal electrical systems, and jumper continuity. Test factors include polarity, continuity, insulation, signal strength, grounding, and operating current. With this car circuit tester, you can efficiently diagnose circuit faults! 【Portable Car Tester】This car electrical test lamp is lightweight and compact, making it easy to carry. The ergonomic design makes it comfortable to use by hand. The circuit detector for car diagnostics comes with a roll of electrical tape to help you insulate wires during repairs. 【Test Tester Applications】This automotive circuit tester operates with a voltage of 6 to 24V DC, in a temperature range of -10°C to 56°C, and is equipped with a 13.5-foot (4-meter) cable. The multifunctional car circuit tester allows you to test components such as lights, motors, relays, and fuses, making it easy to diagnose electrical problems on vehicles such as Volkswagen vans, classic cars, sedans, SUVs, motorcycles, and boats.
