Car Electrical Circuit Tester LED Warning Lamp 6V/12V/24V, Electrical System Analyzer, Auto Tester with Probe

【Automotive Circuit Tester - Usage】Depending on the usage situation, the electrical power tester can be connected in two ways. Direct connection: Extend the cables and connect the red clamp to the positive battery terminal, the black clamp to the negative battery terminal and the ground clamp to the grounding point. Jumper Mode: Keep the black and ground clamp connection unchanged, disconnecting only the red clamp from the battery.【LED Indicators & Overload Protection】 By pressing the positive button of the automotive test light, the LED indicator turns red; when pressing the negative button, 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 auto electrical tester can be used to test external components, internal electrical systems and jumper continuity. Test factors include polarity, continuity, insulation, signal, grounding and operating current. With this car function tester, you can effectively diagnose circuit faults!【Portable Auto Tester】This car electric test lamp is lightweight and compact, easy to carry. The ergonomic design makes it comfortable to use by hand.The supply of the circuit detector for car diagnostics includes a roll of electrical tape to help you insulate the cables during repairs.【Witness 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.
