Circuit Tester, Electrical Circuit Tester, Car Electrical Tester with LED Light 6-24V

1. Easy to diagnose: This circuit probe is an electrical tester designed to reduce diagnostic time for automotive electrical systems. It comes with a 4m cable for easy testing. 2. Multi-purpose: The circuit tester can test continuity, polarity, ground connections, check switches, relays, diodes, fuses, and circuits, and trace and locate short circuits. 3. Safety tool: The automotive test probe is a useful tool for determining if power is present and also as a way to safely power fans, motors, and electrical circuits. 4. Quick identification: Helps you quickly identify positive and negative polarity. When the probe touches the positive terminal, the red light illuminates, and when the probe touches the negative terminal, the green light illuminates. 5. Wide application: Quickly and efficiently test electrical systems. Suitable for 6-24V systems, including cars, boats, trailers, relays, etc. Specification: Item Type: Car Circuit Tester Material: ABS - Stainless Steel Voltage: 6-24V Overload Protection: 7A (when the current exceeds 7A, it will automatically disconnect the power) Cable Length: Approx. 4m/13.1ft Function: Polarity Test Continuity Test Ground Test Short Circuit Tracer and Locator Testing of Components in the Vehicle Electrical System Testing of Components Outside the Vehicle Electrical System System Testing of Connecting Wires Self-Test Test the positive and negative polarity of contacts in the vehicle circuit: When the probe tip touches the positive terminal, the red indicator lights up. When the probe tip touches the negative terminal, the green indicator lights up. Multifunctional Activation of Vehicle Electrical System Components: When the component's control switch is on the positive side of the component, press the button on the negative side and the LED will light up red. Touch the probe tip to the positive terminal of the assembly. The component will be activated. Activating Components Outside the Vehicle's Electrical System: Using the probe tip with an auxiliary ground wire allows you to activate components, thus testing their functionality. Application: Universal. Instructions: 1. Unfold the device cable. 2. Attach the red clamp/holder to the positive terminal of the vehicle's battery. 3. Attach the black clamp/holder to the negative terminal of the vehicle's battery. Package List: 1 x Car Circuit Tester, 1 x Manual. Note: Please be aware that the new and old types of this product will be sent randomly, and ensure this is acceptable to you before ordering.
