6V-24V DC Wide Voltage Range digital circuit tester for automotive electrical systems. This device is designed to accurately test circuits in vehicles with a voltage range of 6V-12V-24V DC, making it suitable for diagnosing issues in car headlights, taillights, turn signal circuits, faulty sockets, connections, and various wires within the 6-24V range. Key benefits - Quick and reliable circuit diagnosis across 6V-24V DC systems, including common 6V, 12V, and 24V automotive applications. - Clear readout with a red digital display that shows voltage results, enabling easy interpretation on the go. - Visual confirmation of circuit connections via an indicator light on the handle, improving testing confidence. - Secure and consistent contact during probing thanks to the anti-bending tail wire. Core features - Wide voltage compatibility: test circuits in vehicles that operate within 6V-24V DC. - Indicator light and digital readout: the handle-mounted indicator lights up when a circuit connection is established; a red digital display presents the test voltage clearly. - Anti-bending tail wire: designed to maintain secure contact during tests and reduce fatigue on the cord. - 7 ft PU spring wire: flexible, lightweight, and durable for comfortable, versatile testing in tight spaces. - Large-size alligator clip: enables one-handed operation for convenience and efficiency. - Sharp stainless steel probe: precisely pierces wires and reaches tight or hard-to-access areas. - Durable construction: heavy-duty test light body made of high-quality ABS material, providing shatterproof and long-lasting performance. What’s included and build quality - The tester includes a 7 ft PU spring wire for flexible connectivity and easy reach across automotive layouts. - All components are housed in a sturdy ABS body for reliable performance in workshop or field environments. - The sharp stainless steel probe ensures accurate access to wires while maintaining structural integrity during repeated use. Practical use scenarios - Diagnosing lighting circuits: quickly test car headlights, taillights, and turn signals to determine if the circuit is delivering the correct voltage and if wiring or sockets are functioning properly. - Inspecting connections and sockets: verify continuity and identify loose or faulty connections within the 6-24V range. - Accessing confined spaces: use the sharp probe to pierce insulation and reach wires hidden behind panels, dashboards, or within crowded engine bays, while maintaining secure contact with the circuit.
