  • Wide Voltage Compatibility & Comprehensive Functions:Designed for 6-30V automotive power circuits, this diagnostic tool integrates 7 core functions - voltage detection (1-60V range), positive/negative pole identification, component activation (0-8A max current), continuity testing, grounding detection, trailer light/connector testing, and short circuit tracing. It efficiently diagnoses short circuits, broken wires, and poor contacts in vehicle electrical systems
  • Safe & Reliable Operation:Equipped with reverse polarity and overload protection; the device triggers trip protection (with alert tone) when current exceeds 16A. Features LED indicators and a digital display for clear test results, plus an LED work light for dark environments. Complies with safety standards, requiring no operation while driving and ensuring proper ventilation during use
  • Easy to Use with Quick Self-Test:Simple setup - connect battery clamps to the vehicle battery for power. The quick self-test function verifies device functionality before use. Intuitive controls: forward switch for positive voltage output, backward switch for negative voltage, and clear color-coded lights (red for positive, green for negative) for instant status recognition
  • Versatile Application Scenarios:Ideal for activating automotive components like starters, fuel pumps, solenoid valves, cooling fans, and headlights. Suitable for testing trailer lights/connectors, acting as a jumper lead, and locating short circuits by tracing wire harnesses. Perfect for professional mechanics and DIY vehicle enthusiasts
  • Durable & Compact Design:Built with high-quality materials to withstand operating temperatures of 0~60°C and storage temperatures of -40~70°C. Compact size (78*145mm) for easy portability and storage. The outer casing is easy to clean with a mild detergent, keeping the tool free from oil, water, and grease
