Advanced Automotive Circuit Tester – Polarity and Continuity Detection This professionalgrade automotive circuit tester is designed for fast, accurate diagnosis of vehicle electrical systems. Ideal for mechanics, technicians, and vehicle owners, it combines polarity testing and continuity testing to quickly identify electrical faults, making troubleshooting easier and more efficient. Key Features and Benefits: • Polarity Detection – Easily determine electrical contact polarity. The tester displays a red LED when connected to the positive pole and a green LED when connected to the negative pole, providing instant visual feedback and reducing diagnostic guesswork. • Continuity Testing – Detect whether automotive circuits are continuous and identify short circuits. This helps locate wiring faults, broken connections, or damaged components before costly repairs. • Fast Fault Location – Test the onoff status of vehicle electrical systems within the 6–24V DC range. Quickly pinpoint faulty wires and their exact fault points, minimizing downtime and costs. • Reliable Performance – Designed for consistent and accurate readings in various automotive conditions, ensuring dependable results every time. • Easy Connection – Red clip attaches securely to the car battery positive terminal, black clip to the negative terminal. The auxiliary ground wire connects to the wire or component under test for precise measurements. How to Use: 1. Connect the red clip to the battery's positive electrode and the black clip to the negative electrode. 2. Press the 'Positive' button; the LED will turn red to indicate positive detection. 3. Touch the test tip to the positive terminal of the component being tested to activate it. 4. If the LED turns green, stop the test and check whether the component is faulty or if its rated current exceeds the tester's capacity. Practical Applications: • Diagnose power and grounding issues in car lighting systems. • Locate wiring faults in automotive accessories such as audio systems, dashboard electronics, and aftermarket installations. • Identify short circuits in trailer wiring or auxiliary vehicle equipment. Compatibility: • Works with automotive electrical systems operating between 6V and 24V DC. • Suitable for cars, trucks, motorcycles, trailers, and other DCpowered vehicles. Construction and Materials: • Durable, tester body and clips designed to withstand repeated use in workshop or field conditions. • quality LED indicators for clear polarity recognition in all lighting environments. Performance Advantages: • Speeds up electrical troubleshooting. • Reduces the risk of incorrect component handling. • Enhances accuracy by pinpointing exact fault locations. This circuit tester is an essential tool for anyone working with vehicle electrical systems, offering the precision, durability, and ease of use needed for professional or DIY automotive work.
