[Polarity Testing & Continuity Testing for Automotive Circuits]: This advanced circuit tester, a must - have for automotive electrical work, is specifically designed to detect the uncertain contact polarity in vehicles. As a reliable polarity tester, it shows a red light when touching the positive pole and a green one when touching the negative pole. Moreover, functioning as a power short - circuit finder, it can conduct crucial continuity testing. This helps in determining whether the automotive circuit is continuous and if there are any short - circuits, making it an essential tool for diagnosing electrical issues in cars.
[Quick Fault Tracking and Locating with Circuit Tester]: Ideal for automotive electrical systems, this circuit tester is engineered to test the on - off condition of the automobile electrical setup under a 6 - 24V DC voltage. In the automotive world, a short - circuit or momentary overload of a component often leads to a blown fuse or circuit breaker. When this happens due to a short - circuit, this efficient circuit tester enables you to quickly and accurately locate the faulty wire and its exact fault point, saving you time and effort during vehicle repairs.
[Important Pre - test NOTE for Circuit Tester]: Before starting any test with this circuit tester, always ensure proper connection. Connect the red clip firmly to the positive terminal of the car battery, followed by connecting the black clip to the negative terminal. During continuity testing, attach the auxiliary ground wire to one side of the wire under test. When testing components either inside or outside the vehicle's electrical system, connect the auxiliary ground wire to the negative pole of the component being tested for accurate results.
[Simple How - to - Use Guide for Circuit Tester]: Using this circuit tester is straightforward. First, clip the red clip to the positive electrode of the car battery and the black clip to the negative electrode. Then, press the button on the “Positive” side, and the LED will light up red. Next, connect the tip to the positive terminal of the tested component to activate it. If the LED turns green, it's a sign to stop the test. At this point, check whether the component is defective or if its rated current exceeds that of the circuit tester.
