Description: This car circuit tester is specifically designed for test automotive circuitry or electrical, it is equipped with AVO meter, test lamps, built-in lighting lamp, short circuit indicator, relay/component tester, continuity tester and poor ground contact indicator. It can quickly detect the power consumption and load of the automotive circuit, and enable users to check the circuit and automotive electronic components one step at a time. It is a diagnostic tool for every vehicle maintenance electrician. Features: Multi-language support: English, German, French, Russian, Spanish, Italian, Portuguese. Integrate LED flashlight on the head, let us work in dark condition easily. All the clips and cable were made from copper, improve stability during operation. Testing for continuity with its built-in auxiliary ground lead. By depressing the power switch, conduct a positive or negative battery current to the probe tip for testing the function of an electrical component without the use of jumper wires. Testing for poor ground contacts instantly without performing voltage drop tests. The tool is also short-circuit protected; its internal circuit breaker will trip if it becomes overloaded. Following and locate short circuits without wasting fuses. The tool's long cable allows you to test along the entire length of the vehicle without constantly searching for suitable vehicle grounds.
