OBDResource Voltage Tester Car Circuit Tester, 0V-80V DC Car Voltage Tester with Power Circuit Probe Digital Screen for Testing Car Battery/Continuity/Grounding/Polarity/Diode/Lamp

Multi-Functional Car Voltage Tester: It can test voltage and polarity of battery, continuity of car circuit, locate the short circuit, components of car (lamp, trail light, etc;) and the grounding condition. You can also repair or inspect the circuit with jumper operation. With this instrument in hand, you no longer have to worry about any electrical problems of car circuits.You can keep it at home to quickly check the car's wiring and components. Brighter Headlights and Screen: The 2 front lights can illuminate dark place of your car once the tester is connected to the car battery. Every corner of the car can be tested while the length of the lead is up to 5 metres. The digital acrylic display and polarity indicator allow you to intuitively determine the status and voltage of the test lead. Not only in the dim place, but also in direct sunlight, the data can be read clearly on the screen. Quick Testing of Components: With the power circuit probe and alligator clip, you can control the probe to output a positive or negative voltage by pressing the button. So it can test vehicle components such as lamps offline, or to test components by connecting them to the vehicle wiring. The automotive voltage tester also supports jumper operation, which can jump over the original line to check or locate the short circuit. Grounding Test and Buzzer: Some components require good grounding of the negative iron part, and a voltage tester can check the integrity of the component grounding. If the grounding is good, the buzzer will sound and the polarity indicator will turn green, if the grounding is bad, the polarity indicator will remain red and the buzzer will not sound. The buzzer will sound whenever the contact negative path is good. Wide Applications: The test lamp kfz is compatible for 0V-80V DC voltage environment, which can test circuit or components (Especially the spark plugs.) on cars, pickup trucks, SUVs, motorbikes, construction vehicles and boats. If a vehicle's electrical system fails, a voltage tester can be used to quickly detect and identify the problem, making it the right tool for drivers to always have on hand!
