## Description

VDIAGTOOL V200 Automotive Circuit Tester, Power Circuit Probe Tool, 12-24V Electrical Short Open Breaker Circuit Finder, AC/DC Current Resistance, Duty Cycle, & 20FT Extension Cord, for 99% Cars

## Features

- 【ACCURATE ELECTRICAL TESTER KIT】V200 power circuit probe tester is a simple but extremely useful circuit tester with 20ft+20ft extension cable to check whether car circuits or a certain component is energized or not. It supports ✔Tracing Wire ✔AC/DC Voltage Test ✔Diode, Resistance Test ✔Polarity Test ✔Continuity,Ground,Signal Circuit Test ✔Activate Components ✔Relay,Fuse,Trailer Light Test ✔Locate Short Circuits ✔Circuit Breaker Protection on all electrical systems of 12-24V vehicles.
- 【4 WORKING MODES】This auto power circuit probe tester supports 4 working modes: DC voltage (0.1V Resolution), AC voltage(for reading Max & Min Voltage, frequency & duty cycle easily), Resistance and Diode. It can tell you instantly whether the wire or circuit is live and which side of the circuit you are on, positive or negative. The unique tone On/Off Design allows you to judge the circuit voltage according to the volume of the sound in bright areas, which is intuitive & useful for working.
- 【COMPONENT ACTIVATION】V200 automotive circuit tester will help you accurately judge whether the component is intact. The component activation feature is designed to generate activation signals to the tested components, such as car lights, motors, windshield wipers, radiator fans, relays, fuel injectors, and other on/off-board electric equipment to troubleshoot electrical problems. With this electrical tester, you can activate components in your hand/vehicle/ with ground, etc.
- 【IDENTIFY POLARITY QUICKLY】 VDIAGTOOL automotive probe tester makes it easy to check component continuity and identify positive, negative & open circuits. If the probe tip connects to the positive terminal, the RED LED lights on with beep sounds; If the probe tip connects to the negative terminal, the Green LED lights on with a low tone. Neither LED Lights up when it is an open circuit. You can also use this circuit tester to locate short circuits in your car if you keep getting blown fuses.
- 【CONTINUITY, SENSOR/SIGNAL CIRCUIT TEST】With the press of a switch, you'll have an instant hot lead or ground lead. Using the alternating voltage mode of the automotive electrical tool, you can check the state of sensors, do continuity tests, judge the the connectivity of circuit via the transmitted signal and check the resistance of various sensors and issues, checking for the good and bad grounds. V200 will be an essential electrical tester for tracking circuits and identifying broken parts.
- 【OVERLOAD PROTECTION】V200 power circuit probe kit has a built-in 8-amp circuit breaker for short circuit protection. Whenever it is overloaded, it just gonna shuts down and restarts, which is a safe measure to protect the device and your components from overload. Additionally, this automotive electrical tool is powered by the vehicle’s battery or cigarette lighter, ✔NO extra battery is needed.
- 【TOTAL 40FT CORD & BUILT-IN FLASHLIGHT】V200 circuit probe tester comes with 20FT cord plus 20FT extension cord, which allows you to reach from front to rear of the vehicle along the entire length of the vehicle without searching for a suitable ground easily. There is also cable with an alligator clip for an exhilarating ground connection, allowing you to test resistance on the components outside of the vehicle. Besides, the built-in flashlight is bright enough to light up your work area.
- 【PROFESSIONAL AFTER-SALE SERVICE】VDIAGTOOL V200 automotive electrical circuit tester comes with multiple efficient functions and intuitive interface with an ergonomic design, which will be the best gift for DIYers or pro-circuit repairers, electricians and technicians. We offer 3 Years Wa*rranty, Lif*e*time technical assistance, 60 Days No-Reason-asked Re*turn for re*fund and probe replacement for fr*ee.
