About this item

• 【ALL-IN-ONE 12V/24V Automotive Circuit Tester Kit】The VDIAGTOOL V200 power circuit probe tester can help you resolve vehicle electrical faults in minutes, no guesswork or complicated setup required. This all-in-one tester supports 12-24V systems and covers voltage testing, polarity check, continuity, ground testing, short circuit detection, component activation and more in one unit. It replaces a multimeter, test light, jumper wires to streamline your diagnostics. Simply plug and test, ideal for both beginners and professional technicians. Perfect for shop service, DIY troubleshooting and routine vehicle maintenance.
• 【4-IN-1 ADVANCED TEST MODES】This power tester is your ultimate diagnostic tool with 4 essential working modes: DC voltage (0.1V resolution), AC voltage (easily read Max/Min values, frequency & duty cycle), Resistance, and Diode. Instantly identify live wires and polarity to locate shorts or faults with precision. Unlike basic testers, our exclusive tone On/Off design lets you hear circuit voltage changes—perfect for noisy or brightly lit environments. Fast, intuitive, and built for pros who need real answers on batteries, fuses, alternators, wiring, and more. The VDIAGTOOL V200 Automotive Power Circuit Probe Tester is perfect for modern 99% cars, pickups, RVs, boats, and trailers.
• 【40FT TOTAL LENGTH TO REACH ACROSS TRUCKS, RVs & TRAILERS】 Tired of hauling tools around or squeezing under the dash due to short cables? The V200 power circuit probe includes a heavy-duty storage case, a 20ft main cable and a 20ft extension cord for a combined 40ft maximum reach. Perfect for servicing lifted pickups, travel trailers and boat trailer lighting systems. The integrated flashlight lights up dim work areas, streamlining under-the-hood and low-light troubleshooting. Compact and portable, ideal for shop bays, driveway DIY jobs and roadside emergency service.
• 【BUILT-IN OVERLOAD PROTECTION FOR SAFETY & DUAL POWER OPTIONS】Electrical diagnostics should never put your vehicle or tools at risk. The V200 power circuit probe tester features smart overload protection with an integrated 8-amp circuit breaker. It automatically shuts down and resets when overload occurs, safeguarding your tester and vehicle components. You can even leverage this function to trace short circuits intentionally. Run directly from your vehicle battery or cigarette lighter port—no spare batteries required, so it’s always ready for on-site troubleshooting.
• 【QUICK POLARITY DETECTION】The V200 power circuit probe kit enables fast identification of continuity, polarity and open circuits. Stop guessing! Touch the probe tip to a positive terminal, and the red LED activates with a beep; connect to negative potential, and the green LED glows with a low tone. No light indicates an open circuit. This intuitive tool simplifies ground checks and short-circuit tracing, perfect for chasing blown fuses and intermittent vehicle faults. Diagnose blown fuses in seconds and accurately pinpoint shorts. Comes with an alligator clip ground cable for stable resistance testing on external components.
• 【ACTIVATE COMPONENTS LIKE A PRO】The automotive circuit tester speeds up troubleshooting by sending activation signals to car lights, fuel injectors, windshield wipers, radiator fans, and relays without removing parts. Test components on the bench, in-vehicle, or with ground connections—ideal for DIYers and technicians tackling electrical gremlins. Quickly locate faulty components to avoid unnecessary part swaps, reduce wasted labor and cut repair costs by using the V200 circuit probe.
• 【CONTINUITY & SENSOR SIGNAL CIRCUIT TEST】This V200 circuit detection tool supports continuity checks and sensor signal diagnostics. Leverage AC Voltage mode to monitor sensor waveforms, verify ground connections, test continuity in seconds. No need to switch between multiple meters. Great for troubleshooting defective sensors and intermittent signal loss, so you can rapidly locate open circuits and damaged wiring harnesses.
• 【PORTABLE & RELIABLE】This Electrical System Probe Tester is built for professional technicians and DIYers. More intuitive than a standard multimeter, it delivers robust functionality with an ergonomic shape and user-friendly controls. Backed by a 2-Year Warranty, 30-Day hassle-free replacement & return service, lifetime technical support and free probe replacement. Feel free to reach out to us for any questions about the tester.
