VDIAGTOOL V200 PRO Upgrade Kit Automotive Power Circuit Probe Tester with 30PCS Back Probe Kit, 12/24V Electrical Short and Open Circuit Finder AC/DC Voltage Test Activating Component 40Ft Cable

The media could not be loaded. The VDIAGTOOL V200 PRO is an impressive and affordable alternative to higher-end automotive circuit testers like the Power Probe. It delivers a full suite of diagnostic capabilities—including voltage, continuity, polarity, resistance, and wire tracing tests—making it a versatile tool for both professionals and DIY users.What sets it apart is the value: it includes a comprehensive 30-piece accessory kit, and thoughtful design features like a long extension cable and multiple power options significantly enhance usability. Real-world testing across trailers SUV confirmed its accuracy, durability, and ease of use.I used the Breaker Finder successfully in recessed compartments of modified utility trailers that I would have otherwise had to disassemble to get to the wiring. I believe that finding broken wires in this manner saves so much time. I have also used it to test LEDs in malfunctioning headlights. I imagine that this will aid in hard wiring dash cams (several upcoming installs) as well.For anyone seeking a reliable, cost-effective solution for automotive electrical diagnostics, the V200 PRO is a smart investment.

The VDIAGTOOL V200 Pro has significantly enhanced my approach to diagnosing vehicle electrical systems. Its comprehensive features, including AC/DC voltage testing, resistance and diode checks, and the ability to activate components like lights and fans, have made troubleshooting more efficient. The breaker finder function is particularly impressive, allowing for quick identification of open circuits and wire breaks without damaging insulation.The tool's design is user-friendly, featuring a clear TFT display and an intuitive interface. The 40-foot combined cable length provides ample reach around any vehicle, and the built-in flashlight is a thoughtful addition for working in dimly lit areas. Safety is also a priority, with built-in overload protection that automatically resets to prevent damage to both the tool and the vehicle's electronics.While the user manual could be more detailed, especially for those new to automotive diagnostics, the tool's functionality is straightforward enough to overcome this minor shortcoming. Overall, the V200 Pro offers exceptional value and performance, making it an indispensable asset for both professional mechanics and DIY enthusiasts.

I recently purchased the VDIAGTOOL V200 Pro to help with the install of hard-wired dash camera kit. (If you don’t have a dash cam – get one! Hard wiring it to you battery cleaner than plugging it into cigarette lighter/power plug, and pretty simple with a hard wire kit that replaces one of the “always on” fuses). The V200 circuit tester allowed me to find quickly find out which fuses had constant power from the battery and which fuses are only energized with the key to the on position. The tool provides auditory and visual indications, and the screen tells you exactly the voltage of the system – see picture. (You can also use the tool to check the voltage of the battery quite easily). I’m only at a DIY level but will likely be using this tool again to fix the wiring on my dad’s utility trailer. Besides testing circuits, the tool is also capable of diagnosing electrical shorts, open circuits, parasitic draw, etc etc. The tool has four modes Luckily, I don’t have to use any of the advanced functions yet but good to know that it’s there.The whole kit is pretty comprehensive and more than I need for my current project as VDiagtool offers simpler/cheaper kits, but I’d rather purchase a comprehensive kit and have additional capabilities in case I need them in the future.The Pro kit has several different connectors, a cigarette lighter adapter (can be powered by the battery or the cigarette lighter/power adapter) and has a 20-foot power cord to reach the front or the rear of your vehicle. The instruction manual is simple and straightforward (allowed me to use it to find always on fuses). However, the using advanced features are not explained in the manual...if you know how to use them I'm sure it is intuitive enough or seek youtube/internet for answers.The case is compact and efficient, you’ll have to carefully rewrap all components to get everything put back in to close the case. Good build quality and should last as long as you don’t throw it around/abuse it.The build quality of the testers is solid and does not feel cheap and flimsy. Audio, screen, and lights are clear and useful. The connections fit tightly together and won’t fall apart.BL – this tester exceeded my expectations and helped me save money with DIY projects.

This is a pretty nice tool used it to find a broke wire on a diesel fuel rail pressure sensor. Works great.
