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 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.

The media could not be loaded. I enjoy working on my old cars and motorcycles, so I decided to try the V200 Pro because it includes a broken circuit wire tracing system. This feature caught my attention when I purchased an older Chevy Tracker and noticed the low oil pressure light on the dash wasn’t working. Upon inspection, I discovered the wire to the oil pressure sensor was completely missing—there wasn’t even evidence of where it had been cut or broken. I searched everywhere, including underneath the vehicle, but couldn’t locate it.Before buying the V200 Pro, I watched several YouTube reviews of the V200 model. While some reviewers did a great job explaining how the "Circuit Breaker Finder" worked, others were less helpful. One reviewer even made the absurd claim that the device could trace electrical power in wires without connecting the red signal wire, which is essential for the system to function. This taught me to take YouTube reviews with a grain of salt—not everyone reviewing automotive tools is knowledgeable. However, based on a few detailed reviews from reliable sources and Amazon's good return policy, I decided to give the V200 Pro a shot.I also tried to find wiring schematics for the Tracker online, but the information was limited. Thankfully, I found the color code for the wire I needed. Using the back-probe included in the upgraded V200 Pro kit, I connected at the first connector after the fuse. I had been searching for the wire’s path through the engine compartment to reconnect it to the sensor. In the past, I’d bought a wire tracing device that was a complete waste of time and money, so my expectations were low.To my surprise, the V200 Pro worked perfectly. It identified the wire’s location and even pinpointed where it had broken within a wrapped bundle of wires. Without this tool, I doubt I could have found the problem. I was so impressed that I recorded a short video to show a friend how effective it was, which I’ve included with this review. I’m thrilled with the V200 Pro and wish I’d purchased it sooner.Since then, I’ve used the probe function on the V200 Pro multiple times. It’s incredibly handy for checking fuses and relays. For example, a neighbor called me for help with her 1956 T-Bird after she burned up an old wire while replacing the coil. She’d tried using a multimeter but wired it incorrectly. I showed her how easy it is to check polarity with the V200, and she had her wiring fixed in minutes.The V200 Pro is a reliable, user-friendly tool and has been a great addition to my automotive toolkit. I highly recommend it to anyone who works on vehicles!

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.

I bought this to do some automotive electrical work on some older vehicles. So far it’s been great. Still trying to learn some of its capabilities.Overall happy with the amount of functions this tool offers.Would definitely recommend to anyone working on automotive electrical components.
