VDIAGTOOL V200 PRO Upgrade Kit Automotive Power Circuit Probe Tester with 30PCS Back Probe,12/24V Car Electric Open Short Circuit Break Finder,AC/DC Voltage Component Relay Fuse Test 40Ft Cable Tracer

Cracking tool paid for itself already Many uses would recommend

Had a fault with my tool, the level of customer service they provided was second to none. They were very responsive and sent me a replacement with no hassle. The too is great does everything you need it to. Would definitely recommend

I have always wanted a power probe style tool but didn't want to pay the price for the name brand. So I took a shot on this one. It works fabulously! I found the back probe set incredibly useful in hard wiring my radar detector to my vehicle. It made the job so much easier (and safer) than trying to use standard leads or cutting into harness wire insulation to identify switched power. I was able to confirm ground, power, and switched power all without any risk to my vehicle or radar detector and without disturbing anything. Think of this tool as a hand and time saver. So many times a project requires a helper to hold or do something. With this thing you can inject power OR GROUND directly from the tool's probe - and that saves immense time. Also, it comes with LONG power leads (and an additional 20 foot extension too!) and so I will definitely be using this tool soon to figure out my boat trailer lights, which never all seem to be working at the same time. I'll simply inject power or ground directly at the trailer light assembly to quickly see which lead is bad. Finally, the circuit break detector was VERY helpful in identifying WHERE in a harness a single wire had broken on a expensive coil assembly. This breaker finder saved me from having to tear off the entire harness to find the wire break. If you can swing the extra money, I REALLY recommend the "pro" kit with the added probes - it just makes life easy and safer. About my only complaint is the clear rubber covers for the (very sharp) needle probes don't have a retainer. Be careful where you put them as they'll get lost easily once taken off the needle tip during use. Otherwise this kit is outstanding.

This is my first circuit tester, and I’m absolutely amazed by what it can do! Right out of the box, I was impressed with the packaging—it was neatly packed with foam inside the case to prevent any movement or damage during shipping. One of the first things I noticed was that it comes with a variety of test leads, which adds a lot of versatility. It hooks up easily to a car battery or cigarette lighter outlet for power, and it even includes an extra extension, which is a great bonus. Using this tool, I was able to test the voltage on any wire I poked, giving me instant and accurate readings. I also checked the voltage levels on different wires, and it helped me pinpoint where open shorts were located. Honestly, I have no idea why I didn’t get one of these sooner—it would have saved me so much time on past projects! Additionally, I tested fuses, and it provided clear voltage readings, making troubleshooting even easier. Another standout feature is the breaker finder tool. It works surprisingly well—just turn it on, and it emits a static noise to help locate breaks quickly. This makes diagnosing electrical issues much more efficient. So far, VDIAGTOOL has been great to me. I already own one of their scanners, and now this circuit tester has exceeded my expectations as well. Their products seem to be of really high quality, and I haven’t had any issues so far, which is a huge plus. If you’re on the fence about getting one, I highly recommend it!

These are one of the best tools I’ve ever used. I used it to check if there was any wiring problems in my minivan. It helped me detect the exact location of trouble on wire . It came with so many accessories. I can use it for so much - checking voltage, electricity, battery levels component amper , wiring issues, and much more. It comes with so many different plug types. The wiring is also long . The best part is that it even comes with an extension cord. It even has LED lights at the end, which saved me from using my own flashlight. So convenient.

I tested the VDIAGTOOL V200 PRO tool tracing out wiring issues on a couple different utility trailers and a pickup truck with a short. Now I had other ways to test the wiring but this tool made it so much easier. I love the fact that the extension cable allows you to reach a long way. It has multiple ways to get power to the tool for testing lights, putting power on wiring with the push of a button. The breaker finder worked fine once I replaced to battery it came with. The included battery was dead. I have several breaker finders for 110 volts. This works as good as them up to 24 volts but using one is something you have to master the art of. I know people complain when things don't come with batteries but I prefer they don't so I can buy good quality ones. The accessories are a big plus just wished they had included a better bag or plastic box to keep them in. I bought my own plastic box, a soap bar holder to be exact as they are cheap and I use them for a lot of smaller items. Now most people who would buy these types of tools generally know how to use them. I tested this in a few different ways like when it got hot sitting in my truck and putting it in cold conditions. Yes, there are important to me as many times I carry a few tools and forget to take them out. The plastic accessories held up well in both temperature differences. The quality of this tool is very good in my opinion and is well worth the money you spend. The accuracy of the voltage readings were fine and verified with other voltage meters.

I like the accessories for testing small connectors which is why I purchased it. 4 stars because the plastic case is cheap and too small.
