Review: Pleasantly suprised on how well it works - Good things DO come in small packages. I purchased the Vdiagtool V200 kit to see how it compares to my expensive Powerprobe kit that I have in my toolbox at work. It basically does the exact same things for a fraction of the cost. First it comes in a small plastic case to house the leads as well as the probe and the signal sniffer. It’s a little tight for someone who just wants to throw it all in there, but you SHOULD be nice to your tools and wrap them up correctly and put them away correctly and they should last a LONG time. Using the probe was very easy. Attach the leads with the alligator clips to the probe lead, red to positive of the battery and black to a good ground (or you have the option of a 12v cig lighter plug). There are 2 – 3way rocker switches. One on the lead and one on the probe. The one on the lead is your main selector switch. Forward is for the probe and reverse is for the signal generator. The probe also has a round button in the center to select even more modes. AC Voltage, OHMS, and Diode/Continuity. I was pleasantly surprised to accidently come across this because I ALWAYS use a continuity test and most newer meters these days have them but they don’t have an alarm to notify you like this does. Otherwise it offers 12 tests you can preform: Diode Test (Reverse only), Polarity Test/Check, Continuity (my favorite), resistance (ohms), short check, ground test (good or partial ground), AC & DC Voltage, Voltage Injector, Signal Injector, Open circuit tester and Signal tracer. You have 2 VERY bright led lights in front that light up when you are using the main probe to “inject” a 12v power or ground to trouble shoot. These are done using the probes 3 way switch. Forward sends 12v (battery voltage to be fair, it isn’t regulated voltage) and depressing the switch down sends a ground signal. Also when you do this the display changes color to let you also know what mode you are in. RED for power and GREEN for ground. You would use this option say to test a window or door lock switch (be sure it’s a 12v switch and not a DATA run switch though first) or to test the window motor or lock actuator. Or in my case I ran aux backup lights on my truck and forgot which one of the dozen wires I ran is for that, Went wire by wire injecting voltage until the light lit up. Saved me from tracing the wire. With this kit I COULD HAVE traced it easily (minus crawling under a rusty truck) The signal is generated within the main probe using a 1.2Khz square wave for a digital signal. This is introduced by rocking the 3 way on the lead towards you, then you use the small alligator clips to hook up to the wire you want the signal to run through. Once you do that, you turn on the signal “sniffer” probe (battery was INCLUDED!) and verify you have signal by listening to the tone and then just follow the wire either by itself of in the loom. If the signal goes away before the device it is powering then you have an open (break in the wire) or a short in the wire and this will show you (via tone) exactly where that is IF that is what you are looking for. Overall I am happy with this. The larger kit offered obviously comes with more adapters and bells and whistles but for the average DIY Joe this is perfect. Does it replace a DMM? Well yes and no. it all depends on what you need it for. But for troubleshooting this is a MUST. It is roughly 20 feet over all in length which is good for MOST cars and trucks on the road today. I am sure they offer extensions which would be really handy to work on trailers because those wires always go BAD!
Review: Incredibly Multifunctional Electronic System Diagnostic Tool - As a DIY mechanic, this tool was an amazing upgrade to the digital volt meter (DVM) I have used over the years to diagnose electrical problems. While VDIAGTOOL V200 Pro incorporates many functions of a DVM, the first thing is you never have to worry about dead or corroded batteries as it uses the power source from the vehicle it is diagnosing. In moving from a DVM to the V200 Pro, it requires some additional instruction and precautions to eliminate damage to circuits you're testing. For instance, unlike a DVM, the V200 Pro has the capability to power a circuit in order to check relays, bulbs, fuses, etc and you need to understand wiring schematics and characteristics before applying voltage to modern car circuitry. There is a nice concise manual included with the V200 Pro that gets things started and there are multiple online videos that can teach you more on the real-world operation of the tool. There are competitors in the marketplace and while many of their features are similar, the VDIAGTOOL V200 Pro is an unbeatable value for its price. Some of the other things it is capable of doing is testing relays, fuses, resistors, ohms, continuity, and something that is very helpful is the "circuit breaker finder" that is included in the kit. To note; the circuit probe runs off the vehicle's battery/power, the circuit breaker finder is shipped with and requires one, long-lasting 9V battery. While I have not had any broken circuits to repair since I purchased the V200 Pro, I tested the circuit breaker finder and found it to be quite helpful finding a circuit within a wiring loom. My test was on the headlight of my 2014 Jeep Grand Cherokee and I used the circuit breaker finder to track the wiring from the fuse box all the way to the headlight. This was beneficial as the main wiring loom breaks down into several smaller looms around and behind parts and structural pieces. The circuit breaker finder made it easy to trace all the way to the headlight. There is a volume control on the circuit breaker finder to help squelch "noise" from competing sources. The VDIAGTOOL V200 Pro comes with an approximately 16' long cable that easily reaches most vehicle's battery, and if you're servicing a big RV or trailer of any kind, it comes with an extension that is about 16' feet in length that should take of 99% of diagnostic situations you'll find yourself with. In addition to alligator type clips for the battery, there is a cigarette lighter plug that can be used for power as well which add to your accessibility. Overall, the VDIAGTOOL V200 Pro is a very capable electrical diagnostic tool and is rated for systems ranging from 12V to 24V. Each time I use the tool, I continue to learn more about it and with it's capable of. Having the VDIAGTOOL V200 Pro in your toolbox will set you up with the equipment and technology to handle most vehicle electrical challenges you might face.

### ⭐⭐⭐⭐⭐ How did I do without this tool for so long? This is a game changer!
*by W***. on March 10, 2024*

I am a serious DIY automotive enthusiast. I am also an electronics engineer. I purchased the Vdiagtool V200 Pro to assist me with a vexing electrical problem. I bought the V200 Pro after watching a YouTube video and anxiously awaited receiving it. I was impressed with the obvious build quality. The wires are well insulated and flexible. It feels great in the hand. I have a 2010 Ford F150 with a 5.4L V8. I had it parked in my back yard and rodents got into the engine compartment and chewed up some of the wiring. It also had a problem with the AC clutch compressor being inoperable. The engine ran poorly with multiple misses and engine light came on and could not be reset. I used a code scanner to determine three of the injectors were not working. The wiring goes from the injector into a harness that disappears into a loom. I placed the V200 into AC mode and started the car. I then went to the injector connector and touched the terminals of the injector…. nothing. I then used a small terminal to connect the red wire of the probe to the injector and set it to signal trace mode. I grounded the black wire. I then ran the signal tracer over the wiring harness while listening to the “warble.” It took less than 60 seconds to trace the harness to the point where the signal stopped. It was buried inside a complicated and loaded harness. Closer inspection showed there were visual indications of the wire chewed in two pieces on the bottom of the harness by those pesky rats. I would have had great difficulty finding it with another method. I was able to repair the harness by cutting the loom and soldering the wires back together. I then found two other wires the same way. The engine was now running great! No misfires and the injectors all working! I then began to play with the V200 in its normal voltage measuring function. The engine was running and I noticed that the voltage of the battery was 12.2 VDC instead of the expected 14.4 volts. Those pesky rats were at it again. With the help of the V200 I quickly located the wire to the field terminal of the alternator. It was chewed at the connector. A quick repair and all is well. Having such a good day I decided to look at the nonfunctional AC compressor. I pulled the AC relay under the hood. Using the V200, I probed the coil terminal and determined it was not being actuated when the AC was turned on. I then moved to the relay output and used the V200 to simulate the relay operation by injecting battery voltage into the output terminal. The compressor clutch immediately engaged. The problem was evident. The compressor was prevented from operating because it was so low on refrigerant that the low-pressure sensor prevented it from turning on. In this vehicle, you cannot add refrigerant without the compressor running. I used the V200 to activate the compressor, and I added R134. In a couple of minutes, I was ready to go and was able to replace the relay, which then operated on its own. The bottom line is that I very much like the V200 Pro. It is a great tool. Well made and very versatile. It made a tedious task easy and saved me much time and effort. It is a well-made tool and has earned a top spot in my toolbox. It will easily perform almost any electrical diagnostics on an automobile. It will not replace my Fluke multimeter for critical measurements, but that is not its purpose. This makes troubleshooting wiring for almost any automotive circuit. Taillights to wipers, blowers to power windows, relays to seat controls. This is now my go-to favorite! I have oscilloscopes and meters of all types, but nothing works better for me when working on automotive wiring. I plan to buy another for my son for Christmas.
