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: Quality tester, accurate, with many features!! - When I was made aware of this tester, I wanted it yesterday. I ordered it on March 1st and it came on March 6th, which is really fast. Usually it takes 2 weeks to reach Hawaii. I have around 26 testers and just a handful is shown in one of these pictures. I still have my first tester which I made with a metal rod, light bulb, wire, and an alligator clip. These testers have sure come a long way since 1975 when I lst began working on cars. I have a Auto mechanics college degree and owned 170 cars since driving. Now days cars have a lot of electrical circuits and this tester is vital to have and own along with a good scanner, and a smoke detector for the EVAP system. I got this Vdiag Pro 200 tester and just by coincedence my neighbor's cars had starting and electrical issues. One I found a bad ground, one was a dying battery, one had a faulty starter, and my own truck had an exposed hot wire has you can see in one of the pictures. I was actually looking to see the tool in tight spaces like between the radiator support and grill when I saw this exposed wire. I tested it with this tool and it was hot. Using the tester I pushed the button and it lit up my auxillary fog lights. The tester fit well with my hand holding it inbetween the grill and radiator support.. The accuracy is really good as I have tripled checked it with other name brand testers you will recognize in the photos. I have a boat, riding mower, motorcycles, and 5 cars that I have tried this tester on. The quality of the tools is very good. The connectors are tight and the probing needle fits snugly. The fit is really good so while taking the wire from the front of the car to the back of the boat trailer, you can count on the connector holding and not coming apart like a extension cord usually does and you have to make a over under knott. Everything this company claims this tester can do is true. I even showed this to my mechanic friends and they were impressed. All of us use the P Probe and my P Probe III is in one of the photos. I have the P Probe from I to III and have no regrets. Now that I have this Vdiag Pro 200, it will be my go to tool. Before I had to carry a wire tracer seperately and was either the telephone one you see in the picture or my landscaping one for tracing sprinkler wires to trace my truck, car, and boat wiring. Now I have the best of both worlds in one easy to carry and store plastic case. I really have nothing bad to say. The screen is easy to see in bright sunlight, enough wire to reach from the front of the tow vehicle to the rear of the boat trailer. Built with quality materials, easy to use. The most important thing is it is highly accurate as you can see in one of the photos the other two tester I compared it with. Do not hesitate to buy this tester! Your life will be more enjoyable when working on electrical circuits especially if you work on cars, boats, motorcycles, your kids powerwheels, and even your home. Just make sure you turn off the power to your home when tracing your outlet to your fuse box. Not made to test live 120v or 240v AC home circuits. Only DC voltage from 12 to 24 volts DC. You will not be disappointed, I have been using this tester for a week now and it is accurate which is the most important feature for me and it is half the cost of other testers with more features. This tester is made for 12v DC to 24v DC so you can even test some of your power tool batteries that is within range.

### ⭐⭐⭐⭐⭐ Incredibly Multifunctional Electronic System Diagnostic Tool
*by S***K on April 12, 2024*

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.
