I found this to be a very helpful tool to sort out problems with wiring. This made finding a broken wire in a harness much faster and easier than with a multimeter, loose wires and alligator clips. I first used it to find a break in a wiring harness on a motorcycle which you can see in my video. I found the break in less than a minute with the tester and without pulling everything apart. When using the probe the screen turns green showing you're touching a ground. A hot wire turns it red and shows the voltage. It also has a handy feature which allows you to momentarily put voltage to the tip of the tester or ground it to check the wiring or the device. This could be really handy if you're checking trailer lights. And with the 2- 20' cables, it give you a lot of distance to reach a long distance. The led lights on the tool are nice when you're trying to see in dark spaces without having a flashlight. It will do voltage tests for AC/DC, polarity, continuity and diode tests. But for me the most useful is for finding broken wires or checking continuity over a long distance. I've spent a lot of time in the past trying to track down a broken internal wire on a harness and this will make short work of it. It takes power off the vehicle battery using alligator clips provided or the cigarette lighter plug from the kit. It has a built in breaker which resets after about 15 seconds, so if you accidentally hit the wrong polarity you won't damage the tool. But you do need to be careful if you use the probe to push power to a device. You would want to be careful around automotive computers with the probe and pushing and voltage. I even used it for an application it wasn't really designed for. I needed to trace some wires in my house walls and ceiling. Using a 12 volt power pack I was able to trace both ends of the wires for a continuity check using the V200 tester. Of course I had the breaker shut off and the wires were disconnected from their terminals before I tested. I was able to figure out which wires went where in minutes. Much quicker and easier than what I would have done in the past. It would be nice if it could be used for higher AC voltages. But overall I found it quite helpful for sorting out DC wiring on vehicles. And it can also be used for low AC voltage checks which would be helpful with automotive applications. I'm quite please with this tool and I'm sure I have friends that will want to borrow it or buy one for themselves!

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.

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.

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.

If you have an automotive wiring problem this tool can help you diagnose the issue. I like that this meter has a graphic display of AC waveforms for testing PWM circuits or injectors. The meter will also allow you to measure DC voltage, Ohms and even test diodes. There is a second tool for tracing wires that is very helpful as well, especially since most automotive wires are covered in protective sleeves or wrapping and it is difficult to know where your wiring is going without unwrapping everything. There is an extension cord included if you are working on something with long wires such as trailer lights or maybe an RV. This tool costs less than an hour of shop time so if you are handy and understand basic electronics you can save yourself some money and use this tool to find any wiring issues you may have. I really like that it all comes in a small case so it is easier to keep all the pieces together. Note this tool is designed for automotive use and can NOT be used for household 120VAC or 230 VAC.

The V200 Pro comes well packaged with a carrying case and arrived undamaged from Amazon. I like that the V200 comes with both battery connector cable clamps and a 12v source connector. The extra 20 feet (40' total) of cable extension ensures that you can reach those longer testing runs. Another plus is the head light for use in low light/dark places or under dash testing. My first use of the tester was for verifying a 12-volt relay solenoid before installing (see pictures). Today I was using the unit to diagnose my work trailer wiring (see pictures). I really like that the tester can supply voltage to the wiring to verify the bulbs as they would not light connected to my vehicle. After removing the bulbs, I was able to verify they were both blown using the tester. I also verified I needed to clean my grounds. The tester helped make the day successful. The color LCD screen verifies DC ground (green) and voltage (red). The tester will also test diodes & AC circuits (automotive low voltage only) but I did not have any diodes or AC circuits to test at this time. I did verify the tester voltage against my Fluke meter, and it was within a tenth of a volt. If there are any faults with the tester it is with the description. My initial thought was that it would find AC circuit breakers from the AC outlet to the breaker box, maybe a dual use tool. But that is not the case. It is for finding a broken wire in a 12/24-volt DC circuit but not to locate short to ground. I did try it on my trailer wiring, but I did not get the results I thought I might get, so further use is needed to confirm. It did work well on a single test wire, and I got the results I was looking for. Excellent tester for the price. Disappointed in Amazon review posting: tried several times to post review but after a week still not posting.

Works about as well as my Powerprobe, but the buzzer function on this guy is strange as it doesn't give you the long beep when you are on battery voltage, it kinda just lets out a quick garbled chirp. This is a great tool for the home mechanic though and it is priced very reasonably you just need to pay attention to the screen and not the sound which can be aggravating in some situations or mine just came defective.
