VDIAGTOOL V200 Automotive Circuit Tester, Power Circuit Probe Tool, 12-24V Electrical Short Open Breaker Circuit Finder, AC/DC Current Resistance, Duty Cycle, & 20FT Extension Cord, for 99% Cars

The tester came in a cardboard outer case and carry handle. Once removed you will find a hard-plastic case that holds the tester unit and the accessories. First Look Looking at the unit you see how well it looks and some of the nice design features it has with the color screen and the removable probe along with a massive 20ft extension cable. It has all the connections you need, Direct from the battery or from the included lighter socket adapter. First use The unit was powered by the lighter socket and booted up into the menu in a second. You are presented with a nice clear color display and 4 menu options at the top of the screen. The unit has 2 led's on the top of it giving you some light to work with. You select the menu option with the round menu button on the device. The menu runs through the following settings DC Voltage, AC Voltage, Resistance and Diode Just press the menu button until you see the correct screen. With the probe in DC Voltage it allows you to read the DC Voltage of a circuit The AC Voltage does the same but for AC Voltage The Resistance mode enables you to check the resistance between the tip and the Aux ground Lead. In this mode you can check the voltage drop from positive to negative on a diode I used the probe to check a polisher tool that was not working right and needs a new trigger switch . I connected the Aux cable from the probe to the negative on the white wire and touched the tip to the positive black, this allowed me to check the resistance for the variable switch. It told me the switch was bad and not changing the resistance. A quick two-minute task is completed with the tester saving a lot of time and effort. Great tool for checking for broke wires on any vehicle.

Overall it's simple to use its got your mode button and your rocker switch allowing you to either give something 12 volt power or if it's ground side controlled you can also power it that way screen brightness could be a little better it does come with both alligator clamps or an auxiliary cord to power from your cars auxiliary port in your cab it also comes with a very long extension cord which you easily move around your whole car no trouble at all although it's not as durable feeling or logistically enclined as your few hundred dollar power probe for the 60 bucks your going to pay your definitely able to check for continuity find bad or open grounds power any of your electronically controlled parts of your car overall a great buy

I've been fooling around with this for several weeks now. I have a '68 GTO that I have had for 25 years that is in a total restoration. The first thing I wanted to test was it's accuracy. I tested my battery and got a reading of 12.4 volts which matches what my voltmeter says. I am having problems with the horn so I tested the relay and found it to be hot so that told me the problem was in the steering wheel. I was also able to verify that my windshield wiper motor was dead and it wasn't a problem in the wiring leading up to it. What I like is that you can hook it up to the battery and the cord is long enough to reach around, comfortably, to the tail lamps to work on them. I admit to being a novice at using one of these and it showed when I pressed power on the V200 while on a hot wire. This tripped the circuit breaker in the V200 so nothing was damaged. For the price this is a good product.

Very helpful tool. May be a bit simplistic for some but surely nice to have for we DIYers. A multimeter may do the same thing in many situations but what setting and?... Helped me track down a short. Now, if it just gave suggestions of how to fix or bypass it! I just hope it lasts. One negative. That probe end is sharp enough but it still can not get into the mini fuse holes to make contact. Had to make a jumper.

My '98 Jeep Wrangler would crank, but not start. I wasted time, labor and money replacing parts to no success. Changed strategy. OBD-II scanners wouldn't connect w/ the PCM (computer brain) and it became my main suspect. PCM problems are difficult to diagnose because it's the components whose job it is to tell you that there's a problem, and if it's dead, well, you have another problem. I hesitated to spend more money on a PCM without being sure, so I bought my first "Power probe" to test the electrical system. After hours of poking away at wires and components, I was finally able to reasonably diagnose that my PCM was dead and ordered a replacement. New PCM installed, Jeep started right up and is running great. This was my first time using this kind of tool and it saved me the necessity of towing my dead Jeep to a shop to spend even more money having a pro diagnose my problem. I feel empowered. The VDiagtool probe is a great addition to my tool box.

I have used this tool now for about 6 months, multiple times, and has saved me time and in my line of work time is actually money. I have also had the experience of having to go through the warranty process and it was smooth, a few emails and some pictures later it was replaced. The sent me an all new kit even and that was not expected as it was the probe that failed(just wouldn’t turn on one day). So far my experience with this tool is all positive and I believe that the CS is top notch right now. So in conclusion I would 100% recommend this product to anyone interested in a Power Prob brand one consider this instead.

Used tool

This is my first time using a tool like this. Been using it for the past month now on several vehicles. Checks voltage/amperage like a multi meter but can also apply power to actuate components that need battery power. Great for troubleshooting. A tool that saves a lot of time. Ive been able to trouble shoot faulty fuel pumps, window motors, power seats and door locks. However i dont think it can be used on high amperage circuits like a starter. I havent tried powering a starter but dont think it was designed to apply high current. Wish I had this tool when I worked at a shop. No longer work at a shop but still work on a lot of friends and family vehicles. Highly recommended.

First job I used it on was to test in-tank fuel pumps - worked a treat and established pumps were unserviceable - great bit of kit!

Amazing unit, have used it for about a year now, zero issues

Not working. Blank screen

All worked good. Only issue I would say have to be mindful when connected the cables when use the extension cable.
