VDIAGTOOL V200 Power Circuit Probe, Automotive Circuit Tester Kit, 12V-24V Short/Open Circuit Breaker Finder, Component Activation, AC/DC Diode Resistance Relay Fuse Trailer Light Test, 40FT Cables

The VDIAGTOOL V200 tool works great. I particularly like the long cables and sharp probe. Its a great quick and easy alternative to pulling out the multimeter. The ability to send power helps test components super quickly, as you can see on my video. Great price for a great tool

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.

After a little less than 2 years of light use My V200 failed. Specifically the probe became electronically disconnected from the rest of the device (perhaps an internal fuse?). So why the 5 stars? Because after 2 years the Vdiagtool folks still took care of it. Sure they asked a few questions and requested a short video demonstrating the problem but they were always prompt and professional and there was never any hint that they were giving me the run around. The replacement was sent quickly and they didn't make me go to the trouble of returning the defective unit. Thanks!

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.

It burned out with only a few uses. I don’t recommend anyone buying this product. Buy at your own risk. No good at all. All my money down the drain.

Not sure how I lived without this. So many functions and capabilities.

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.
