Review: An excellent tool for diagnosing electical issues at a great price! - This probe will allow you to easily test automobile, RV, boat, and trailer wiring. It is packed with features that allow the probe to test voltage, resistance, and perform signal tracing. You will be able to energize electical parts like lamps and relays with the probe. The tool comes packed in a nice padded case that holds the probe, probe tip, breaker test probe, cigarette lighter adapter, a 20 foot extension cable, and battery terminal clamps. I first learned to operate the tool by performing some simple tests. Connecting the probe to the vehicle's power source is easy. You can connect right at the battery using the included clamps or with the lighter plug. By placing the the probe into Mode I, it can measure the battery voltage by pressing the rocker switch forward where the digital display will then display the positive voltage. Pressing the red button will scroll through the tool's feature set - DC voltage, AC voltage/frequency, resistance, and diode testing. I measured the resistance of my old VW's ignition coil with the probe (you can see the measurement in one of my photos). This is a useful feature for measuring resitance of relay coils, carb thermostats, and idle solenoids. When you push the rocker switch forward, the probe tip is connected to positive battery voltage. You can use this feature to power and test bulbs, relays, and solenoids before you install them into the vehicle (or check them while they are in place). The probe tip can pierce wiring insulation to allow testing without disconnecting wires. I especially appreciated the inclusion of a 20 foot power extension cable that will allow you to move the probe to far reaches of the vehicle. There is no need to make power connections at another part of the vehicle. There is a signal tracing feature when the tool is placed into Mode II. This will allow a signal from the probe to be placed onto a wire and you can then use the breaker probe to move along the suspected wire. A tone is heard from the tester as you move along the wire and will cease when you reach the breakpoint. I used this feature to finally locate the reason the rear lift gate on my Ford Escape would not raise with the foot activation. I found a break in the sensor wire right as it entered a multi-wire connector. I was able to solder a wire around the connector to get the liftgate to work once again. The probe paid for itself on just that one job. A dealership repair would have cost hundreds of dollars. The instruction manual is a bit hard to understand, but there are several excellent Youtube videos that review this tool and show how it can be used. If you compare this tool to the PowerProbe 3 or 4, you will see it works very similar but at a much reduced price. I really like this tool and look forward to finding other uses for it.
Review: Must-Have Circuit Tester for Any DIYer or Mechanic - I recently bought this circuit tester and it’s been worth every cent. The tool — especially the breaker finder — helped me track down an electrical issue I was still having even after replacing my battery. The problem turned out to be a broken connector going to a sensor, and the breaker finder made it super easy to pinpoint. It was also great for checking fuses and connections on my Ford Maverick Hybrid while I was doing repairs. The whole setup is very user-friendly and feels well-built: long cables, solid connections, and an instruction manual that actually helps the average DIYer. Overall, this is a great tool for anyone in the automotive world — DIY or professional. Highly recommended.

### ⭐⭐⭐⭐⭐ 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.
