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.

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.

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.
