Review: AWESOME TOOL!!!!!! - 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.
Review: Awesome electrical diagnosis tool for a very reasonable price - 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

## Features

It supports ✔Tracing Wire ✔AC/DC Voltage Test ✔Diode, Resistance Test ✔Polarity Test ✔Continuity,Ground,Signal Circuit Test ✔Activate Components ✔Relay,Fuse,Trailer Light Test ✔Locate Short Circuits ✔Circuit Breaker Protection on all electrical systems of 12-24V vehicles.
- 【4 WORKING MODES】This auto power circuit probe tester supports 4 working modes: DC voltage (0.1V Resolution), AC voltage(for reading Max & Min Voltage, frequency & duty cycle easily), Resistance and Diode. It can tell you instantly whether the wire or circuit is live and which side of the circuit you are on, positive or negative. The unique tone On/Off Design allows you to judge the circuit voltage according to the volume of the sound in bright areas, which is intuitive & useful for working.
- 【COMPONENT ACTIVATION】V200 automotive circuit tester will help you accurately judge whether the component is intact. The component activation feature is designed to generate activation signals to the tested components, such as car lights, motors, windshield wipers, radiator fans, relays, fuel injectors, and other on/off-board electric equipment to troubleshoot electrical problems. With this electrical tester, you can activate components in your hand/vehicle/ with ground, etc.
- 【IDENTIFY POLARITY QUICKLY】 VDIAGTOOL automotive probe tester makes it easy to check component continuity and identify positive, negative & open circuits. If the probe tip connects to the positive terminal, the RED LED lights on with beep sounds; If the probe tip connects to the negative terminal, the Green LED lights on with a low tone. Neither LED Lights up when it is an open circuit. You can also use this circuit tester to locate short circuits in your car if you keep getting blown fuses.
- 【CONTINUITY, SENSOR/SIGNAL CIRCUIT TEST】With the press of a switch, you'll have an instant hot lead or ground lead. Using the alternating voltage mode of the automotive electrical tool, you can check the state of sensors, do continuity tests, judge the the connectivity of circuit via the transmitted signal and check the resistance of various sensors and issues, checking for the good and bad grounds. V200 will be an essential electrical tester for tracking circuits and identifying broken parts.
- 【OVERLOAD PROTECTION】V200 power circuit probe kit has a built-in 8-amp circuit breaker for short circuit protection. Whenever it is overloaded, it just gonna shuts down and restarts, which is a safe measure to protect the device and your components from overload. Additionally, this automotive electrical tool is powered by the vehicle’s battery or cigarette lighter, ✔NO extra battery is needed.

### ⭐⭐⭐⭐⭐ Impressed by Performance
*by C***K on May 3, 2024*

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.
