Review: Very Nice Bit of Kit well worth the price - Packaging The tester came in a cardboard outer sleeve. Once removed you will find a hard-plastic case that holds the tester unit and the accessories. Upon opening the box you notice how well the unit is fitted in there with a nice thick foam insert in the lid. First Look Looking at the unit you see how well it looks and some of the nice design features it has with the colour 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 colour 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 few headlight bulbs I had lying around not knowing if they were out or not. I connected the Aux cable from the probe to the negative on the bulb and touched the tip to the positive, this allowed me to check the circuit. The screen went green confirming no issues with the continuity of the bulb I then pushed forward on the toggle switch and applied voltage to the bulb lighting it up. A quick two-minute task is completed with the tester saving a lot of time and effort. My Thoughts, All in all a solid bit of kit with easy to use features and a easy to use menu. A Good design aesthetic and all stored in hard plastic case. a must for anyone who works on electrical systems.
Review: Should have bought one of these years ago. - Love this tool! Really speeds up diagnosis.. love the fact that you can inject positive or negative feed down a wire by pressing a switch.. makes circuit detection instant! works on 12 or 24v so good on cars/vans and commercial HGV also. Nice set of adaptors, well made and sturdy.. dont wait, just buy it.. will pay for itself in saved hours probably on the first job or 2!

- 🥇【4 Modes Easy-to-Operate Diagnostic】The circuit probe kit’s 4 modes can be accessed by simply depressing the Mode Button. ➊DC voltage: read the DC voltage with a resolution of 0.1 volts. ➋AC voltage: read the Max. voltage, the Min. voltage, frequency, and duty cycle. ➌Resistance: read the resistance between the tip and auxiliary ground lead. ➍Tone On/Off: technicians use the tone in a dark environment to distinguish the test results and turn it off when unnecessary.
- 🥇【Compnent Activation & Test】This automotive power circuit tester lets you activate and test on-board and off-board components with ease. It supports a wide range of vehicle systems, including blower motors, power window motors, windshield wipers, rear window defrosters, lights, radiator fans, and fuel injectors. By sending the required signal to each component, you can quickly determine whether it is functioning properly. Designed for both professional technicians and DIY enthusiasts, the tool works hand-held, in-vehicle, or with grounded connections, providing fast, accurate diagnostics and making electrical troubleshooting simple and reliable.
- 🥇【Instany Identify Polarity】Autel Car Circuit Tester instantly checks component continuity and quick identifies positive, negative and open circuits. When the positive terminal is connected, red LED lights up with beep sounds. When the negative terminal is connected, green LED light up with a low tone. If an open circuit, neither of LED light will not light. The indicator light is a considerate working guide to facilitate the smooth operation of detection.
- 🥇【Continuity Test, Signal Circuit Test】KZYEE Electrical System Probe Tester can test the state of sensors, quickly and accurately judge the connectivity of circuit via transmit signal, performing continuity test. Two ways to test continuity: ✅1: In resistance mode, if the resistance is 0.0Ω and the LED lights up, it means continuity. ✅2: Power up the connection using the power switch, if the circuit breaker trips, that means the resistance is low and there is continuity.
- 🥇【20FT Extension Cable, Built-in Flashlight】Kzyee automotive electrical tester comes with extra 20ft extension cable in addition to its own 20ft cable, allowing you to access any position of the vehicle and test it. Ideal for trailer wiring, it can be tested along the vehicle without having to find a suitable ground point. The built-in flashlight is convenient for detection, even in the dark or dim environment, it can provide the best view for who need to work in night.

### ⭐⭐⭐⭐ decent cheap tool
*by C***S on 27 May 2021*

As an Automotive professional brought this to replace my original power probe, thought it would be useful to display the different voltage on vehicles as opposed to just + & - V. Used everyday for last 2 weeks on approx 10 jobs per day and has performed fine, has 2 LED's that come on as soon as powered up that at first I found annoying but have to admit are quite useful, easy to probe into looms (beeps let you know when contact made). Only point I would make is having been a tech for many years tool does feel a bit cheap and lightweight, as opposed to just chucking this back in toolbox when finished I keep it out of the box on the dashboard of my van, and so far all ok I wouldn't think it would last long rolling about with other tools in a drawer, on the positive side leads are good quality and with the extension cable you could easily walk around an artic cab and trailer.
