Features

  • Short Circuit Finder for Continuity Testing - Have you ever faced issues like headlights not turning on, power windows malfunctioning, or the cigarette lighter not workingwith no idea what's causing it? This multifunctional automotive circuit tester helps you accurately diagnose common electrical faults such as short circuits, open circuits, bad grounding, and abnormal voltage. It quickly pinpoints the problem area without the need for repeated disassembly. You can also test whether parts are properly powered, saving time and effort during repairs.
  • Test Light- Equipped with a backlit high-definition LCD screen, it provides real-time and accurate voltage readings with a margin of error as low as 0.2Vmaking even small voltage fluctuations easy to detect. The built-in LED light allows for hassle-free testing in dark environments or tight spaces, so you're never limited by poor lighting.
  • Fuse & Voltage Tester - Even if you have zero experience with car repairs, you can get started quickly: Connect the red clip to the batterys positive terminal and the black clip to the negative. Once powered on, the voltage value will instantly appear. Simply touch the probe to a circuit point to check continuity, voltage status, and polarity. If an overload is detected, the buzzer will sound immediately to alert youhelping protect both your battery and the tester.
  • Multifunctional Car Circuit Tester Reach Anywhere in Your Vehicle - With a 14.7ft flexible extension cord, you can reach the front engine bay or rear trunk with easetest multiple areas without repositioning your battery connections.

Description

Easy-to-use and accurate car circuit tester efficiently checks electrical systems, continuity, circuit breakers, polarity, components, and voltage. Convenient for testing and repairing in a dark place. When the positive and negative poles are connected incorrectly, a warning sound will be emitted. Easily test voltages in the range of 3.5 V to 36 V and display the values on the screen The tester's probe checks the car's contact polarity without a key press: red LED for positive, green for negative. Press 'Up' to connect the probe to the positive '+' power supply; press 'Down' to connect the probe to the negative '-' power supply.

I should have bought this years ago. I absolutely love it. The ability to test for power and ground with a single touch is a hugh time saver. You also have the ability to press the rocker switch to send power or ground to a wire to test. Well built. Price wa good to making it even better. The cables are plenty long to go around most cars and trucks. ... show more

Literally the exact same functionality as the $200 power probe brand one minus the beeps, may even be able to use the power probe tips in it, but the tip it came with hasn’t broke to find out yet!

    • Budget alternative to a Power Probe
Color: Red
This tool is a $16 somewhat-clone of the Power Probe. You connect it to the vehicle's battery or other power source and it will tell you the voltage and allow you to connect the metal pin on the end of the probe to either power or ground. That allows you to feed system voltage into the circuit or connect a hot circuit to ground. There are a few more features (color-coded LEDs that indicate power or ground on the circuit being tested) but they're easy enough to figure out so I won't bore you with the details. Nothing in my garage is broken right now so I tested this with a spare car battery and a headlight. It works exactly as expected-- I could feed the headlight power if it was grounded, or I could connect it to ground if it was being fed power. Either would cause it to light up. Simple. The current limit on the probe is 8 amps so it will energize the control side of most power circuits, but it may overload on something like a fuel pump. It has some sort of overload protection (and a buzzer that sounds when the threshold is exceeded) but I'm not sure if it uses a fuse or a circuit breaker. I'll probably take it apart soon to find out. My preference would be a self-resetting circuit breaker, but no matter what it is I wouldn't count on it too much. 8 amps is still a fair amount of current and it will do some damage if connected to the wrong circuit, so be careful. Do you need this tool? Absolutely not. You can do everything that this tester does with an inexpensive voltmeter and a pair of jumper wires, which you should already have if you're doing any sort of electrical diagnosis on an automobile. And if you're a professional mechanic and you do a LOT of electrical testing, you might be better off spending the money for an actual Power Probe, which will most likely be more durable. Where this thing really shines is for people like me-- someone that can do more than just basic diagnosis but who cannot justify the almost-$300 price tag of a Power Probe. Instead of trying to mess with connecting and disconnecting jumpers, I can connect this thing to the car's battery and test power, ground, and individual components in seconds. This thing is FAST if you know what you're doing. If you're a serious DIYer or an apprentice technician and you have a good handle on when and how to use a test light and a voltmeter, this tool is perfect for you. It does a good job and at $16 it is a FANTASTIC bang for the buck. If you learn to use it, you'll save tons of time diagnosing power circuits and doing component tests. ... show more

    • It did what it was supposed to do
Color: Blue
I bought this to troubleshoot why the terra-select switch stopped working on a 2015 renegade. With this tool I was able to determine it was a bad ground and made a new ground and the switch works again. Now, will this have a long lifetime? I do not know the answer to that, but I do know that it has paid for itself already. ... show more
