    Handy tool for electrical work

    5 months ago
    [This review was collected as part of a promotion.] I’ve been using the Innova 5420 PowerCheck Circuit Tester for a few months, and it’s become one of my go-to tools for troubleshooting electrical issues. The setup is very straightforward—just clip it to the battery, and you’re ready to test circuits, relays, fuses, and switches without any hassle. What I really like is the ability to supply both power and ground directly through the tester. This has saved me a ton of time when checking things like fans, pumps, and lighting circuits. Instead of swapping parts or guessing, I can instantly verify whether a component is good or if the wiring is the issue. The display is clear and accurate, showing live voltage readings which helps a lot when tracking down intermittent problems. The build quality feels solid and durable, and the probe is long enough to reach tight spots under the hood. It works perfectly across a wide range (6V–24V), so I’ve used it on both passenger cars and heavier trucks with no issues. Overall, this is an excellent tool for DIY mechanics and professionals alike. It speeds up electrical diagnostics and gives you confidence before replacing any part. Highly recommended if you want to save time and avoid guesswork when dealing with electrical systems.

    [This review was collected as part of a promotion.] My go to tool when im diagnosing electrical issues. This allows me to test the function of a part on the electrical to know down the issues. The tool is solid and very well made. I like the option of being able to adjust the angle of the head helping to get in harder areas.

    Great product

    [This review was collected as part of a promotion.] The long, flexible probe allows easy access to hard to reach areas, and the ergonomic handle ensures a comfortable grip during prolonged use. The LED indicator lights and audible tone provide clear and immediate feedback, making it a breeze to identify power, ground, and open circuits. What sets this circuit tester apart is its automotive power source compatibility. Simply plug it into your car's power outlet, and you're ready to troubleshoot electrical issues without relying on external batteries. This feature not only saves money on disposable batteries but also ensures the tester is always ready for use.

    Easy to use, very helpful in performing diagnostic

    5 months ago
    [This review was collected as part of a promotion.] The Innova 5420 power circuit tester has been very useful for diagnosing electrical issues in my vehicles. I like that this power probe can send 3V or 5V, in addition to 12V, compared to others I have used in the past. In addition, the pivoting head helps get to hard to reach areas. The long cord has been very helpful as well. It allows you to connect directly to the car battery, or via a 12V outlet. The unit has been durable so far, and I have had many Innova products for several years now. Although power probes have a learning curve for beginners, they are very helpful in automotive diagnostics. This unit has an easy to use interface, and the backlit display is nice. Most importantly, this can help save time while performing diagnostics. I recommend using this power probe in addition to a multimeter.
