100% Brand New

This is a compact yet powerful diagnostic tool designed for 12V-24V vehicles (3.5V-36V systems). With four advanced testing modes—DC voltage, polarity detection, continuity, and ground testing—it enables rapid and accurate fault diagnosis, making it an essential tool for both professionals and automotive enthusiasts.

Designed for simplicity, just clip the device to the car battery, and you're ready to diagnose. The powerful probe tip and ground lead allow you to instantly activate or test components like radiator fans, starter motors, relays, and more—all without blowing fuses or wasting time.

Stay informed with the blue LCD voltage display and built-in LED illumination, ensuring visibility even in low-light conditions. With overload protection and an audible beep warning, the kit prioritizes safety, giving you confidence during diagnostics.

Quickly identify polarity without pressing a button. The surface probe instantly detects whether a circuit is live, with a red LED indicating positive polarity and a green LED for negative, streamlining the diagnostic process.

Equipped with a 14.6-foot extension cord, it offers unmatched mobility, allowing you to test circuits throughout an entire vehicle with ease. Perfect for cars, trucks, and more, it eliminates the struggle of finding a suitable ground point.

Whether you're a seasoned professional or a DIY enthusiast, this device delivers precision, speed, and reliability, making vehicle diagnostics easier than ever.

For the best performance, begin by connecting the device to a fully charged car battery. Use the probe tip and ground lead to test and activate components before installation, confirming their functionality in advance. When checking polarity, note that the red LED indicates positive polarity, while the green LED signifies negative polarity—providing instant feedback to prevent errors and save time. To maintain durability and keep all components organized, store the device in its protective case when not in use.
