Digital Automotive Fuse Current Tester – 12V/24V/48V Car Leakage Analyzer & Parasitic Drain Diagnostic Tool

Digital Automotive Fuse Current Tester – 12V/24V/48V Car Leakage Analyzer & Parasitic Drain Diagnostic Tool

​Product Description

​Stop guessing and start diagnosing. The CNBJ-611 is an essential diagnostic tool for identifying electrical faults and parasitic battery drains in seconds. Designed for both domestic and commercial vehicles, this tester plugs directly into your fuse box to provide real-time, high-precision current readings without the need for invasive wire cutting

​Whether you're tracking down a "mystery" battery drain or testing a specific circuit’s load, the CNBJ-611 provides the accuracy and safety you need in a rugged, workshop-ready package

​Key Features:

For big standard fuse or mini fuse use. Please check the picture for reference 

​High-Precision Diagnostics: Accurately measures current from 0.01A up to 19.99A with ±2% accuracy. Perfect for detecting even the smallest current fluctuations

​Plug-and-Play Simplicity: Just remove the fuse, insert it into the tester's socket, and plug the tester into the vehicle. It maintains circuit protection while you test

​Backlit LCD Display: A clear, high-contrast blue backlight ensures you can read data in direct sunlight or under a dark dashboard

​Integrated LED Flashlight: Features a built-in front-facing LED to light up cramped fuse boxes and dark engine bays

​Rugged Construction: Built from high-impact ABS material with a comfortable, non-slip grip designed to withstand daily use
