Key benefits Fast, reliable checks of a vehicle’s electrical system so you can find problems before they cause breakdowns. Combines multiple test functions in one handheld tool to save time and avoid swapping meters or testers. Long reach and built-in light let you work comfortably in cramped or dark areas without additional tools. What it does Multifunctional circuit testing: checks electrical systems, continuity, polarity, grounding, and voltage detection in automotive applications. Clear LCD readout: bright blue digits display battery voltage and test results for easy reading. Built-in flashlight: illuminates work areas and doubles as an auxiliary light when the clips are connected to the battery terminals. 5 meter cable: extended reach allows testing from the battery to the dashboard or other remote points without moving the battery. How to use Connect the red clip to the positive terminal and the black clip to the negative terminal. The backlight and voltage reading activate automatically. Read the voltage and test indicators on the LCD screen to assess battery condition, grounding, polarity, or continuity. Compatibility and performance Designed for automotive use; suitable for car and light vehicle electrical systems. 5 m cable length provides access to dashboard, fuse boxes, and wiring harnesses from the battery location. Clear, immediate LCD values and polarity indicators help you diagnose faults quickly and with confidence. Practical applications Pre-start battery check: confirm battery voltage and polarity before starting the vehicle or before jump-starting to avoid damage to electronics. Dashboard and accessory troubleshooting: reach from the battery to the dash to verify voltage at fuses, switches, and connectors without disassembly. Grounding and continuity checks during installations: verify proper grounding and wiring continuity when installing stereos, alarms, lights, or other aftermarket accessories. What makes it useful Consolidates multiple electrical tests into one compact tool, reducing the need for extra meters. Long cable and built-in light improve access and visibility in tight engine bays and under-dash areas. Simple clip-on operation and a clear LCD make it accessible for both vehicle owners and professional technicians.
