Allsun ALLOSUN Automotive Wire Piercing DC Tester — 6V/12V, Hook Probe, 59-Inch Cord, LED & Buzzer

Overview

The Allsun ALLOSUN Automotive Wire Piercing DC Tester is designed to help you verify wiring quickly and confidently. Built for DC circuits in the 6-12V range, it combines a slim, stainless-steel piercing probe with a durable insulated cord and a protective hook-cover. A clear usage note reminds users not to test above 15V and to avoid sensor or computer wiring, helping you choose the right tool for the job.

What makes it helpful

• Three interchangeable probes enable both touch-type and piercing-type testing for flexible workflows.
• Safe hook-cover design guards fingers during placement, reducing risk in busy work environments.
• Heat- and oil-resistant insulation protects the cord in automotive settings while the slim probe fits tight spaces.
• Hands-free operation with an end hook frees your hands, speeding up tasks and reducing downtime.
• Two high-visibility LEDs combined with a loud buzzer provide quick, easy-to-read status signals.

Versatile in real-world scenarios

Use it in the workshop to verify wiring when installing radios or brake controllers, and in campers or trailers to identify which wires control tail lights. It supports 6-12V circuits and is not recommended for sensor or computer wiring, ensuring you choose the right approach for each job.

Key advantages at a glance

• Long reach: a 59-inch cord lets you work without dragging or stretching cords.
• Reliable piercing: the slim stainless-steel probe locks onto wires for steady testing in hard-to-reach spots.
• Clear indicators: LEDs and a buzzer deliver immediate feedback for quick decisions on wiring status.

Usage tips

Operate within the voltage range of 6-12V and avoid voltages above 15V. For hands-free use, employ the end hook to secure the wire; if you prefer, you can remove the hook sleeve to use the probe alone. Always work with appropriate wiring and follow the stated guidelines.
