Zzxker 6V-24V DC Circuit Probe Tester

The Zzxker power circuit probe tester is a corded automotive electrical tool designed for 6V, 12V and 24V DC systems. It serves professional mechanics and vehicle owners who need to diagnose wiring faults, check polarity and activate components directly from the battery.

Multi-function voltage.

The tester measures DC voltage across the 6V to 24V range and displays values on an integrated LCD screen. It performs continuity checks, signal circuit tests and component activation while the built-in circuit breaker protects the unit and the vehicle battery from overload during fault finding.

Overload alert with audible warning and worklight

When excessive current is detected the LED changes from red to green and a beep sounds, prompting the user to disconnect the battery clips. A built-in flashlight illuminates the probe area for repairs in low light and the ergonomic switch allows one-handed polarity reversal in tight spaces.

Questions about this item

Will the 6-24 V probe work on my classic 12 V car without damaging the original wiring?

The tester is rated for 6 V to 24 V DC systems, so a 12 V vehicle is well within range and the built-in overload protection will cut power if excess current is detected.

How can I confirm the LCD display and flashlight are functioning correctly after I connect the clamps?

Clamp the red and black clips to the battery terminals; the LCD should show the battery voltage and the flashlight will illuminate, proving both features are active.

Does the kit include the auxiliary ground clamp shown in the photos, or must I buy it separately?

The package contains the probe unit with integrated LCD and flashlight, red and black battery clamps, and the auxiliary ground clamp — no extra accessories are required.
