Automotive Circuit Tester 6-24V DC

This power circuit probe tester operates on 6-24V DC vehicle battery systems. It includes a 4.5m test cable and overload protection rated at 8A. The tool suits professional mechanics and DIY owners diagnosing car, motorcycle, boat or construction-vehicle electrical faults.

LCD Display with Polarity Indication

The built-in LCD shows voltage values with +2% accuracy. Red and green LEDs instantly reveal positive or negative polarity. A front LED flashlight illuminates dark work areas while you test battery voltage, continuity, lamps, motors, short circuits and poor grounding.

Sustained Use Safety Limits

Overload protection triggers at 8A to prevent damage during extended testing sessions. The unit operates continuously between -10 and 60 degrees Celsius at up to 80% relative humidity. Sparks may occur at the probe tip, so flammable environments and any AC or 36V+ sources must be avoided.

Questions about this item

How does the 6-24V DC range translate when I connect it to a 12V or 24V vehicle battery?

The tester draws power directly from the vehicle battery, so it works on both 12V and 24V systems without extra adapters; the display shows live voltage with ±2% accuracy across the full range.

What does the 8A overload protection actually limit during a short-circuit trace?

The built-in protection trips at 8A, capping the current the probe can draw while you hunt for a short so the tool and wiring stay safe.

Will the 4.5m cable reach from the battery to the rear lights on a typical pickup?

At 4.5m (14.8ft) the lead stretches from a front-mounted battery to most rear lighting circuits on pickups, SUVs and boats without an extension.
