Automotive DC Circuit Tester 6V-24V

This power circuit probe tester diagnoses electrical systems on cars, trucks, boats, trailers and motorcycles. It identifies polarity, checks continuity and activates components with a single hand-held tool. The built-in overload protection trips at 7A and sounds a buzzer to prevent damage. It suits professional mechanics and enthusiasts who need quick fault-finding on 6V to 24V DC circuits.

4-Metre Test Lead Reach

The 13 ft extension cable lets you probe circuits far from the battery without moving the tool. An auxiliary ground clamp connects directly through the unit for a stable reference. This reach is the single specification that decides whether the tester fits your workspace and vehicle size.

Simple Hook-Up with Audible Alerts

Clip the black lead to ground, touch the stainless-steel tip to the circuit and read the red or green LED for polarity. The buzzer sounds instantly on overload or continuity, so you hear faults without watching the display. The only common mistake is forgetting to reset the internal breaker after a 7A trip before continuing tests.
