Lisle’s Heavy-Duty Circuit Tester (28830) features a digital LCD display to accurately show DC voltage.
With an operating range of 3-49 volts DC to work on most vehicle electrical systems, the tool has 360° visibility of polarity.
The red light indicates positive polarity; the green indicates negative polarity.
It includes a long, 12’ coil cord and heavy-duty alligator clamp for secure connections.
The probe is insulated to prevent the possibility of shorting the side of the probe to other components.
The tool will not damage sensitive electronic components. (Not for use on airbags.)
