Constructed with a gold-plated brass probe tip, this circuit tester identifies positive, negative, and open circuits while supplying power or ground to activate components. It functions as a digital voltmeter for capturing min/max voltage readings and is compatible with systems up to 24 V. The 20-foot (6.1 m) lead provides the necessary reach for testing relays and cooling fans across the vehicle.
