Switching to Mode I activates the power circuit probe tester, which supports 4 operating modes: AC/DC voltage, resistance, and diode. The electrical probe tester allows users to instantly check 12V-24V electrical systems.

Switch the V200 Pro All-in-One Circuit Tester Kit to Mode II and you'll be able to use the Circuit Breaker Finder, which can easily locate breaker points, broken connections, broken wires, current leaks with tone changes, and even trace wires/cables without damaging the insulation.

The VDIAGTOOL V200 Pro Power Circuit Probe Kit generates activation signals to electrical components such as automotive lights, engines, windshield wipers, radiator fans, relays, fuel injectors, and more to troubleshoot electrical problems.

This car power tool is equipped with short-circuit protection. Once overloaded, it will automatically shut down and restart, which is a safety measure to protect the device and the car's electronic equipment.
