ATE Pro Tools 70107 12V/42V Hybrid Automotive Logic Probe

Designed for use on today’s wide range of automotive electrical systems, the Automotive Logic Probe (12V/42V Hybrid) is a reliable testing tool for diagnosing circuits in 12V, 24V, and 42V hybrid vehicles. Whether you’re servicing a modern hybrid system or working with conventional 12 or 24 volt systems, this probe makes voltage testing quick and safe. With dual-color LEDs—blue for 12/24V and red for 42V—you can instantly identify the voltage you’re working with. It’s computer-safe, drawing only 3 milliamps at 12 volts, making it a safe option when working on sensitive electronic systems found in newer vehicles.

The 12-foot retractable wire provides extended reach under the hood or chassis, then automatically coils back to stay organized in your toolbox. A super sharp probe tip ensures you get clean contact through insulation or terminals, and the heavy-duty insulated ground clip secures firmly without damaging wiring. From auto repair shops to municipal fleet garages, this logic probe supports quick, visual voltage checks without the guesswork—ideal for diagnostics, repairs, and maintenance on everything from passenger vehicles to heavy-duty trucks.
