The EM415PRO Automotive Circuit Tester is a professional diagnostic tool designed to quickly locate short circuits, open circuits, broken wires, current leaks, and intermittent faults without damaging insulation.
Using a transmitter and receiver system, this tool allows you to trace wires through looms, panels, carpets, conduits, and tight spaces with ease. The direction indicator and tone detection eliminate guesswork, helping you pinpoint faults faster and more accurately.
Suitable for cars, trucks, tractors, boats, RVs, and other 6–42V DC systems, the EM415PRO is ideal for mechanics, auto electricians, workshops, and serious DIY users.
