The Volture Auto Circuit Tester – 4–36V DC is a professional automotive diagnostic tool designed for quick and accurate electrical testing on 12V and 24V vehicle systems. Built for workshops, installers, mechanics, off-road enthusiasts, and DIY users, this versatile tester simplifies fault finding, voltage checks, polarity identification, and circuit testing across a wide range of automotive applications.

Featuring a clear LED digital voltage display with backlight, the tester provides fast and accurate voltage readings between 4V and 36V DC. Integrated polarity indication uses colour-coded LEDs to instantly identify positive and negative connections, while the built-in buzzer provides audible confirmation during testing.
