Car Circuit Tester

This diagnostic tool consists of a transmitter and a receiver with a flexible tip approximately 18 cm long. Connect the transmitter in series with the circuit using the red and black alligator clips, then run the receiver along the wires: the insulation remains intact, with no direct contact or punctures. A beep and LED indicators show whether the circuit is open or shorted, and the sensitivity can be adjusted as needed. The TEST button allows you to check the device before starting. It operates on 6 to 42 V DC and is protected against voltage spikes and overloads. It is faster and safer than checking each wire individually, especially when the faulty wire is hidden in a bundle or conduit, behind a panel, under a rug, or behind trim. It helps locate a broken wire, identify a short circuit when a fuse keeps blowing, or check an electrical system before and after a repair or the installation of an accessory. Its design allows it to slide under the dashboard or into the engine compartment. It’s ideal for quick troubleshooting at the garage or at home, for both amateur and professional mechanics.
