All-in-One Automotive Wire Tracer & Circuit Tester
This automotive wire tracer works with DC 6–42V systems and helps locate open circuits, short circuits, broken wires, current leaks, and continuity issues without damaging wire insulation. It is a practical diagnostic tool for cars, trucks, DIY repair, automotive technicians, electricians, and maintenance work.

Sound & Light Signal Indication
Equipped with a sensitive transmitter and receiver, this open and short circuit finder provides clear test feedback through LED lights and beeping tones. The low-battery indicator helps prevent unexpected shutdowns, while the anti-interference design reduces background noise for more reliable troubleshooting.

Precise Open Circuit Location
Use the adjustable sensitivity settings to help pinpoint open circuit breakpoints. When an open circuit is detected, the transmitter shows a flashing green light. The receiver gives a strong signal and rapid beep in normal areas, then the signal weakens or disappears near the breakpoint for easier fault locating.

Fast Short Circuit Detection
This circuit short finder helps identify short circuits quickly. When a short circuit is detected, the transmitter flashes red, while the receiver shows a solid red light and rapid beeping near the fault area. This makes electrical diagnostics faster and helps reduce guesswork during repair.

Easy Continuity Testing Mode
The dedicated continuity testing mode makes wire checks simple. Attach the red and black test clips to both ends of the wire: a steady green light indicates good continuity, while no light means the wire may be faulty or broken. Suitable for quick wire testing on cars, trucks, and other electrical equipment.
