Stop guessing and start pinpointing. This advanced automotive circuit tracker lets you detect open and short circuits, trace wires, and diagnose faults without damaging insulation. Whether you're working in tight engine compartments, under dashboards, or behind panels, this tool helps you get the job done faster, safer, and more accurately.
Non-Invasive Testing: Identify open or short circuits and wire breaks without stripping or damaging the insulation.

Flexible Gooseneck Probe: Navigate through tight spaces like under carpets, dashboards, or bundled wiring with the 7" bendable probe.
Clear Audio Feedback: The receiver emits a beeping sound when it locates a fault, making diagnosis quick and intuitive.

Adjustable Sensitivity: Customize signal strength for precise tracking in different environments.
LED Indicators: Instantly know if there’s continuity, short, or open circuit using the transmitter’s LED status lights.

Safe for DC Systems: Compatible with DC voltage from 6V to 42V—ideal for modern car electrical systems.
No Wire Piercing: Simply clamp the leads; no need for physical contact with the wire core.


1 × Signal Transmitter (with test leads & mode selector)
1 × Signal Receiver (with built-in speaker and test button)
1 × Flexible Sensor Probe
1 × Storage Case for safe transport
1 × User Manual
Note: 9V battery not included.

Connect the red and black clips of the transmitter to the wire or circuit to be tested.
Switch the mode on the transmitter to either "TONE" (for tracing) or "CONT" (for continuity).
Power on the receiver and adjust the rotary volume/sensitivity dial.
Move the sensor probe along the wire. A beep will indicate signal presence.
Stop at the break or short spot — beep weakens or disappears, identifying the problem location.
✅ Use the correct probe angle as illustrated: align the sensor parallel to the wire for best results.
