Why use a circuit tracer?

Cable tracer for car – Track short circuits and open wires without damaging the insulation

When working with a car's electrical system, it can be tempting to start removing or stripping cables to identify the problem. However, this can lead to further damage and costly repairs. With a car circuit tracer, you can quickly and efficiently track short circuits and open wires without having to remove the insulation.

Advantages of our circuit tracer

  • Tracking without damaging the insulation: Identifies both open circuits and short circuits.
  • Fast troubleshooting: With the help of a transmitter and receiver, you can efficiently locate the problem.
  • Safe use: The device is adapted for use on vehicles with circuits up to 42V.

Step by step: How to use the circuit tracer

  1. Preparations: Make sure the car's ignition is off before you start. Always use protective equipment for added safety.
  2. Connect the transmitter: Connect the transmitter to the circuit or part of the wiring harness that you suspect has a defect.
  3. Use the receiver: Move the receiver along the suspected circuit or cable. The receiver will emit an audible signal when an interruption or short circuit is identified.
  4. Locate the problem: Once you have identified where the fault is, you can take action to fix the problem without having damaged the insulation.
