Our wire harness testers help you identify potential issues before they become problems. This ensures the safety and reliability of your products. Our team uses industry-standard testing methods and the latest technology to deliver top-quality results. Also, our experts are always available to offer guidance and support.

Our testers for wire harnesses typically include several different types of tests, including the following:

  • Continuity Test: This test checks that there is a complete electrical path between two points in the wire harness.
  • Short Circuit Test: This test checks for any unintended electrical connections between wires or components in the wire harness.
  • High Voltage Test: This test checks that the wire harness can withstand high voltage levels without breaking down or malfunctioning.
  • Insulation Resistance Test: This test checks that the wire insulation is intact and able to resist current leakage.
  • Current Leakage Test: This test checks for any unintended current flow through the wire harness.
  • Connector Air Leak Test: This test checks for any air leaks in the connectors, which could lead to electrical problems or malfunctioning of the wire harness.

Our testers are designed to provide accurate readings and pinpoint any potential defects, helping you create products that perform flawlessly every time.

FAQ

What types of wire harness testing machines do you offer?

We offer automated wire harness testing machines including continuity testers, high-voltage (Hi-Pot) testers, functional testers, and customized end-of-line (EOL) testing systems. These are designed for automotive, EV, aerospace, and industrial wire harness applications.

Can your wire harness tester detect open circuits, short circuits, and wrong connections?

Yes. Our wire harness testers are designed to detect open circuits, short circuits, miswiring, and incorrect pin connections with high accuracy. This ensures every harness meets electrical and quality standards before dispatch.

Is the testing system customizable for our harness design and connector type?

Absolutely. Each wire harness tester is customized based on your harness drawings, connector types, number of pins, and testing requirements. Custom test jigs and fixtures are developed to ensure accurate and repeatable testing.

Can the tester handle multiple wire harness variants?

Yes. The system can be configured to handle multiple harness variants using programmable test recipes, quick-change test jigs, and modular fixtures. This reduces changeover time and improves production flexibility.

Does the machine support high-voltage (Hi-Pot) and insulation testing?

Yes. High-voltage (Hi-Pot) and insulation resistance testing can be integrated into the system based on your application requirements, especially for EV and aerospace harnesses where safety standards are critical.

Can test results be recorded and used for traceability?

Yes. The system can log test results for each harness, including pass/fail status and detailed reports. This supports traceability, audit requirements, and quality documentation for OEM and Tier-1 suppliers.

What is the typical cycle time for wire harness testing?

Cycle time depends on harness complexity, number of test points, and test type. Automated systems are designed to meet high-volume production requirements with fast and consistent testing cycles.

Can the tester be integrated into our existing production line?

Yes. Our wire harness testing machines can be integrated as standalone stations or as part of an automated production line, including end-of-line (EOL) setups with conveyors, marking, and rejection systems.

How does an automated tester reduce rework and field failures?

Automated testing ensures 100% verification of electrical connections before dispatch. This prevents defective harnesses from reaching customers, reducing rework, warranty claims, and field failures.

Is the system suitable for EV and aerospace wire harness testing?

Yes. Our testers are designed to meet the stringent requirements of EV and aerospace applications, including high-voltage testing, precision validation, and strict quality compliance standards.
