A large automotive electrical harness can contain hundreds of wires, dozens of connectors and several electronic components, such as relays and diodes.
Vehicles have become increasingly electrical over the years. This is not just power electronics, but also sensor data, communications and many other coordinated electrical signals. For aircraft or commercial vehicles, wire harnesses can be even more complex with hundreds of interconnection points.
Over the last 26 years, since the founding of CAMI Research Inc., customers and friends have asked why the company would focus its efforts on such a mundane, low-tech, and uninteresting device as a cable tester, particularly since a variety of such devices already existed.
Taking tests and waiting with hope for positive results is a stressful activity that most people perform only when absolutely necessary. For wire-harness assemblers, it’s a daily challenge.
When watching an operator test an automotive wire harness, one is reminded of old-time photos and TV skits about telephone switchboard operators of the 1950s and 1960s.
