Improving the Quality of Testing Motor Racing Cables and Harnesses
By Margaret Bishop, Ph.D., CAMI Research, Inc. F
ounded in 2003, and located in Daytona Beach, Florida, Creative Motorsport Solutions (CMS) has grown from being a data system reseller to a company that now designs and
ty of manufacturing as aerospace parts. A few years ago, CMS set about finding a test system that would be accurate and flexible enough to han- dle high-mix, low-volume testing. “At that time, we were looking to attach a ‘primary’ connector to the tester with up to 79 pins and use the probe to identify correctness of the other pins. We did not want to build a mating interface for the many smaller connectors, but just have the system read out the name and pin number,” explains Colin Harmer, owner of CMS. “During our tester evaluation phase, we were drawn to CableEye’s versatility, especially its invaluable AutoBuild™ function, which allows us to have a test lab that talks to us. When set up for sec- ond-sided pinning, we probe each pin with the test probe, and the tester reads out the pin number, while displaying the same informa- tion on the screen.”

builds its own complex embedded electronics sys- tems for all types of racing vehicles in the motor- sport market. CMS also offers services for wiring system
design and manufacturing, and wire harness test- ing. It is one of the few motorsport wiring houses in the U.S. to utilize a CAD solution for wiring har- ness design. CMS customers include teams racing the Daytona 24 and Daytona 500. Motorsport looms are usually complex and mission-critical, requiring the same level of quali-
the wiring of an unknown cable or harness, using its “Learn Cable” function. This feature is especially useful when reverse engineering
parts for customers who have lost their schematics. In one test, the customer had an issue that
pointed at the corner looms as being suspect. “These were not looms we built, but because the CableEye tester is so flexible, we could quickly reverse engineer the loom, check it against the supplied drawings, perform a hipot test and gener- ate test reports showing the wiring in very little time,” says Harmer. In general, motorsport-type builds are typical- ly low-volume, which puts a premium on flexibility

with fixtures and ease of use and is a true delineator of the CAMI testers. CMS now easily hipot tests every product, which ensures that clients receive goods that are exactly to specification. By keeping records of all the tests, the compa-
ny can easily retest at a future point to ensure that there has been no change in the loom, for example, in post-race and post-crash diagnostics. “We find it really easy to generate, store and
print all the test documentation we need within CableEye,” says Harmer.
