Phillips Industries notes that corrosion in electrical systems adds quite a bit of cost to routine maintenance for fleets. Just like when corrosion eats away at exterior surfaces on vehicles, when it enters electrical circuits, the cost is high. Phillips said it knows this and directs much of its testing and product development to finding solutions. One example of the consequences of corrosion on electrical systems discovered through the Phillips test method is that tractorArailer connections are not always adequately protected. For instance, the J560 (7-way) connector is the only automotive connection that is routinely opened and exposed directly to harmful environmental conditions. When coiled cables are unplugged from the trailer side only, they remain "live" and need to be stored properly. Unfortunately, many times they are not.
