With the benefits of electronics come the problems associated with wires. There can be nothing as frustrating as trying to track down an electrical short. Many times mechanics become so frustrated that they simply run a new wire rather than try to find the actual short. But as truck electronic circuitry becomes more complex, a quick rewiring solution may not exist. One good place to start preventing most electrical shorts is with the connector lubricant. In an industry full of fine dust, mud and periodic acid-washes, it's the lubricant that protects the metal connectors from corrosion and eventual shorts. A thin film of lubricant reduces the mating force between male and female component ends by as much as 80%, making assembly more efficient and ensuring solid connections. An effective lubricant also protects electrical-connector surfaces from oxidation corrosion due to harsh operating environments and from vibrations produced by engine operation. In addition to preventing the atmospheric problems of oxidation corrosion, the proper connector grease can minimize oxidation from contact abrasion on tin/lead connector surfaces, known as fretting wear. To achieve long-term performance, the lubricant must protect against both mechanical and chemical breakdowns. Synthetic hydrocarbon oil may be a good choice. Synthetic grease manufacturers avoid formulations with gellants that can actually dissolve when exposed to water. Synthetic greases include hydrocarbon molecules that are more stable than the molecules of simple petroleum oils, resulting in lower maintenance costs and less downtime for the fleet owner. High-viscosity synthetic hydrocarbon oils don't evaporate as fast or oxidize as readily, thus increasing connector life. Keywords: lubricant, electrical, connection, connector, Nye Lubricants
