Trailer Electrical Connector Protection
sd mm 31.04.001
In some cases, failure of trailer cables occurs due to intrusion of chloride-based road deicing chemicals into the trailer connector. Once inside the connector, the chloride-based chemicals corrode the brass terminals and create bridging between positive and ground terminals.
- Wash out any existing grease, dirt, and corrosion on the trailer connectors with electrical contact cleaner spray.
- Grease the trailer connector with a lithium-based dielectric grease.
Note: The use of soap is not recommended for cleaning the electrical connector, as some soaps may increase the corrosion process.
