Trailer Electrical Connector Lubricating

m2 mm 31.04.000

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.

Note: The use of soap is not recommended for cleaning the electrical connector, as some soaps may increase the corrosion process.

  1. Wash out any existing grease, dirt, and corrosion on the trailer connectors with electrical contact cleaner spray.
  2. Grease the trailer connector with a lithium-based dielectric grease.
