How to avoid corrosion when splicing wire harness

Updated Nov 16, 2017

Phillips Industries has published a technical bulletin in this month’s Qwik Tech Tips to aid service providers when servicing 7-way cables.

“If done improperly, repairs to the 7-way harness can expose the wiring to moisture and corrosion causing contaminants that can wick their way throughout the electrical system in a short matter of time,” Phillips writes. “This can create costly downtime for further repairs, and/or lead to lighting failure, making a driver more susceptible to CSA violations, or worse, possible accidents on the road.”

To ensure corrosion free repairs are made when splicing into the 7-way harness, Phillips Industries goes on to list six key steps. The company also notes that “while its possible to make completely sealed repairs to the electrical system when splicing, wires should never be pierced for testing. Even the tiniest pin hole will open up a gateway to allow corrosion causing contaminants to wick their way into the electrical system.

“When making repairs to the electrical system, heat shrink terminals and heat shrink tubing should be used to seal the repair and lock out moisture and corrosion causing contaminants.”
