Why Replace the Audio Wiring Harness?

The audio harness is exposed to humidity, vibrations, and temperature variations inherent to the marine environment. Over time, connectors can oxidize, sheaths can crack, and wires can become brittle, leading to progressive malfunctions of the audio system.

Total absence of sound despite a powered audio system
Static or intermittent cuts
Short circuit detected in the audio circuit
Oxidized connectors or visibly damaged cables
Audio error message on the onboard console

It is recommended to inspect the audio harness at the beginning of the season or after 50 hours of navigation, especially if the tender has been stored outdoors or exposed to saltwater. Preventive replacement ensures the reliability of the audio system throughout the season.
