leave a service loop at each connector rather than pulling a branch tight\n \u003c\/li\u003e\n \u003cli\u003e\n  Push every connector home until the lock latches and protect the joints with a marine dielectric grease — an intermittent electrical fault is far more often a partly seated or salt-corroded pin than a broken wire\n \u003c\/li\u003e\n \u003cli\u003e\n  Renewing the harness is the right repair where insulation is chafed, brittle or oil-soaked, or where corrosion has tracked inside the connector bodies; patch repairs in a damp engine bay tend to fail again, and any single conductor that is repaired should be joined with tinned marine cable of the same gauge, a proper crimp and adhesive-lined heat-shrink\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔄 Supersession \u0026amp;
