- Apply Dielectric Grease to Connections: Protect battery terminals, fuse blocks, and plug receptacles with marine-grade dielectric grease to lock out moisture and oxidation.
- Inspect Wiring and Fuses Seasonally: Periodically check electrical panels, ground buses, and breaker switches to ensure secure connections before heading into rough offshore conditions.
