Corrosion or rust visible inside generator enclosure, on wiring, or on engine components.

Safety first: Turn controller to OFF and disconnect battery before cleaning inside the enclosure.

• Dry and clean: Remove standing water and dry surfaces. Clean light corrosion from terminals with contact cleaner and a brush.
• Inspect seals: Check door gaskets, cable entry points, and roof seams for gaps. Replace damaged weatherstripping and seal penetrations with approved sealant.
• Drainage: Ensure enclosure drain holes are clear of debris.
• Protective coatings: Apply anti-corrosion spray to exposed terminals and hardware, especially in coastal areas.
