🔌 Function

Sacrifices itself to galvanic corrosion so the folding propeller and the drive metal around it are protected.

⚠️ Common Signs of Failure

• Ring wasted to a fraction of its original thickness
• No wastage at all, which points to a poor electrical bond
• White powdery corrosion or pitting on the propeller and drive
• Mounting face corroded, so a clean metal contact cannot be made
• Fixings seized or corroded away
