🔌 Function

Insulates a terminal or stud from the metalwork around it so the current cannot find an unintended path to earth.

⚠️ Common Signs of Failure

• Blown fuse, or a circuit that earths out when the terminal is disturbed
• Washer cracked, charred or melted
• Scorch marks or discolouration around the terminal
• Terminal loose because the insulating stack has crushed

🛠️ Service Notes

• Isolate the battery before disturbing the terminal
• Renew the insulating washer, bushing and plate as a set, since a single damaged piece lets the terminal earth
