🔌 Function

Spreads the clamp load of its fastener across the mating face and protects that face from being marked as the fastener is tightened.

⚠️ Common Signs of Failure

• A fuse that blows or a breaker that trips again as soon as the circuit is made live
• Charring, melting, tracking marks or a burnt smell around the terminal stud
• The washer visibly cracked, crushed flat or squeezed out from under the terminal
• Heat discolouration at the terminal, or a stud that has worked loose in its mounting

🛠️ Service Notes

• Isolate the batteries before disturbing the terminal; the insulating washer is what keeps a live stud clear of the housing or bracket around it
• Rebuild the stack in exactly the order it came apart, with the insulator between the parts it separates and nothing bridging across it
• Fit it unstressed and handle it carefully — a cracked or crushed insulator no longer insulates, however sound it looks in place
• Tighten the terminal nut to the figure in the workshop manual for your engine: overtightening splits the washer, undertightening leaves a hot joint that will char it
• With the batteries still isolated, confirm with a meter that the stud is clear of earth before reconnecting
