⚠️ Common Signs of Failure

• Cracked or heat-damaged insulator
• Moisture or carbon tracking inside the connector
• Connector will not mate or lock correctly

🛠️ Service Notes

• Note how the insulator sits and which way round it goes before taking it out — its whole job is keeping two things apart, and it only does that fitted correctly
• Renew rather than reuse anything cracked, crushed, hardened, charred or oil-soaked; a degraded insulator has already stopped doing its job
• Fit to clean, dry faces with the original fastener arrangement, tightened only to the figure in the workshop manual for your engine — crushing an insulator defeats it
• Look for why the old one failed, since the heat, chafe, vibration or leak that finished it will do the same to the new one
