🔌 Function

Covers and electrically insulates the high-current starter terminal while shielding the connection from moisture and debris.

⚠️ Common Signs of Failure

  • Cap split, hardened or missing
  • Exposed live terminal capable of shorting to ground
  • Green corrosion or moisture at the cable lug
  • Heat damage caused by a loose high-resistance connection
  • Intermittent cranking from a contaminated or corroded terminal

🛠️ Service Notes

  • Clean and inspect the seating face on the housing as well as the cap — most leaks past a cap are the seat or the seal rather than the cap body
  • Renew any separate O-ring or gasket that goes with the cap, and lubricate rubber seals lightly with clean oil or grease so they slide home instead of rolling or tearing
  • Do not over-tighten a cap into a plastic or aluminium housing; it seals on its gasket or O-ring, not on force, and stripped threads mean a much bigger repair
  • Where a cap blanks a port during a repair, keep it fitted right up to the moment of assembly so nothing enters the opening
  • Check the cap is fully home and that any retaining clip, lanyard or locking tab is secure before returning the boat to service
