🔌 Function

The distributor cap contains the high-voltage terminals that route ignition-coil output to the correct spark-plug lead. It also insulates the terminals and rotor path from moisture, salt and arcing.

Common signs of failure / service requirement:

• Crossfire, backfiring or random-cylinder misfire

• Hard starting in damp or humid conditions

• Carbon tracking, burnt terminals or internal arcing

• Cracks, corrosion or green deposits inside the cap

• Rough idle and loss of power under acceleration
