Inspection & Testing



Spark plug wire integrity is vital for proper engine operation. A thorough inspection will be necessary to accurately identify conditions that may affect engine operation.

  1. Inspect for correct routing of the spark plug wires. Improper routing may cause cross-firing.
  2.  
  3. Inspect each wire for any signs of cracks or splits in the wire.
  4.  
  5. Inspect each boot for the following conditions:

    Tearing
     
    Piercing
     
    Arcing
     
    Carbon tracking
     
    Corroded terminal end
