Spark Plug Insulation Resistance Check

  1. Measure the insulation resistance of the spark plug. If the insulation resistance of the spark plug is under the limited value, clean the spark plug (Refer to SPARK PLUG CLEANING ).

    Limit: Minimum 10 MΩ 

  2. After cleaning, measure the insulation resistance again. Replace the plug unless it is within the limited value.
