Spark Plug Insulation Resistance Check

SPARK PLUG INSULATION RESISTANCE CHECK




1. Measure the insulation resistance. If the insulation resistance of the spark plug is under the limited value, clean the plug within 20 seconds using a sand blast type plug cleaner.
2. After cleaning, measure the insulation resistance again. Replace the plug unless it is within the limited value.

Limit: Minimum 10 Mohms
