Hide 19100P 3.INSPECT SPARK PLUG

NOTICE:
·

Be careful not to damage the iridium tip or platinum tip of the spark plug.

·

Check the iridium tip visually as it is easily damaged.

·

Never attempt to adjust the electrode gap of a used spark plug.

·

If a spark plug is extremely dirty with oil, etc., replace it.

·

Replace a spark plug if it is damaged.

·

If a spark plug has been struck or dropped, replace it.

·

When installing a new spark plug, do not remove the protective cap from the spark plug tip until just before installing the spark plug to the engine.

Spark plug (terminal part) - Body ground Always 10 MΩ or higher


HINT:

If a megohmmeter is not available, perform the following simple inspection instead.




b.

Alternative inspection method.

i.

Connect the GTS to the DLC3.


ii.

Turn the power switch on (IG).
