ANALYZING SPARK PLUG
Engine conditions can be analyzed by the tip deposits near the electrode.
SPARK PLUG TEST (WHEN ENGINE CAN BE CRANKED)
Connect the spark plug cable. Ground the outer electrode (main body), and crank the engine. In the atmosphere, only short sparks are produced
because of the small discharge gap. If the spark plug is good, however, sparks will occur in the discharge gap (between the electrodes). In a defective
spark plug, no sparks will occur because of a leak through the insulation.
