SPARK PLUG CABLE TEST
NOIGIGA
Hold the spark plug cable about 6 - 8 mm C.24 - .31~ in.) away
from engine proper (grounding portion such as cylinder block)
and crank engine to verify that sparks are produced.
SPARK PLUG TEST
NOBGIFIA
Connect the spark plug to the high tension cable, ground outer
electrode (main body). and crank engine. In the atmosphere,
only short sparks are produced because of small discharge gap.
If the spark plug is good, however, sparks will occur in
discharge gap (between electrodes). In a defective spark plug,
no sparks will occur because~of leak of insulation puncture.
SPARK TEST - ENGINE CANNOT BE CRANKED ~~=
If spark test IS performed by cranking while the catalyst IS hot,
unburned aas WIII be supplled to the catalyst, and this is not
desirable to the catalyst.
For this reason, use the tollowing methods which allow spark
test to be performed without cranking.
