15-30 ELECTRICAL SYSTEM
The ignition system produces extremely high volt-
age. Do not touch the spark plug, ignition coil or ig-
nition coil lead while the engine is running, or you
could receive a severe electrical shock.

Ignition Coil Inspection
Measuring Arcing Distance
The most accurate test for determining the condition of
the ignition coil is made by measuring arcing distance using
the coil tester for the 3-needle method.
Remove the ignition coil (see Ignition Coil Removal/Instal-
Connect the ignition coil (with the spark plug cap installed
on the spark plug lead) [A] to the tester [B], and measure
the arcing distance.
To avoid extremely high voltage shocks, do not
touch the coil body or leads.
If the distance reading is less than the specified value, the
ignition coil or spark plug cap is defective.
3 Needle Arcing Distance
To determine which part is defective, measure the arcing
distance again with the spark plug cap removed from the
ignition coil lead. Remove the cap by turning it counter-
If the arcing distance is subnormal as before, the trouble
is with the ignition coil itself. If the arcing distance is now
normal, the trouble is with the spark plug cap.
