5-5 ELECTRICAL SYSTEM
CAUTION
Numberical value may differ a little according
to the tester.
Please remind that there may be a defect
which can not be identified even though the
measurement by using the tester indicates a
low voltage.
The range of measurement adjust a [
unit.
IGNITION COIL
Pull out the spark plug.
Place it on the cylinder head after installing it at the
plug cap to obtain ground.
Push in the electric starter switch to rotate the starter
motor, to have the test of sparking performance.
If not emited spark or the spark bring out the orange
color, replace the ignition coil.
CAUTION
The ignition coil is marked the F for front, and
the R for rear.
If otherwise, it may occure severe damage to the
engine.
IGNITION COIL (Checking with Pocket Tester)
A pocket tester or an ohm meter may be used,
instead of the electro tester. In either case, the igni-
tion coil is to be checked for continuity in both prima-
ry and secondary windings. Exact ohmic readings are
not necessary, but, if the windings are in sound
condition, their continuity will be noted with approxi-
mate ohmic values.
