SERVICE INFORMATION
•
When checking the ignition
system,
always follow the
steps
in the troubleshooting flow chart (page 1
5-3).
•
The transistorized ignition
system
use an electrically controlled ignition timing
system.
No
adjustments can be made
to
the
ignition timing.
•
A rough diagnosis can be made by identifying
the
cylinder
whose
spark timing
is incorrect.
•
The spark unit
may
be damaged if dropped. Also, if the
connector
is disconnected when
current
is
flowing, the excessive
voltage may damage the unit. Always
turn
off the ignition switch before
servicing.
•
A faulty ignition
system
is often related
to
poorly connected
connectors.
Check those connections before
proceeding.
•
Make sure the
battery is adequately charged. Using
the
starter motor
with
a weak battery results in
a slower engine crank¬
ing speed as well as no spark
at
the spark plugs.
•
Use spark plugs of the
correct
heat
range. Using spark plugs with an incorrect heat range
can
damage the engine.
Refer to section
2
of the Common Service
Manual.
•
For neutral switch inspection,
refer
to
section 25 of the
Common Service
Manual;
for switch
location, see page 1 5-2 of
this manual
(SYSTEM LOCATION).
•
For the ignition switch and engine
stop
switch inspection, check for continuity on the continuity chart of the WIRING
DIA¬
GRAM, page
18-1. Disconnect each switch
connector
inside the headlight
case (page
1-19)
and check it.
