SUPPLEMENT--1982 MODEL

Dwell-angle
control
The dwell angle is electronically controlled by the
dwell angle control circuit so that it
increases
as the
engine speed increases. This is to save the electric power
at low engine speed, and to produce a spark of sufficient
strength at high engine speed.
(4)
Voltage regulating
A voltage
regulating
circuit is equipped in the cir-
cuitry. The voltage regulating circuit supplies an even
voltage (6 volts)
to
the other circuits in
the
igniter de-
spite variations in battery voltage. As a result, stable
operation of the igniter is ensured.
Moreover, the
voltage regulating circuit protects the circuitry from
surge currents in the power lines.
Safety Instruction:
There are a number of important precautions that
must be observed when servicing the transistorized
ignition system.
Failure to observe these precautions
can result in serious system damage. Learn and observe
all
the rules listed
below.
(1) Because of limited capacity of the voltage regulating
circuit in the IC igniter, do not disconnect the
battery leads or any other electrical connections
when
the
ignition switch is on, or while
the
engine is
running. This is
to
prevent IC igniter damage.
(2) Do not install the battery backwards. The negative
side is grounded. This is to prevent damage to the
diodes.
Non-Scheduled Maintenance:
Troubleahooting Guide:
If tro
uble
is suspected
in
the
ignition
system, check
the system by the following
"Ignition
System
TrOUble-
shooting Guide" shown in
fig.
Nl14. To use
this
chart,
follow
the arrows on the chart selecting a
"YES"
or
"NO"
arrow at each diamond-shaped step until you reach the
"E ND".
Each test
procedure
is explained individually.
Discription of Each Testing Procedure:
(1)
To
check the ignition spark
-Connect
the strobe light to
each
spark plug lead in the
manner prescribed by the manufacturer.
eTurn
on the main switch,
ignition
switch, and
engine
stop
switch.
ePush
the starter button with the clutch lever pulled in.
*Make
sure that the strobe light gose on and off
con-
tinuously.
(2)
To check
the dynamic ignition timing
Check the ignition timing with a
strobe
light
for
both
low
and high speed
operations.
Timinig advance begins
at about 1,400 rpm and reaches the maximum advance at
about 2,800 rpm.
As the result,
the
timing
must
be
checked at idle (low speed operation) and then above
3,000
rpm
(high speed operation) when it is fully
advanced.
The
ignition timing/engine speed relationship
is shown in fig. Nl12.

A. Inspection Window Cover
-Connect
a strobe light to the
#
1
or #6
spark plug
lead
in the manner
prescribed
by the manufacturer in order
to check the ignition timing under operating
conditions.
eTurn
on the main
switch,
the ignition
switch,
and the
engine
stop switch
.
Start
the
engine,
and direct th
e
strobe light at the timing marks through
the inspection
window.
eAt
idle speed, the
"F"
mark on
the
alternator
rotor
must be aligned with the timing mark on the alternator
cover for correct low speed ignition timing.
