Ignition system troubleshooting guide
If trouble
is suspected in the ignition system, check
the system
by
the following
procedure.
An
example
of
troubleshooting is shown in Fig.
K18.
To
use
th is 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
on
the
pages
after the chart. This chart is
for
one third
of
the
ignition circuit
;
use
the same chart
for each other third
.

Engine Speed (rpm)
Check the ignition
timing
with a strobe light for both
low and high speed operation. Timing advance begins
at 1,050 -1
,200
rpm and reaches
the
maximum advance
at
2,750 -
3,050 rpm. As a result, the
timing
must be
checked
at
idle
(below
1,050
rpm) and then between
3,100-3,500 rpm when
it
is fully
advanced.
Check the timing as follows:
-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.
-Turn
on the
main
switch, the ignition switch, and the
engine
stop switch
.
Start the engine,
and direct the
strobe light at
the
timing
marks.
-Below 1,050 rpm, the
"F"
mark on the timing advancer
must be aligned with the timing mark above the ad-
vancer
for correct low rpm ignition timing (Fig. K22).
A. Strobe Light
B. Inspection Window
-Between 3,100
-
3,500 rpm, the timing mark on the
housing must be between the advanced timing mark on
the
advancer
(a pair of the
vertical
lines) for
correct
high
rpm ignition timing
(Fig.
K22).

-If low
speed
ignition timing is not correct, loosen the
mounting screws (3) of the pick-up coil assembly, and
turn the stator plate to adjust the timing; clockwise
rotation
advances
the
timing and counterclockwise
rotation
retards
it.
Re-check the timing.
-If low speed
ignition
timing is correct but high speed
ignition timing is
not
correct;
check that the
rotor
on
the timing advancer turns smoothly on the shaft by
hand and
that
no parts are visibly
damaged.
