Suzuki GP125 - Checking Ignition Coil

5-4
CHECKING IGNITION COIL
The ignition coil is essentially a transformer
which
changes
low
voltage
into
high.
For
this
reason there are two windings; the first (low
voltage
—
input
side)
is
the
primary
coil
and
the
second (high voltage — output) the secondary
coil.
Use
a
electro
tester
type
55-11
to
verify
ignition
coil
performance.
* Set the power switch to “OFF”
* Connect the coil test leads with the yellow tip
attached to the coils B/Y (ог B, ВИА) wire
and the black tip to the coils mounting
bracket (ground). Connect the high tension
leads with the red @) lead attached to the
spark plug cable and the black © lead to the
coils mounting bracket (ground).
Set the test selector knob to “IG. COIL”.
Switch the power ON
Note the spark in the spark gap window. It
should be strong and continuous, not inter
mittent, across a preset 8 mm (0.3 in) дар
Allow the spark to jump the test gap for at
least five minutes continuously, to insure
proper operation under the temperature con:
ditions of actual riding.

CHECKING
WITH
POCKET
TESTER:
A
SUZUKI
pocket
tester
or an
ohm
meter
may
be
used,
instead
of
the
electro
tester.
In
either
case,
the
ignition
coil
is
to
be
checked
for
conti
nuity
in
both
primary
and
secondary
windings.
Exact
ohmic
readings
are
not
necessary,
but,
if
the
windings
are
in
sound
condition,
their
conti
nuity
will
be
noted
with
these
approximate
ohmic
values.
