2.11 Analysis of ignition system
Dismantle the cover of brake light and check
whether its bulb is burned-out.
Brake light doesn
illuminate.
Replace the bulb of
brake light.
With a lead,make short circuit between
two connection end of brake light
switch or two lead end.
After short circuit,brake light still
doesn
’
t illuminate.
After short circuit,brake light
can illuminate.
The switch of brake light is
adjusted unproperly or the
inner connecting point has bad
connection.
Rub the power lead of brake light switch
with cathode wire with a screwdriver or a
lead.Check the spark.
When rubbing ,there
is no spark.
T h e p o w e r l e a d b e t w e e n
ignition switch and brake light
switch has shor t circuit or
open circuit.
When rubbing,there is
spark.
The lead between brake
light switch and brake light
has short circuit or open
circuit.
No
Yes
No
Yes
Dismantle high-voltage wire and
check whether there is spark spurt.
Engine starts hard.
Fire
No fire
Spark plug is
dagmaged.
Cut off the connecion of charging coil
of generator and triggering coil and
respectively measure the voltage.
Reconnect it.Turn off the ignition switch and
observe the high voltage coil.
Measure the DC resistance of
two coils.
T h e f l y w h e e l
rotor of generator
loses magnetism
seriously.
Ignition switch is
damaged.
Electronic ignitor is
damaged.
Replace it.
Ignition coil has open circuit
or short circuit.
R e p a i r o r
replace it.
Cut off the power export end of
ignition and measure the voltage.
Charging and triggering
coil have short circuit or
open circuit.
Add magnetism
or replace it.
R e p a i r o r
replace it.
has voltage
no voltage
Replace it.
