The Spark Plug Produces No Sparks - Honda 2010 CBX 250 Workshop Manual

CBX250
INVESTIGATION OF FAULTS
• Before carrying out the diagnosis of breakdowns of the system, inspect the following: defect in the spark plug
Connection inadequate noise dampening layer or spark plug Penetration of water in the layer
suppressive noise (leakage of winder secondary ignition coil) • In case that there are no sparks in the cylinder,
replace the ignition coil temporarily on the other which is in good condition. The test of spark. If there are
spark, the ignition coil original is with fault. The initial voltage of winder primary of the ignition coil is the
voltage of the battery, with the power switch in the position ON, and the switch of emergency in the position
RUN. (The engine of the motorcycle not be operated with the starter motor).

The spark plug produces no sparks.

Causes Probables (Siga el orden numérico al verificar)
1. Incorrect Connections adapter voltage of peak. 2. Impedance of
multitester too low: less than 10 M ©
too low (low battery). 4. The time to sample the tester and pulse
measured are not synchronized (the system will be normal in
case of at least one of the voltages measures are higher than the
specifications). 5. Connection loose or inappropriate in the ter-
minal or circuit interrupted in the ignition system. 6. Defect in
the switch of side stand in the switch deadlock. 7. Circuit inter-
rupted or connection inappropriate in the cables connected
to the item no. 6. • Circuit breaker of side stand: cable
Green / White • circuit breaker deadlock: cable Light green / Red
8. Control Module of ignition (ICM) with fault (when the items no. 1
to 7 are normal).

switch or in the switch of emergency. 4. Connection loose or
inappropriate in the terminal or circuit interrupted in the con-
nector of the ICM. 5. There are no voltage in the black / White of
the ICM. 6. Connection inadequate or circuit interrupted in the
cable Green (earth) of the ICM. 7. Defect in the switch of side
stand in the switch deadlock. 8. Circuit interrupted or
connection inappropriate in the cables connected to the item no.
7. • Circuit breaker of side stand: cable Green / White •
circuit breaker deadlock: cable Light green / Red 9. Defect in the
adapter of voltage in pico. 10. Fault on the pulse generator
power (Measure voltage of pico). 11. Control Module of ignition (ICM)
with fault (when the items no. 1 to 10 are normal).
1. Spark plug ignition defect or leakage in the winder secondary ignition
coil. 2. Ignition Coil with fault.
1. Impedance of multitester too low: less than 10 M ©
Speed motor drive too low (low battery). 3. The time to sample
the tester and pulse measured are not synchronized (the
system will be normal in case of at least one of the voltages
measures are higher than the specifications). 4. Pulse generator
power with fault (when the items no. 1 to 3 are normal).
1. Adapter from the voltage of peak with fault. 2. Pulse generator power
with fault.
