CDI unit
Check the wires and connectors of the CDI unit.
The operation of the CDI unit can only be checked on a specially
designed test bench for ignitions.
IMPORTANT: NEVER CHECK THE CDI UNIT WITH STAN-
DARD MEASURING EQUIPMENT AS THIS COULD IRREPA-
RABLY DAMAGE HIGHLY SENSITIVE ELECTRONIC COMPO-
NENTS.
It is also possible to replace the control unit with one that is
known to be in working order to determine whether it is opera-
ting properly.
Checking the ignition coil
– Disconnect all the cables and unplug the spark plug.
– Using an ohmmeter, take the following measurements:
NOTE: The following measurements correspond to the nominal
values only at a temperature of 20° C.
If the measured values differ considerably from the nominal va-
lue, replace the ignition coil.

Troubleshooting the ignition system
Before checking the ignition system, verify the following:
• Emergency switch in on position.
• Battery charge.
• Main fuse.
Check if a spark is produced when the engine is started by fol-
lowing these steps:
– Remove the spark plug cap.
– Separate the spark plug cap from the ignition cable.
– Keep the free end of the ignition cable about 5 mm for an
earth connection.
– When the starter motor is operated, a bright electrical spark
should be produced. If the battery charge is very low, use the
kickstart.
– If a spark is produced, refit the spark plug cap.
– Unscrew the spark plug and insert it into the spark plug cap.
– Keep the spark plug connected to earth. When the electric
start is operated, a bright spark should be produced at the
electrode. If that is not the case, either the spark plug cap or
the spark plug is defective.
– If a spark is not produced at the first attempt, check the igni-
tion switch and the wiring harness components.
– If the ignition system is correctly powered but no spark is pro-
duced, check the following:
• Earth connection of the CDI unit and the ignition coil.
• Wire connecting the CDI unit to the ignition coil.
• Stator.
• Ignition coil.
