Trouble shooting in the ignition system
Before checking the ignition system check
●
if the ignition lock is in position
●
if the emergency off switch is in the position
●
if the neutral control lamp is on
●
if the motorcycle can be started with the clutch pulled
●
if the battery is charged

Check if an ignition spark is produced when the starter is operated.
Proceed as follows:
– Pull the spark plug connector.
– Disconnect the spark plug connector from the ignition cable.
– Hold the free end of the ignition cable approximately 5 mm from
ground.
– A strong spark should be visible when the electric starter is now
operated. If the battery is discharged below the threshold level
required for electric starting, please use the kickstarter.
– If a spark is visible, replace the spark plug connector.
– Twist out the spark plug and insert it into the spark plug connector.
– Connect the spark plug to ground. A strong spark should be visible
at the electrode when the electric starter is now operated. If this is
not the case, the spark plug connector or the spark plug is defect.
– If no spark is produced during the first test, perform the following
checks:
●
Does the ignition’s power supply line (orange) carry battery voltage?
●
If this is not the case, check the ignition lock, the emergency off
switch and, if applicable, the side stand relay as well as the
corresponding parts of the cable tree.
– If the ignition is sufficiently supplied with power and no spark is
produced, check:
●
ground connection of CDI unit and ignition coil
●
the cable between CDI unit and ignition coil
●
pulse generator
●
stator
●
ignition coil
