Checking the spark plug connector
300884-10
–
Measure the removed spark plug connector with a multimeter.
Spark plug connector
Resistance at: 20 °C (68 °F)
4.3… 5.7 k
Ω
» If the displayed value does not equal the specification:
–
Change the spark plug connector.
22.6
Checking the CDI controller
Info
Never check the CDI controller with a conventional measuring instrument. This can destroy highly sensitive electronic compo-
nents.
–
Check the cable and plug-in connection of the CDI controller. A functional check of the CDI controller is only possible on an igni-
tion test bench.
22.7
Checking the ignition coil
Condition
The fuel tank is removed.
–
Remove the spark plug connector.
–
Disconnect the ignition coil.
