39/IGNITION SYSTEM 120
300933-10
– Measure high voltage output of ignition coil against ground.
Ignition coil
Resistance of secondary winding
at: 20 °C (68 °F)
2.025… 2.475 kΩ
» If the measured value differs from the setpoint value:
– Change the ignition coil.
– Fit and connect spark plug connector.
300960-10
– Connect the special tool to the multimeter.
Peak voltage adapter (58429042000) ( p. 145)
Info
When using the peak voltage adapter, the measurement range of the multi-
meter must be set to DCV.
– Disconnect the ignition coil.
– Connect the black measuring lead of the special tool to ground. Connect the red
measuring lead to the input plug of the ignition coil.
– Activate the kickstarter.
