Ignition
General information
The measurements described below will only reveal severe problems.
Coil short circuits leading to weak ignition sparks or low generator
output, respectively, can only be detected with the help of an ignition
test bench. In the case of malfunction always check the cables and the
plug and socket connections of the ignition system first.
Make sure to select the correct measuring range when performing
measurements.
The CDI unit can be checked only on the ignition test bench.
Spark plug
Electrode distance: 0.60 mm (0.024 in)
Insulator
Check for cracks and fissures.
!
CAUTION
!
A
LWAYS USE A SPARK PLUG WITH RESISTOR. OTHERWISE PROBLEMS CAN OCCUR IN
THE
CDI UNIT
.
Check stator and pulse generator
Use an ohmmeter to perform the following measurements:
NOTE: The measuring must be performed at a temperature of 20° C.
Otherwise significant deviations must be expected.
Replace the stator and/or the pulse generator if the measured values
deviate significantly from the setpoint values.
