Ignition (Kokusan 4K-3)

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.

Checking the stator (Kokusan 4K-3)

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 if the measured values deviate significantly
from the setpoint values.
