Check the pulse generator for an output signal – bipolar
plug (1) with green and red cable colors (also see circuit
diagram on opposite page):
– Apply the red measuring tip of the peak voltage
adapter to the green cable and the black measuring
tip to the red cable, disconnect plug (1) to disconnect
the CDI unit (2).
Multimeter reading: 6 volts +/- 0.5 volt
– Same measurement with CDI unit connected
Multimeter reading: 4 volts +/- 0.5 volt
Check the generator charging coil for the ignition
capacitor charge for output voltage – bipolar plug (3)
with black/red and red/white cable colors (also see circuit
diagram on opposite page).
– Apply the red measuring tip of the peak voltage
adapter to the black/red cable and the black
measuring tip to the red/white cable; disconnect plug
(3) to disconnect the CDI unit (2).
Multimeter reading: 35 volts +/- 5 volts
– Same measurement with CDI unit connected.
Multimeter reading: 210 volts +/- 10 volts
Check the primary voltage output (4) for ignition coil
control (also see circuit diagram on opposite page) for
output voltage (blue/white cable).
– Apply the red measuring tip (R) of the peak voltage
adapter to the black/white cable (ground) and the
black measuring tip (S) to the blue/white cable, CDI
unit (2) and ignition coil (5) connected.
Multimeter reading: 200 volts +/- 10 volts
STATIC IGNITION VALUES - KOKUSAN 4K-3A, B
Measuring conditions:
– Cold engine
– Seat and tank removed
–All plugs and the ground connections are in a non-corroding condition, plugs are tightly connected
– Battery charged (if installed) and the light switch turned off
–Gap between the rotor and the pulse generator is set to 0.75 mm
– Decompression lever is pulled
– Depress the kickstarter forcefully at least 5 times for each measurement
