Ignition static parameter measurement with peak voltage adapter
Measurement conditions:
– cold engine
– remove the number holder
– loosen the spark plug, connect it and keep it to ground
– all connector couplings and connections to ground must be free of corro-
sion signs
– for each measurement strongly press the kick start pedal at least 5 times
fully down.
Check if the impulse transmitter gives an output signal – white/red and white/
blue cables:
– the red prod of the peak voltage adapter on the white/red cable, the
black prod on the white/blue cable, then separate the connector (1); in
this way the CDI unit (2) is disconnected.
reading on multimeter: 10 volt +/- 1 volt
– Same measurement, but with CDI unit connected
reading on multimeter: 6 volt +/- 1 volt
Check CDI unit voltage supply on output voltage
– green/red and black cables:
– the red prod of the peak voltage adapter on the green/red cable, the
black prod on the black cable, then separate the connector (1).
reading on multimeter: 40 volt +/- 5 volt
– Same measurement, but with CDI unit connected
reading on multimeter: 35 volt +/- 5 volt
Check the condenser charge coil on output voltage –
– black/red and green/white cables:
– the red prod of the peak voltage adapter on the black/red cable, the
black prod on the green/white cable, then separate the connector (1)
reading on multimeter: 270 volt +/- 20 volt
– Same measurement, but with CDI unit connected
reading on multimeter: 230 volt +/- 20 volt
Check the primary voltage output that controls the ignition coil
on the output voltage (orange cable):
– the peak voltage adapter red prod to the ground, and the black one to
the orange cable, CDI unit and ignition coil connected
reading on multimeter: 230 volt +/- 20 volt
WARNING: if upon one check it is not possible to measure a voltage
value,
we recommend to check the continuity across the cables before re-
placing the parts.
