CHECKING THE IGNITION
Inspecting the magneto
- Remove the inspection cover, so as to be able to
reach the magneto connectors.
- Disconnect the Black /Red feed cable from the
coil and the 2-way connector in the White/Red
and the White/Yellow cables.
- Check that the resistance values are in line with
the following tables:
The values for consulting the table should be
read between 20º and 30º C.
- If the actual values are not the same as those on
the table, check the wiring before replacing the
mageto.
Inspecting the coil
- Withdraw the spark plug cap.
- Check the resistance of the secondary winding of
the coil between points A and B.
- The correct value between A and B: 5 - 6 kΩ.
- If the value of the resistance of the secondary
winding and the magneto are correct, the coil
assembly should be replaced.
Checking the spark plug cap
- Check the value of the resistance between the
terminals of the spark plug cap.
- The correct value of the resistance: 9 - 11 kΩ.
SWITCHES AND SENSORS
Ignition switch
- Remove the panels so as to be able to reach the
ignition lock connectors.
- Remove the ignition lock to carry out the continuity
check as in the attached diagram.
Code and function of the colours
BL - Blue .............Earth input
Wh/R - White/Red....Engine stop
Or - Orange ........Output and for battery accessories
Gr - Green ..........Input and Battery
- If the continuity test is not satisfactory, replace
the ignition lock.
- If the test is satisfactory, check the general condition
of the cables in the wiring.
