Controllo impianto di accensione
All system check operations involving disconnec-
tion of the cables (inspections of connections and
devices that are part of the ignition circuit) must be
made with the engine turned off: otherwise the
control unit could be irreparably damaged.
It is therefore important and necessary that in case
of removal of the cables, when refitting attention is
paid to correctly reconnecting each cable to the
corresponding coupling respecting the distinct col-
our codings.

INSPECTIONS TO BE PERFORMED IN THE EVENT OF IGNITION IRREGULARITIES
In the event of failure and abnormal operation of the ignition, whose causes are not detectable by a
visual inspection, it is necessary first to replace the control unit with a corresponding, safely functional
replacement.
Remember that the disconnections and connections to replace the control unit must be performed when
the engine stopped.
If replacing it restores the ignition operation, the fault lies in the control unit, which obviously needs to
be replaced.
In the event that the failure persists, it is necessary to carry out checks on the alternator and on the
stator parts as follows:
After a visual inspection of the electrical connections, measurements are carried out on the loading coil
and on the pick-up using an Ohm meter, capable of detecting the resistance from 1 to 1000 ohms.
