If faulty or failed operation persists, conduct the

following checks on the generator and on the sta-

tor components:

After a visual inspection of the electrical connec-

tions, it is possible to perform measurements on

the stator winding and pick-up (see table), using

the specific multimeter.

If, during the checks on the charge coil and the

pick-up, anomalies are found, replace the stator

and other faulty parts.

Disconnect the connector on the flywheel housing

and measure the resistance between each of the

two contacts and the earth.

Ignition circuit

All the control operations of the system that require

the disconnection of cables (checks of the con-

nections and the devices making up the ignition

circuit) must be done with the engine off: if this is

not done, the controls might be irreparably dam-

aged.
