Ignition circuit
1) Check the state of the spark plug (clean it with
a metallic brush, remove all incrustations, blow it
with compressed air, and replace it if necessary).
2) Without removing the stator, perform the checks
described below:
After a visual inspection of the electrical connec-
tions, carry out the measurements on the charging
coil and pick-up (see table), and check for con-
tinuity using the special tester, 020331Y.
If the continuity checks or the inspections on the
coil and pick-up are incorrect, proceed by replac-
ing the stator, otherwise replace the ECU.
Remember to detach the ECU wirings when the
engine is not running.
