Electrical system
THE CONNECTION DIAGRAMS ARE IN THE ELECTRICAL SYSTEM SECTIONS; PAY ATTENTION
TO THESE DIAGRAMS AS THEY SHOW THE CONNECTOR/COMPONENT AS VIEWED FROM
THE CABLE HARNESS SIDE, THAT IS LOOKING AT THE CABLES WHEN GOING OUT OF THE
"MAIN" CABLE HARNESS AND INTO THE CONNECTOR/COMPONENT.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
AND CONTROL SECTION IN THE ELECTRICAL SYSTEM CHAPTER.

PARAMETERS
Ignition advance
ACTIVATION
Right coil (rear cylinder):
The auxiliary injection relay (No. 29 in the wiring diagram, placed under helmet compartment, right side)
is energised for 5 seconds and the grey/red cable of the coil is closed to ground for 2 ms per second.
Disconnect the 4-way connector of the fuel pump to be able to hear the relay and injector activation.
The continuity of the wiring is necessary for correct activation: no error indications are displayed in case
of lack of activation.
Left coil (front cylinder):
The auxiliary injection relay (No. 29 in the wiring diagram, placed under helmet compartment, right side)
is energised for 5 seconds and the orange/green cable of the coil is closed to ground for 2 ms per
second. Disconnect the 4-way connector of the fuel pump to be able to hear the relay and injector
activation. The continuity of the wiring is necessary for correct activation: no error indications are dis-
played in case of lack of activation.
