•
In case there is a short circuit to ground connection of PIN 12 of the instrument panel con-
nector:
•
Check the ground insulation of the sensor connector pink cable:
•
If connected to ground, restore the cabling. If insulated from ground, check correct resistance
of the sensor:
•
if not OK, replace the sensor; if OK, replace the instrument panel
RUN/STOP switch
Function
It tells the control unit if the rider wishes to enable
engine start-up or to keep the engine running.
Operation / Operating principle
If the driver wants to shut off the engine or to dis-
able engine start-up, the switch should be open,
i.e. the Marelli control unit should not detect volt-
age at PIN 26 of the control unit connector.
Level in electrical circuit diagram:start-up ena-
bling switches.
Location:
•
sensor: right light switch
•
connector: next to the headstock, right
side
Electrical characteristics:
•
STOP position: the circuit is open
•
RUN position: closed circuit (continui-
ty)
PIN:
pink/yellow cable (looking at the cabling):
•
voltage 0 V with engine kill in STOP;
•
12V if engine kill in RUN.
Blue/Green cable (cable harness side): always voltage 12 V (with key on)
DIAGNOSIS
•
The engine does not start: disconnect the connector and check, with the switch set to RUN,
that there is continuity between the two grey/light blue and red/white cables (sensor side):
if absent replace the sensor; if present carry out the check procedure on the connector; if
not OK restore the cabling; if OK verify, with the key ON, the presence of voltage on the
blue/green cable (cable harness side); if absent, restore cabling; if present verify insulation
