Fuel pump
Function
Fuel pump: keeps pressure of the injectors supply
duct.
Low fuel: tells to the instrument panel about low
fuel
Operation / Operating principle
Low fuel: it is a resistance that if correctly supplied
varies its electrical resistance if it is damped or not
by petrol.
Level in electrical circuit diagram:
Injection load relay
Location:
•
on the vehicle: on the tank.
•
connector: on right rear frame (4-ways
black).
Electrical characteristics:
PIN 1-2: 0.5 - 1 ohm; PIN 3-4: you do not need to
measure the component electrical resistance
since it works correctly with suitable supply from
the instrument panel only. Check correct operation
as follows: connect in series a bulb of approxi-
mately 2 W: it should turn on if the tank is in
reserve, otherwise, it remains off.
Pin out:
1. + 12 V
2. ground connection
3. ground connection
4. + 12 V (signal)

DIAGNOSIS INSTRUMENT: ACTIVATION
Fuel pump
NOTE: The injection relay (No 33 in the wiring diagram, position under the saddle, next to the battery
positive, CHECK, however, the identification of the relay with the colour of the cables) is energised for
