Fuel Pump Control System - MV Agusta Brutale 675 Workshop Manual

FUEL PUMP CONTROL SYSTEM

When the ignition switch is turned to the ON position, the fuel pump motor is started by the current supplied by
the battery.
As the CPU possesses a timer function, the pump motor stops turning three seconds after the ignition switch has
been brought to the "ON" position. If the starter motor turns the electric motor shaft during or after the three sec-
onds, the motor rotation signal is sent to the CPU that, by controlling the pump relay, makes the pump motor func-
tion continuously.
When the ignition switch is switched to the "OFF" position, the control of the pump relay is interrupted and con-
temporaneously also the control of the injectors and the ignition coils, thereby causing the engine to switch off.
