ELECTRICAL SYSTEM
[4] FUEL PUMP
An electro magnetic fuel pump uses a transistor that
causes the pump to start pumping fuel when the main
switch is turned to the “ON” position.
Therefore, fuel is supplied to the fuel injection pump
regardless of engine speed. This pump is driven by the
battery. It can therefore be operated even with the
engine being stopped.

[5] ENGINE STOP SOLENOID
■ D722-E-BX
The timer relay is provided to actuate the engine stop
solenoid approx. 10 seconds to stop after the main
switch is turned from ON position to OFF position.
Flowing of the battery current into the coil while the
timer relay contact point is closed attracts the plunger to
actuate the stop lever of the injection pump. When the
battery current stops, the plunger is returned to the
original position by the spring.

■ D905-E-BX
Flowing of the battery current into the engine stop
solenoid, the plunger (2) move to right side so that the
movement of control rack (4) becomes free. When the
battery current stops, the plunger (2) is returned to the
original position by the spring to keep the control rack (4)
in “No fuel injection” position.
