2. Circuit and its function
The engine stop solenoid circuit is as shown at left.
Turn the key switch to the ON position, and the bat-
tery current flows both to the pull-in coil and the
holding coil. These coils are excited to attract and
lift the plunger.
Now the fuel injection pump is ready to get the
engine started.
Being attracted upward, the plunger pushes and
opens the contact, which discontinues the current
flow to the pull-in coil.
With the current still flowing to the holding coil, the
plunger stays in this position.
Turn the key switch to the OFF position, and the
current flow to the holding coil is also interrupted.
By the force of the return spring, the plunger comes
back to the original position. By so doing, the fuel
injection pump will be back to the engine-off status.
