Because the operation of each limit switch is as
shown in the tables below, the DOWN side and
SLANT side are ON in the standard position and
there is continuity.
Because of this, the front venturi skirt drive circuit
turns transistor Tr2 ON, thereby turning the contact of
relay 1 ON. This causes current to flow from fusible
link (11) to the relay 1 contact, motor and earth,
operating the motor and moving the front venturi skirt
to the operated position.

At this time, the limit switches are also turned by the
motor, and when the operated position is reached,
the DOWN side contact of the limit switches becomes
OFF, relay 1 turns OFF and the motor stops. In the
same way, the rear spoiler drive circuit turns
transistor Tr3 and relay 2 ON, operating the motor
and moving the rear spoiler to the operated position.
When the operated position is reached, the SLANT
side of the limit switch becomes OFF, and the motor
stops.
