motor, and when the standard position is reached, the
UP side contact of the limit switches becomes OFF, and
the motor stops.
In the same way, the rear spoiler drive circuit turns
transistor Tr4 and relay 3 ON, operating the motor and
moving the rear spoiler to the standard position. When
the standard position is reached, the FLAT side of the
limit switch becomes OFF, and the motor stops.

Moving from operated position to standard position
When the front venturi skirt and rear spoiler are in the
operated position, each drive circuit outputs a standard signal in any of the cases 1 - 4 for the following order of
conditions 1, 2 and 3.
Because the operation of each limit switch is as shown
in the tables below, the UPside and FLAT side are ON
in the operated position and there is continuity. Because
of this, the front venturi skirt drive circuit turns transistor
Tr1 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 standard position.
At this time, the limit switches are also turned by the
