C I R C U I T OPERATION
Stop Lights
Voltage is applied to the Stop Lights through
the Stop HAZ Fuse, Brake Switch, and the
Turn-Hazard Switch Assembly. When the brake
pedal is depressed, the Brake Switch will close
and the Stop Lights will operate.
Turn Lights
Battery voltage is applied to the LH Stop-
Turn Light through the Turn B/U Fuse, Turn
Flasher, Hazard Switch, and the Turn-Left
Switches in the Turn-Hazard Switch Assembly.
Both Turn Left Switches close to the left at the
same time. When the switch connected to the
YEL wire closes, the LH Stop-Turn Light oper-
ates. When the Switch connected to the LT
BLU wire closes, the LH Front Turn Light and
the LH Turn Indicator light. They begin to
flash when current heats up the timing element
in the Turn Flasher, and it repeatedly opens and
closes the circuit.
The RH Turn Lights operate in a similar way
when the Turn Right Switches are closed to the
right.
(For SE Models Only)
If the Brake Switch is closed at the same
time as the Turn Left Switches, the LH Turn
Lights continue to operate through the Turn
Flasher. The RH Stop-Turn Light at the rear
glows steadily as long as the Brake Switch is
closed.
(For GT Models Only)
If the Brake Switch is closed at the same time
as the LH Turn Lights, the Brake Lights
remain on. The Turn Lights continue to operate
independently of the Brake Lights.
