ELECTRICAL SYSTEMS OPERATION (Contd)
e.
Directional Signal System Operation.
The directional signal system is identical on all models covered in this manual and consists of the following
major components and circuitry:
A
FRONT COMPOSITE LAMP - Receives power from turn signal control through circuits 460 and 461 to
indicate turning direction.
B
LIGHT SWITCH - Provides battery power to the directional signal switch through circuits 460 and 461, and to
the stoplight switch through circuit 75.
C
STOPLIGHT SWITCH - Closing this switch allows power to flow from the light switch through circuit 75 to
circuit 22 to the directional signal switch.
D
REAR COMPOSITE LAMP - Receives power from turn signal control through circuit 22-460 and 22-461 to
indicate turning direction.
E
DIRECTIONAL SIGNAL SWITCH - A four-position switch that directs power to the composite and signal
lamps through circuits 460, 461, 22-460, and 22-461 to indicate direction of turn.
F
TURN SIGNAL FLASHER - Receives power through circuit 467A and sends intermittent current to the signal
lamp through circuit 467B.
