GENERAL INFORMATION
INTRODUCTION
The headlamp switch has 3 positions, ON, PARK
(parking lights) and OFF. Two circuits, L2 and L20
connect the headlamp switch to the headlamp dim-
mer/optical horn switch located in the multi-function
switch. The multi-function switch feeds the low and
high beams of the headlamps.
DESCRIPTION AND OPERATION
PARKING LAMPS
Circuit A3 in the Power Distribution Center (PDC)
connects to a bus bar in the fuse block. One of the
four circuits powered by the bus bar is circuit F33.
Circuit F33 connects to the headlamp switch. A 40
amp fuse in the PDC protects the A3 circuit. A 15
amp fuse, in cavity 2 of the fuse block, protects the
F33 circuit.
The headlamp switch has 3 positions, ON, PARK
(tail lamps) and OFF, plus a dimmer switch. When
the headlamp switch is in the PARK or ON position,
the switch connects circuit F33 to circuit L7. From
the headlamp switch, circuit L7 branches to power
the front parking lamps and rear tail lamps, lavalier
lamps, side marker lamps, and rear license plate
lamp.
GROUND CIRCUIT
Circuit Z1 provides ground for the parking lamps,
headlamps, lavalier lamps, tail lamps, side marker
lamps and rear license plate lamp although different
grounding points are used. Circuit Z1 also provides
the ground path for the headlamps and turn signals.
HELPFUL INFORMATION
²Check for a blown 40 amp fuse in the PDC.
²Check for a blown fuse in cavity 2 of the fuse
block.
²For the left front parking lamp, turn signal, side
marker lamp and left headlamp, the Z1 circuitgrounding point is the left side of the radiator closure
panel.
²For the right front parking lamp, turn signal,
side marker lamp and right headlamp, the Z1 circuit
grounding point is in the right fender side shield.
²Circuit L7 also feeds the radio, if equipped.
²When the headlamp switch is in the PARK or
ON position, the dimmer circuit, F33, also connects
to circuit E1. Circuit E1 powers the ash receiver
lamp, transmission range indicator lamp, instrument
panel cluster illumination lamps, HVAC control
lamp, heated rear window lamp, and radio lamp. A 4
amp fuse, in cavity 12 of the fuse block, protects cir-
cuit E1.
HEADLAMPS
The headlamp switch has 3 positions, ON, PARK
(parking lights) and OFF. Two circuits, L2 and L20
connect the headlamp switch to the headlamp dim-
mer/optical horn switch located in the multi-function
switch. The multi-function switch feeds the low and
high beams of the headlamps.
HEADLAMP SWITCH IN OFF OR PARKING
LAMP POSITION
Circuit A3 originates in the Power Distribution
Center (PDC) and supplies battery voltage for the
headlamp switch. A 40 amp fuse protects the A3 cir-
cuit. The headlamp switch has an internal 24 amp
circuit breaker that connects circuit A3 to either the
L2 or L20 circuits, depending on switch position.
In the OFF and PARK positions the headlamp
switch feeds the L20 circuit that connects to the
multi-function switch. Circuit L20 powers the high
beam circuit when the operator flashes the head-
lamps with the turn signal stalk of the multi-func-
tion switch. When the operator flashes the
headlamps with the stalk, the multi-function switch
connects the L20 circuit to the L3 circuit. The L3 cir-
cuit feeds the high beam of the headlamps.
HEADLAMP SWITCH IN ON POSITION
When the headlamp switch is in the ON position,
it connects the A3 circuit from the PDC to circuit L2.

DESCRIPTION AND OPERATION
HELPFUL INFORMATION.................. 4WIPERSÐINTERMITTENT................. 4
DESCRIPTION AND OPERATION
WIPERSÐINTERMITTENT
The intermittent windshield wiper system is pow-
ered by a 20 amp fuse located in the fuse block. This
fuse is HOT in the RUN and ACCESORY position.
This system has three modes of operation, INTER-
MITTENT, LOW, and HIGH.
When the ignition switch is in the RUN or ACCE-
SORY position, power is supplied on the F13 circuit
to the windshield wiper switch and wiper motor. The
wiper motor is case grounded and the switch logic
and relay control uses its own ground on the Z2 cir-
cuit to the right instrument panel center support.
When the operator moves the switch to LOW speed
position, battery voltage is passed through the switch
to circuit V3, which connects to the LOW speed
brushes of the wiper motor. If the switch is moved to
the HIGH speed mode of operation, power is
switched to the V4 circuit and to the HIGH speed
brushes of the motor.
When the delay mode of operation is selected cir-
cuits internal to the switch power up the logic and
relay control. The internal control supplies power to
the LOW speed area of the switch (V3 circuit) and
cycles the wipers. The amount of delay between
wiper cycles is dependent on switch position. All
relays and internal logic in the switch are not ser-
viceable and should be replaced as an assembly.As the windshield wiper motor turns, the park
switch internal to the motor moves from its grounded
position to the powered RUN position. When the
wiper switch is turned OFF, the V5 circuit is used to
prevent the wipers from stopping in any position but
park.
The intermittent windshield wiper system is also
equipped with a pulse wipe feature. To activate this
feature the operator presses the washer switch
momentarily. When the washer switch CLOSES, a
voltage signal is sent to the internal logic and relay
control. The control will cycle the wipers. In addition,
the wipers are placed in the maximum delay posi-
tion.
The windshield washer uses a pump motor inside
of the windshield washer fluid reservoir. When the
washer switch is pressed, power is supplied on the
V10 circuit to the pump motor. Ground for the pump
motor is the Z1 circuit and terminates at the left
headlamp ground.
HELPFUL INFORMATION
²Check the 20 amp fuse in cavity 15 of the fuse
block.
²Check the ground strap on the windshield wiper
motor.
²For the intermittent wiper system a ground is
dedicated to the wiper switch.
