1994 TOYOTA CAMRY condenser

METER, ANALOG
Current flow activates a magnetic
coil which causes a needle to
move, thereby providing a relative
display against a background
calibration. LED (LIGHT EMITTING DIODE)
Upon current flow, these diodes
emit light without producing the
heat of a comparable light. IGNITION COIL
Converts low±voltage DC current
into high±voltage ignition current
for firing the spark plugs. 1. SINGLE
FILAMENT
GROUND
The point at which wiring attaches
to the Body, thereby providing a
return path for an electrical circuit;
without a ground, current cannot
flow.Current flow causes a headlight
filament to heat up and emit light.
A headlight may have either a
single (1) filament or a double (2)
filament. BATTERY
Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto's
various electrical circuits.
CAPACITOR (Condenser)
A small holding unit for temporary
storage of electrical voltage.
CIRCUIT BREAKER
Basically a reusable fuse, a circuit
breaker will heat and open if too
much current flows through it. Some
units automatically reset when cool,
others must be manually reset.
DIODE
A semiconductor which allows
current flow in only one direction.
DIODE, ZENER
A diode which allows current flow
in one direction but blocks reverse
flow only up to a specific voltage.
Above that potential, it passes the
excess voltage. This acts as a
simple voltage regulator.
FUSE
A thin metal strip which burns
through when too much current
flows through it, thereby stopping
current flow and protecting a
circuit from damage.
FUSIBLE LINK
A heavy±gauge wire placed in
high amperage circuits which
burns through on overloads,
thereby protecting the circuit.
The numbers indicate the cross±
section surface area of the wires.HORN
An electric device which sounds a
loud audible signal.
LIGHT
Current flow through a filament
causes the filament to heat up
and emit light.
METER, DIGITAL
Current flow activates one or
many LED's, LCD's, or fluorescent
displays, which provide a relative
or digital display.
MOTOR
A power unit which converts
electrical energy into mechanical
energy, especially rotary motion. CIGARETTE LIGHTER
An electric resistance heating
element.
DISTRIBUTOR, IIA
Channels high±voltage current
from the ignition coil to the
individual spark plugs.2. DOUBLE
FILAMENT HEADLIGHTS

Fusible Link.)

WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF WASHER MOTOR, TERMINAL 4 OF REAR WIPER
RELAY AND TERMINAL 1 OF REAR WIPER MOTOR THROUGH THE WIPER FUSE.
1. REAR WIPER NORMAL OPERATION
WITH THE IGNITION SW TURNED ON AND REAR WIPER AND WASHER SW TURNED ON, THE CURRENT FLOWING TO TERMINAL 4
OF REAR WIPER RELAY FLOWS TO TERMINAL 6 OF RELAY " TERMINAL 1 OF REAR WIPER AND WASHER SW " TERMINAL 16 "
TO GROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE CURRENT TO TERMINAL 4 OF RELAY FLOWS TO TERMINAL 1 "
TERMINAL 4 OF REAR WIPER MOTOR " MOTOR " TERMINAL 2 " TO GROUND AND CAUSES THE MOTOR TO OPERATE THE
WIPER.
2. REAR WIPER INTERMITTENT OPERATION
WITH THE IGNITION SW TURNED ON AND REAR WIPER AND WASHER SW TURNED TO INT POSITION, THE CURRENT FLOWING TO
TERMINAL 4 OF REAR WIPER RELAY FLOWS TO TERMINAL 3 OF RELAY " TERMINAL 10 OF WIPER SW " TERMINAL 16 " TO
GROUND. AS A RESULT, THE RELAY OPERATES AND CURRENT FLOWS FROM TERMINAL 4 OF RELAY " TERMINAL 1 " TERMINAL
4 OF REAR WIPER MOTOR " MOTOR " TERMINAL 2 " TO GROUND, CAUSING THE MOTOR TO ROTATE TO OPERATE THE WIPER.
AT THIS TIME THE CONTACT IN THE WIPER MOTOR CLOSED AND THE CURRENT FLOWS FROM TERMINAL 1 OF REAR WIPER
MOTOR " TERMINAL 3 " TERMINAL 2 OF REAR WIPER RELAY " TERMINAL 1 " TERMINAL 4 OF REAR WIPER MOTOR "
TERMINAL 2 " TO GROUND.
THUS, THE INTERMITTENT±STOP CIRCUIT OPERATES, THE CONDENOR IN THE CIRCUIT CHARGES AND THE WIPER CONTINUES TO
OPERATE UNTIL REACHING THE STOP POSITION. AFTER THE WIPER STOPS, CURRENT DOES NOT FLOW TO THE
INTERMITTENT±STOP CIRCUIT FROM TERMINAL 2 OF RELAY, BUT THE CONDENSER DISCHARGES CURRENT INTO THE
INTERMITTENT CIRCUIT AND THE CIRCUIT OPERATES UNTIL THE CONDENSER DISCHARGE ENDS. AS A RESULT, THIS DISCHARGE
INTERVAL BECOMES THE INTERMITTENT TIME.
WHEN THE CURRENT IS DISCHARGED COMPLETELY, THE CURRENT FLOWING TO TERMINAL 4 OF RELAY FLOWS TO TERMINAL 3
" TERMINAL 10 OF REAR WIPER AND WASHER SW " TERMINAL 16 " TO GROUND.
THEN, THE CURRENT IN TERMINAL 4 OF RELAY FLOWS FROM TERMINAL 1 " TERMINAL 4 OF MOTOR " MOTOR " TERMINAL 2 "
TO GROUND AND ROTATES THE MOTOR. THROUGH REPEITION OF THIS PROCESS, INTERMITTENT OPERATION OF THE REAR
WIPER OCCURS.
3. WASHER OPERATION
WITH THE IGNITION SW ON AND THE REAR WIPER AND WASHER SW IS TURNED STRONGLY (WASHER SW ON), CURRENT FLOWS
FROM TERMINAL 2 OF WASHER MOTOR " TERMINAL 3 " TERMINAL 2 OF REAR WIPER AND WASHER SW " TERMINAL 16 " TO
GROUND SO THAT THE WASHER MOTOR ROTATES AND WINDOW WASHER EJECTS THE SPRAY, ONLY THE WHILE THE REAR
WASHER SW IS TURNED, WHEN THE REAR WIPER SW IS OFF, AND THE REAR WIPER AND WASHER SW IS THEN TURNED IN THE
OFF DIRECTION, WASHER LIQUID WILL ALSO SPLAY.
