SYSTEM OUTLINE
WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 18 OF THE WIPER AND WASHER SW, TERMINAL 2 OF
THE WASHER MOTOR AND TERMINAL 4 OF THE WIPER MOTOR THROUGHT THE WIPER FUSE.
1. LOW SPEED POSITION
WITH THE WIPER SW TURNED TO LOW POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW
TERMINAL 7 TERMINAL 2 OF THE WIPER MOTOR
AT LOW SPEED.
2. HIGH SPEED POSITION
WITH WIPER SW TURNED TO HIGH POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW
TERMINAL 13 TERMINAL 1 OF THE WIPER MOTOR
RUN AT HIGH SPEED.
3. INT POSITION
WITH WIPER SW TURNED TO INT POSITION, THE RELAY OPERATES AND THE CURRENT WHICH IS CONNECTED BY RELAY
FUNCTION FLOWS FROM TERMINAL 15 OF THE WIPER AND WASHER SW
OPERATES THE INTERMITTENT CIRCUIT AND THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW
TERMINAL 7 TERMINAL 2 OF THE WIPER MOTOR
THE INTERMITTENT OPERATION IS CONTROLLED BY A CONDENSER'S CHARGED AND DISCHARGED FUNCTION INSTALLED IN
RELAY AND INTERMITTENT TIME IS CONTROLLED BY A TIME CONTROL SW TO CHARGE THE CHARGING TIME OF THE
CONDENSER.
4. MIST POSITION
WITH WIPER SW TURNED TO MIST POSITION, THE CURRENT FLOWS FROM TERMINAL 18 OF THE WIPER AND WASHER SW
TERMINAL 7 TERMINAL 2 OF THE WIPER MOTOR
AT LOW SPEED.
5. WASHER CONTINUITY OPERATION
WITH WASHER SW TURNED ON, THE CURRENT FLOWS FROM TERMINAL 2 OF THE WAHSER MOTOR
OF THE WIPER AND WASHER SW
WASHER IS JET. THIS CAUSES THE CURRENT TO FLOW WASHER CONTINUOUS OPERATION CIRCUIT IN TERMINAL 18 OF THE
WIPER AND WASHER SW
