WITH THE IGNITION SW TURNED ON, THE CURRENT FLOWS TO TERMINAL 7 OF THE INTEGRATION RELAY THROUGH GAUGE FUSE.
VOLTAGE IS APPLIED AT ALL TIMES TO TERMINAL (A) 2 OF THE INTEGRATION RELAY THROUGH THE TAILLIGHT RELAY (COIL SIDE),
AND TO TERMINAL (A) 3 THROUGH THE HEADLIGHT RELAY (COIL SIDE).
1. NORMAL LIGHTING OPERATION
(TURN TAILLIGHT ON)
WITH LIGHT CONTROL SW TURNED TO TAILLIGHT POSITION, A SIGNAL IS INPUT INTO TERMINAL (A) 1 OF THE INTEGRATION
RELAY. ACCORDING TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 2 OF THE RELAY FLOWS FROM TERMINAL (A) 1 "
TERMINAL 2 OF THE LIGHT CONTROL SW " TERMINAL 11 " TO GROUND AND TAILLIGHT RELAY CAUSES TAILLIGHT TO TURN ON.
(TURN HEADLIGHT ON)
WITH LIGHT CONTROL SW TURNED TO HEADLIGHT POSITION, A SIGNAL IS INPUT INTO TERMINALS (A) 1 AND (A) 4 OF THE
INTEGRATION RELAY. ACCORDING TO THIS SIGNAL, THE CURRENT FLOWING TO TERMINAL (A) 3 OF THE RELAY FLOWS TO
TERMINAL (A) 4 " TERMINAL 13 OF THE LIGHT CONTROL SW " TERMINAL 11 " TO GROUND IN THE HEADLIGHT CIRCUIT, AND
CAUSES TAILLIGHT AND HEADLIGHT RELAY TO TURN THE LIGHT ON. THE TAILLIGHT CIRCUIT IS SAME AS ABOVE.
2. LIGHT AUTO TURN OFF OPERATION
WITH LIGHTS ON AND IGNITION SW TURNED OFF (INPUT SIGNAL GOES TO TERMINAL 7 OF THE RELAY), WHEN DOOR ON DRIVER'S
SIDE IS OPENED (INPUT SIGNAL GOES TO TERMINAL 6 OF THE RELAY), THE RELAY OPERATES AND THE CURRENT IS CUT OFF
WHICH FLOWS FROM TERMINAL (A) 2 OF THE RELAY TO TERMINAL (A) 1 IN TAILLIGHT CIRCUIT AND FROM TERMINAL (A) 3 TO
TERMINAL (A) 4 IN HEADLIGHT CIRCUIT. AS A RESULT, ALL LIGHTS ARE TURNED OFF AUTOMATICALLY.
