CURRENT FROM THE BATTERY IS ALWAYS FLOWING FROM THE FL MAIN " HEADLIGHT RELAY (COIL SIDE) " TERMINAL 5 OF THE
DAYTIME RUNNING LIGHT RELAY (MAIN) AND TERMINAL 14 OF THE DIMMER SW, HEADLIGHT RELAY (COIL SIDE) " TERMINAL 3 OF
THE INTEGRATION RELAY " TERMINAL 4 " TERMINAL 13 OF THE LIGHT CONTROL SW, FL MAIN " DAYTIME RUNNING LIGHT
RELAY NO. 2 (COIL SIDE) " TERMINAL 17 OF THE DAYTIME RUNNING LIGHT RELAY.
1. DAYTIME RUNNING LIGHT OPERATION
WHEN THE ENGINE IS STARTED, VOLTAGE GENERATED AT TERMINAL L OF THE GENERATOR (ALTERNATOR) IS APPLIED TO
TERMINAL 11 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN).
IF THE PARKING BRAKE LEVER IS PULLED UP (PARKING BRAKE SW ON) AT THIS TIME, THE RELAY IS NOT ENERGIZED, SO THE
DAYTIME RUNNING LIGHT SYSTEM DOES NOT OPERATE. IF THE PARKING BRAKE LEVER IS RELEASED (PARKING BRAKE LEVER
SW OFF), THE SIGNAL IS INPUT TO TERMINAL 8 OF THE RELAY. THIS ACTIVATES THE RELAY ALSO, CURRENT FROM FL MAIN
FLOWES TO DAYTIME RUNNING LIGHT RELAY NO. 2 (POINT SIDE) " HEAD (UPR±LH) FUSE " TERMINAL 1 OF THE HEAD LH±HI "
TERMINAL 2 " TERMINAL 2 OF THE HEAD RH±HI " TERMINAL 1 " TERMINAL 4 OF THE DAYTIME RUNNING LIGHT RELAY NO. 3 "
TERMINAL 2 " TO GROUND, SO BOTH TAIL AND HEADLIGHT UP.
THIS IS HOW THE DAYTIME RUNNING LIGHT SYSTEM OPERATES. ONCE THE DAYTIME RUNNING LIGHT SYSTEM OPERATES AND
HEAD HAVE LIGHT UP, HEAD REMAIN ON EVEN IF THE PARKING BRAKE LEVER IS PULLED UP (PARKING BRAKE SW ON).
EVEN IF THE ENGINE STALLS WITH THE IGNITION SW ON AND THERE IS NO VOLTAGE FROM TERMINAL L OF THE GENERATOR
(ALTERNATOR), HEAD REMAIN ON. IF THE IGNITION SW IS THEN TURNED OFF, AND HEAD ARE TURNED OFF.
IF THE ENGINE IS STARTED WHILE THE PARKING BRAKE LEVER IS RELEASED (PARKING BRAKE SW OFF), THE DAYTIME RUNNING
LIGHT SYSTEM OPERATES AND TAIL, HEADLIGHT UP AS THE ENGINE STARTS.
2. HEADLIGHT OPERATION
*(WHEN THE LIGHT CONTROL SW AT THE HEAD POSITION)
WHEN THE LIGHT CONTROL SW IS SET TO HEAD POSITION, THE CURRENT FLOWING TO THE HEADLIGHT RELAY (COIL SIDE)
FLOWS TO TERMINAL 3 OF THE INTEGRATION RELAY " TERMINAL 4 " TERMINAL 13 OF THE LIGHT CONTROL SW " TERMINAL 11
" GROUND, TURNING THE HEADLIGHT RELAY ON.
THIS CAUSES THE CURRENT FLOWING TO THE HEADLIGHT RELAY (POINT SIDE) " DRL FUSE " DAYTIME RUNNING LIGHT RELAY
NO. 3 (COIL SIDE) AND DAYTIME RUNNING LIGHT RELAY NO. 4 (COIL SIDE) " GROUND, TURNING THE DAYTIME RUNNING LIGHT
RELAY NO. 3 AND NO. 4 ON. ALSO, CURRENT FROM THE HEADLIGHT RELAY (POINT SIDE) TO HEAD (LWR) FUSES " TERMINAL 1
OF THE HEADLIGHTS (LO) " TERMINAL 2 " GROUND, SO THE HEADLIGHTS (LO) LIGHT UP.
*(DIMMER SW AT FLASH POSITION)
WHEN THE DIMMER SW IS SET TO FLASH POSITION, CURRENT FLOWS FROM HEADLIGHT RELAY (COIL SIDE) " TERMINAL 14 OF
THE DIMMER SW " TERMINAL 9 " GROUND, TURNING THE HEADLIGHT RELAY ON. AT THE SAME TIME, SIGNALS ARE OUTPUT
FROM TERMINAL 12 AND TERMINAL 14 OF THE DIMMER SW TO TERMINAL 16 AND TERMINAL 5 OF THE DAYTIME RUNNING LIGHT
RELAY (MAIN), ACTIVATING THE DAYTIME RUNNING LIGHT RELAY (MAIN) AND ALSO THE DAYTIME RUNNING LIGHT RELAY NO. 2.
WHEN THE HEADLIGHT RELAY AND DAYTIME RUNNING LIGHT RELAY (MAIN) ARE ACTIVATED, THE HEADLIGHTS (LO AND HI) THEN
LIGHT UP.
*(DIMMER SW AT HIGH POSITION)
WHEN THE LIGHT CONTROL SW IS SET TO HEAD POSITION, A SIGNAL IS OUTPUT FROM TERMINAL 13 OF THE LIGHT CONTROL SW
" TERMINAL 4 OF THE INTEGRATION RELAY " TERMINAL 3 " TERMINAL 5 OF THE DAYTIME RUNNING LIGHT RELAY (MAIN).
WHEN THE DIMMER SW IS SET TO HIGH POSITION, A SIGNAL IS OUTPUT FROM TERMINAL 12 OF THE DIMMER SW TO TERMINAL 16
OF THE DAYTIME RUNNING LIGHT RELAY (MAIN). THESE SIGNALS ACTIVATE DAYTIME RUNNING LIGHT RELAY NO. 2, SO CURRENT
FLOWS FROM DAYTIME RUNNING LIGHT RELAY NO. 2 (POINT SIDE) " HEAD (UPR±LH) FUSE " TERMINAL 1 OF THE HEADLIGHT
LH±HI " TERMINAL 2 " DAYTIME RUNNING LIGHT RELAY NO. 4 (POINT SIDE) " GROUND, AND CURRENT ALSO SIMUTANEOUSLY
FLOWS FROM HEAD (UPR±RH) FUSE " DAYTIME RUNNING LIGHT RELAY NO. 3 (POINT SIDE) " TERMINAL 1 OF THE HEADLIGHT
RH±HI " TERMINAL 2 " DAYTIME RUNNING LIGHT RELAY NO. 4 (POINT SIDE), CAUSING THE HEADLIGHTS (HI SIDE) TO LIGHT UP.
