3000GT VR-4 AWD V6-2972cc 3.0L DOHC MFI Twin Turbo (1998)
Turn Signal Lamp: Description and Operation
1. When operation is normal
-
When the ignition switch is switched to the ON position, battery voltage is applied (via the multipurpose fuse (11) and hazard switch) to the
turn-signal and hazard flasher unit.
-
When the turn-signal switch is switched to the LH position, Tr1 (within the flasher unit) is switched ON and OFF repeatedly. Then the contacts
of the relay 1 (also within the flasher unit) repeatedly switch from ON to OFF, causing the turn-signal lights and turn-signal indicator light LH
to flash.
-
When the turn-signal switch is switched to the RH position, Tr2 (within the flasher unit) is switched ON and OFF repeatedly. Then the
contacts of relay 2 (also within the flasher unit) repeatedly switch from ON to OFF, causing the turn-signal lights and turn-signal indicator light
RH to flash.
2. If one of the bulbs is burned out
-
If the LH (or RH) turn-signal light bulb is burned-out, the resistance of the turn-signal circuit as a whole increases, resulting in shorter ON and
OFF intervals of the LH Tr1 (or RH Tr2) and a higher flashing rate of the LH lights (or RH lights).
