Circuit Description

Voltage is applied from the turn fuse to the normally closed pole of the turn signal switch through circuit 539, when the ignition switch is in the RUN, BULB TEST or START position. This position feeds the hazard lamp/turn signal lamp flasher through circuit 1508. Voltage is applied from the turn signal switch to circuit 14 at terminal A7 of connector C201 and to circuit 18 at terminal E7 of C201, when the turn signal switch is in the TURN LEFT position. Voltage is then applied to the following lamps:
^ The left front turn lamp
^ The rear turn lamp
^ The indicator lamps

The lamps flash ON and OFF as current flow heats the timing element in the hazard lamp/turn signal lamp flasher, continuously opening and closing the circuit. For right turn lamps, circuit 15 terminal A6 of C201 and circuit 19 terminal E6 of C201 are used.

When the park lamps and the turn lamps are ON, voltage is applied to both terminals of the front side marker lamp causing the marker lamp to be OFF. Voltage is applied to only 1 terminal of the marker lamp. This causes the marker lamp to flash ON when the front turn lamp is OFF. The turn lamp and the marker lamp continue to flash ON and OFF, out of sequence, until the turn signal switch is turned OFF.
