Hazard Flasher Relay: Description and Operation
CIRCUIT OPERATION
The electronic flasher relay in the junction block supplies battery voltage to the turn signal/hazard switch circuitry in the multi-function switch.
When the ignition switch is OFF, the hazard flashers will operate but the turn signals will not.
Circuit A7 from fuse 15 in the Power Distribution Center (PDC) powers the electronic flasher through fuse 13 in the junction block.
In the RUN position, the ignition switch connects circuit A1 from fuse 8 in the Power Distribution Center (PDC) to circuit A22. Circuit A22 feeds
the flasher relay through fuse 6 in the junction block. Circuit Z1 provides ground for the relay
Circuit L5 from the flasher relay connects to the multi-function switch to supply power to the turn signal circuits. The multi-function switch
connects to the right rear turn signal lamps on circuit L60 and the left rear turn signal lamp on circuit L61. Circuit L64 from the switch feeds the
right front turn signal lamp and side marker lamp. Circuit L65 feeds the left front turn signal lamp and side marker lamp.
Circuit L12 from the flasher relay connects to the multi-function switch to supply power to the hazard flasher circuits. The multi-function switch
connects to the rear turn signal lamps on circuits L60 and L61 and the front turn signal and side marker lamps on circuits L64 and L65.
