DESCRIPTION AND OPERATION
ELECTRONIC FLASHER RELAY
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 Cen-
ter (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 sig-
nal 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.
TURN SIGNALS
When the operator selects the right turn signal,
the multi-function switch connects circuit L5 from
8W - 52 TURN SIGNALS
8W-52 TURN SIGNALS
the flasher relay to circuits L60 and L64. Circuit L64
feeds the right front turn signal lamp and side
marker lamp. Circuit L60 feeds the right rear turn
signal lamp. Circuit L64 also splices to power the
right turn signal indicator lamp in the instrument
cluster.
When the operator selects the left turn signal, the
multi-function switch connects circuit L5 from the
flasher relay to circuits L61 and L65. Circuit L61
feeds the left rear turn signal lamp and side marker
lamp. Circuit L65 feeds the left front turn signal
lamp. Circuit L65 also splices to power the left turn
signal indicator lamp on the instrument cluster.
Circuit Z1 provides ground for the turn signal
lamps.
HAZARD FLASHERS
When the operator selects the hazard flashers, the
multi-function switch circuit L12 from the flasher
relay circuits L60, L61, L64 and L65.
Circuit L61 feeds the left rear turn signal lamp.
Circuit L60 feeds the right rear turn signal lamp.
Circuit L65 feeds the left front turn signal lamp, side
marker lamp and the instrument cluster indicator
lamp. Circuit L64 feeds the right front turn signal
lamp, side marker lamp and the instrument cluster
indicator lamp.
Circuit Z1 provides ground for the hazard flasher
lamps.
