TURN SIGNAL SWITCH AND CIRCUIT LY-1
The turn signal circuit used on the Imperial
models consists of a manual canceling switch,
an automatic canceling switch, a flasher unit,
a relay and the necessary connecting wires and
lamps.
The manual canceling switch is of the "rock-
er button" or "teeter" type, with the letter "R"
at the top for a right turn, and the letter "L"
at the bottom for a left turn. It is located at
the bottom of the row of push buttons for
the Torque-Flite transmission. To operate the
switch, merely push the "R" or "L" end of
the rocker button. If an error has been made
and you wish to turn the signal off, merely
press the center of the rocker button and the
signal becomes inoperative.
The automatic canceling switch is mounted
on the steering column, and automatically can-
cels the signal when the steering wheel returns
to the straight-ahead position.
The flasher unit is mounted on the back of
the speedometer, behind the instrument panel.
The relay is mounted at the top of the left
cowl side panel. It contains the latching relays
which hold the circuits closed until they are
broken either by the automatic or manual can-
celing switches.

to-Lite, and Jubilee. The horn circuits are

tested in the same manner for all three makes.
The tone adjustment however, is different for
each type. The horn relay is electrically con-
nected to ignition switch and does not operate
when switch is in "OFF" position.

TESTING HORN CIRCUITS
When horns fail to blow, test circuit as follows.
Touch jumper wire from Relay "SW" terminal
to ground. If horn blows, it is an indication
that trouble is in wire from "SW" terminal
to horn button, or in horn button contact ring.
If horns do not blow, connect jumper from "B"
terminal to "H" terminal. If horns operate,
relay is defective. If horns do not blow, trouble
is in wire to horns, in horns, or in the wire
from starter relay to horn relay "B" terminal.
