unit, or reversed wiring on the dash unit. If
the dash unit needle reads low scale at all
times, check for open circuit to the sending
unit, open circuit in the sending unit, or
failure of the ignition switch circuit to
energize the gauge units.
If receiver operates correctly, check sender on
car to see if it is properly grounded. If car
is radio equipped, check condenser on sender. If
condenser is shorted, it will cause receiver to
over-indicate. When replacing condenser, it is
preferable to use one of .10 microfarad capaci-
ty, but up to .50 can be used if necessary to
cut out radio interference.
If ground and condenser are all right, replace
sender and check to see if this has corrected
the difficulty.
If receiver does not operate or fails to
operate correctly, check wire lead to receiver
and replace wire if faulty. If wiring is good,
then replace receiver and check with sender on
car. If receiver fails to operate, then replace
sender.
NOTE: If necessary to replace the receiver
because it has been burned out, check
wiring, sender, and radio condenser (if
any) for a "short" and correct this
condition. Otherwise, new receiver will
also burn out. A short in the gauge
circuit is easily recognizable because it
will cause receiver to over-indicate in
most cases beyond full scale.
WARNING: Do not apply six volts direct to
receiver (dash unit) as this will burn it
out.
IGNITION LOCK CYLINDER REMOVAL
"Hornet" and "Wasp" Series
Remove the left ash tray assembly. Then remove
the large switch retaining nut and "map" reading
light assembly. Enough slack exists in the
wiring to the ignition switch to permit lowering
the switch assembly so that the ignition lock
cylinder can he removed.
The cylinder is held in the housing by a
spring loaded horseshoe lock which snaps into a
groove cut in the switch housing to retain the
cylinder.
Insert a stiff piece of wire, or paper clip,
into the small hole as illustrated in Figure 50.
Turn the key to the right (ignition "on"
position). With the wire, depress the horseshoe
lock in the lock cylinder and pull lock cylinder
from the housing.
FIGURE 50— Ignition Switch Assembly
"Hornet" and "Wasp" Series
Briggs and Stratton type lock cylinders are
used on the "Hornet" and "Wasp" Series.
"Rambler" Series
Disconnect the ignition switch wires and
remove the switch retainer nut located behind
the instrument panel. The switch assembly may
then be withdrawn from the panel. Insert a
stiff wire, or paper clip, through the small
hole in the switch housing to depress the
small horseshoe lock retaining the lock
cylinder (Fig. 51).

"Rambler" Series
Briggs and Stratton lock cylinders are used
on all "Rambler" Series.
IGNITION SWITCH REMOVAL
Follow the procedure outlined under "Ignition
Lock Cylinder Removal."
CAUTION: Before any work is performed
under the dash, the battery should be
disconnected from the electrical sys-
tem.
CIRCUIT BREAKERS
"Hornet" and "Wasp" Series
Circuit breakers are provided to protect the
main electrical wiring from overload. These
consist of 20 ampere circuit breaker (ignition
switch, heater motors, and stop light) and one
30 ampere circuit breaker (main lighting
circuit). The 20 ampere circuit breaker is
located behind the dash panel on the left side
of the ceiling of the cowl. The 30 ampere
circuit breaker is attached to the headlight
switch.
ELECTRICAL FUSE
"Rambler" Series
A 30 ampere fuse is provided in the light
switch assembly to protect the main lighting
circuit from overload. The stop light and
directional signal lights are protected by a
30 ampere fuse located on the left front
wheelhouse panel.
HEAD LAMPS
The head lamps are of the familiar sealed beam
type. Adjustment of beam direction may be made
to agree with existing state regulations by
the method outlined
