energizes
auxiliary
equipment
such as
windshield wipers, radio, and heater. The turn
signal

will
operate
with the
ignition
key in
either the

or right
position.
The
ignition
switch is held in
position
by a
tension
spring on the back
of the instrument panel and a
notched
bezel on
the front of the instrument panel.

Lighting System

The
wiring for the lighting
system
is shown in the
wiring diagrams, Figs. H-2 thru H-7 of the manual,
which indicate the various units in relation to their

position
in the vehicle. The lighting circuit is pro­
tected
by an overload circuit breaker
mounted
on the rear of the light switch.
The

given in Par. H-78, adjusting the fan belt to its
proper tension after the alternator is mounted, as described in Par. C-27. Wires should be connected
as shown in Fig. H-38.

When
the vehicle is equipped with a radio, a .55
mfd. capacitor is required on the alternator. Mount
the capacitor strap to a ground terminal and con­
nect the lead to the output terminal.

Ignition
Switch

The
ignition switch serves both to energize the
ignition system and
engage
the starter switch.
The
ignition switch has four positions: (1) AC­

CESSORY,
(2)
LOCK,
(3) ON, and (4)
START. The
key must be in the switch to turn it to any position other than
LOCK,
and the key can be
removed only in the
LOCK
position.
In "ACC",
a connection is made from the battery

terminal
to the accessory terminal of the switch to
allow accessories such as the radio, blower and/or
windshield wiper to be operated with the ignition, fuel
gauge
and indicator light circuits off.
In "LOCK",
no accessory supplied through the
ignition switch can be operated. Also, the ballast
resistor (V-6
engine
only) circuit to the ignition
coil
(IGN) is grounded.
In
"ON", a connection is made from the battery

terminal
to the accessory terminal so that all
ignition switch supplied accessories can be operated. Also the battery is connected to the ballast resistor
(V-6
engine
only) leading to the ignition coil

(IGN).
From
this same terminal, a lead
into
the
instrument cluster energizes the fuel
gauge
and
indicator lights.
In "START",
all ignition switch supplied acces­
sories are temporarily disconnected. A connection is made to the starter solenoid lead. The charge

and
oil indicator lamps
will
light until the
engine
is started.

Ignition
Switch
Removal

a.
Remove the bezel nut and pull back the main
switch body.
Lower
the switch
body
from under the instrument panel so that the wiring harness plug

can
be removed from the prong connection,
b. If the lock cylinder is to be removed, turn the
ignition key to the right and insert a short
piece

of wire or end of a paper clip
into
the lock release

hole
in the switch body. Pressing on the lock
cyl­
inder retainer
will
allow the cylinder to be removed.
H-91.
Ignition
Switch
Installation

Before installing the lock cylinder
into
the main
switch body,
note
the position of the lock cylinder
retainer.

a.
Place the lock cylinder
into
the main switch
body
with the highest part of the lock cylinder
retainer in line with the lock release
hole
in the
main
switch body.
b. Compress the lock cylinder retainer so that the
lock cylinder can be installed all the way
into
the

main
switch
body
or until the retainer can be

seen
through the pin hole.

c.
Install
wiring harness plug
onto
switch
body

prong connection.

d.
Install
this main switch
body
into
the instru­
ment panel opening from the
rear.

e. To make sure that the switch is in its correct position, install the ignition key in the off position.
Then
turn the switch
body
until the key is straight
up and down. Remove the key, install the bezel
nut and secure.

F4
ENGINE

The
Prestolite starting motor on the V6
engine
is

similar
in construction (with exception of pinion housings) to the starting motor installed on F4

engines.
The
starter solenoid switch is bolted to the starter
frame.

The
starter is equipped with
sealed-type
absorbent
bronze bearings and no lubricant is required. Service procedures for the Prestolite starter are
given in
Pars.
