ing bolts from crushing in the fender mounting

flange.

If shimming is done without the fenders being disas-
asembled, it is suggested that fender mounting bolts

rearward of radiator support be loosened while shims

are inserted and sheet metal fit is checked. Tighten

shimmed mounting bolts first, then all others.

GENERAL DESCRIPTION

.
The lighting system includes: the main lighting switch,

stop light, dimmer, and backing lamp switches, head-

lamps, parking lamps, stop, tail and directional lamps,

instrument illumination and indicator lamps, and the

necessary wiring to complete the various circuits. A

fuse panel provides convenient power take offs and fuse

clips for the appropriate circuits (fig. 1).

Chevrolet and Chevelle headlamp installation is all

new in that the headlamps are located in the radiator

support with adjusting screws and springs. Eliminating

the need for having separate headlamp housings. Chev-

rolet and Chevelle headlamp retainers and springs are

interchangeable.

Chevy n headlamp housings are new because of revised

front end styling and Corvette front end lighting is basi-

cally carryover.

Front fender lamps have been added as an option for

Chevrolet models and as standard equipment on Caprice

series.

Camaro models use single headlamps and the Rally

Sport model headlamps are covered by a retractable

section of the grille when lamps are not used. The sec-

tion of the grille covering the headlamps folds back when

lights are required; the headlamps are stationary. The

covering is retracted by a small electric motor mounted

to the headlamp housing. The headlamps are automat-

ically uncovered when the headlight switch is pulled "ON"

for illumination. If at any time the electrical circuit

becomes inoperative, the lamps can be uncovered manu-

ally. The ignition switch must be
"ON"
in order to close

the headlamp doors.

Parking lamp for Chevelle and Chevrolet models are
new due to revised front end sheet metal and bumper

styling. Parking lamps are located in the bumper on

Chevrolet, Chevelle and Chevy n models

Camaro parking lamps are located in the radiator

grille except for the Rally Sport models on which the

parking lamps are in the valance panel. For styling

reasons, the lens is white and an amber glass bulb is

used. All Camaro parking lamps require a separate

ground wire to assure a good ground contact because of

the plastic grille and painted contact surfaces.

The Chevrolet tail, stop, and directional lamps are in

one housing with a three section lens design on Impala

and Caprice sedans. The center lens for Impala series

is the back-up lamp. The center lens on the Caprice is

a tail lamp with the back-up lamps being located in the

rear bumper. Chevrolet station wagons have three indi-

vidual housings with three lenses, the center lamp being

the back-up. Biscayne and Bel-Air sedans have a single

housing and lens for tail, stop, and directional lamp with

a similarly constructed back-up lamp inboard and adja-

cent to it.

Chevelle tail, stop, and directional lamps are a single

lens design that follows through with the rear fender

styling. The back-up lamp is located in r.ear bumper.

Camaro models except Rally Sport have tail lamps

with integral back-up lamps mounted inboard of the rear

fenders between the trunk opening and bumper. The

Rally Sport model has dual tail lamps in the rear housing

and valance mounted back-up lamps.

Corvette, Chevy n, and Corvair tail and directional

signal lights are carryover. The Corvette has new back-

up lamps center mounted above the license plate opening.

FJg.
1 - Fuse Panel Assembly

All power window and tailgate circuits require the igni-

tion switch to be "ON" to open or close the windows un-

like past model designs which were operated independ-

ently of the ignition switch.

The windshield wiper and washer switch is new in that

washer button in the center of the knob has been deleted
and its function will be accomplished by pushing the knob.

A set screw is used to retain the knob to the shaft.

In addition to fuses, the wiring harness incorporates

fusible links to protect the wiring. Links are used rather

than a fuse in wiring circuits that are not normally fused,

such as the ignition circuit. Fusible links in the Chevro-

let wiring are four gauge sizes smaller than the cable it

is designed to protect. The links are marked on the

insulation with wire gauge size because of the heavy insu-

lation which makes the link appear a heavier gauge than it

actually is.

Engine compartment wiring harness incorporate sev-

eral fusible links. Each link is identified with its gauge

size.
A fusible link is a length of special wire (normally

four wire gauges smaller than the circuit it is protecting)

used in wiring circuits that are not normally fused, such

as the ignition circuit. The same size wire with a spe-

cial hypalon insulation must be used when replacing a

fusible link.

The links are:

1.
The pigtail lead at the battery positive cable (except

Corvette) is a 14 gauge, brown fusible link protecting

the 10 gange battery charging circuit. This wire is

an integral part of the battery cable assembly and

servicing requires replacing the complete battery

cable assembly. On Corvette models this link is

installed as a molded splice at the solenoid "Bat"

terminal and servicing requires splicing in a new

link.

2.
A 16 gauge black fusible link is located at horn relay

to protect all unfused wiring of 12 gauge or larger.

It is a serviceable piece with an in-line connector

and is not integral with the wiring harness.

3.
The generator warning light and field circuitry (16

gauge wire) is protected by a fusible link (20 gauge

orange wire) used in the "battery feed to voltage

regulator #3 terminal" wire. The link is installed

as a molded splice in the generator and forward lamp

harness and is serviced by splicing in a new 20 gauge

wire as required.

4.
The ammeter circuit on all models is protected by

two orange, 20 gauge wire fusible links installed as

molded splices in the circuit at the junction block or

the solenoid "Bat" terminal (Corvette only) and at the

horn relay. Each link is serviced by splicing in a

new 20 gauge wire as required.

The wiring harnesses use a standarized. color code

common to all Chevrolet vehicles. Under the color code,

the color of the wire designates a particular circuit. The

harness title indicates the type of harness, single of mul-

tiple wire, and also describe the location of the harness.

The body harness is a flat, solid wire assembly and is

routed through the vehicle near the center of the body.

Composite wiring diagrams (figs. 104 thru 124) are in-

cluded at the end of this section.

MAINTENANCE AND ADJUSTMENTS

Maintenance of the lighting units and wiring system

consists of an occasional check to see that all wiring

connections are tight and clean, that the lighting units are

tightly mounted to provide good ground and that the head-

lamps are properly adjusted. Loose or corroded con-

nections may cause a discharged battery, difficult start-

ing, dim lights, and possible damage to generator and

regulator. Wire harnesses must be replaced if insulation

becomes burned, cracked, or deteriorated. Whenever it
is necessary to splice a wire or repair one that is bro-

ken, always use solder to bond the splice. Always use

rosin flux solder on electrical connections. Use insulat-

ing tape to cover all splices or bare wires.

When replacing wires, it is important that the correct

size be used. Never replace a wire with one of a smaller

size.

Each harness and wire must be held securely in place

by clips or other holding devices to prevent chafing or

wearing away the insulation due to vibration.

By referring to the wiring diagrams, circuits may be

tested for continuous circuit or shorts with a conventional

test lamp or low reading volt meter.

HEADLAMP ADJUSTMENT-

T-3 HEADLAMPS

CAUTION: Check and tighten radiator support

grille retaining bolts prior to attempting head-

lamp aiming. Distorted grille or supports in

this area will hinder proper aiming of head-

lamps. On Corvette models make sure head-

lamp panel is adjusted properly - refer to

"Headlamp Panel Travel Adjustment".

When aiming headlamps, vehicle should be filled to ca-

pacity with gas, oil, and water but no load. Tires should

be uniformly inflated to recommended pressure.

the T-3 Safety Aimer-Type B (fig. 2), is used for the

headlamp aiming description that follows. An adapter is

required with the Type B T-3 Aimer when adjusting the 7

inch headlamp used on the Chevy n vehicle.

1.
Drive vehicle onto selected aiming area. Bounce

vehicle several times and allow to settle.

2.
Remove headlamp bezels.

3.
Mount the T-3 Aimers on either the No. 1 or No. 2

pair of headlamps so that "the points of the headlamps

engage the smooth inner ring of the aimers.
