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

GENERAL DESCRIPTION-CHEVROLET

The front bumper is a new, full width, three-piece

design consisting of a center and two end face bars.

Two holes are pierced in the center face bar for the

parking lamps. The bumper attaching brackets are

lengthened to attach in common with new front bumper

diagonal braces.

The rear bumper is a new three-piece design similar
in general appearance to the 1966 design. Caprice mod-

els have pierced holes in the center portion of the bumper

for the back-up lamps with the other models incorporat-

ing the back-up, lamps with the tail lamps. The fuel tank

filler door assembly remains the same as the 1966

models.

NOTE: To service the Automatic Level Con-

trol it will be necessary to secure Gauge Set

J-22124 or make up the following test gauge. If

the connectors indicated are not readily avail-

able others may be substituted.

1.
Collect the following parts:

a. Fill Valve, J-21999.

b.
A tee which has three 1/8M female taper pipe

threads.

c. An adapter which has a 1/4" female taper pipe

thread on one end and a 1/8" male taper pipe

thread on the other end.

d. Air Pressure Gauge, J-4872.

e. Two metal sleeves, rubber seals and tube nuts.

f. A length of 1/8" tubing. ~

g. Two male connectors which have a 1/8" male

taper pipe thread on one end and a 3/8-24 straight

thread male fitting on the other end.

2.
Assembly

a. Connect Fill Valve, J-21999, (female end) at male

connector 3/8-24 straight thread fitting.

b.
Connect other end of male connector to tee.

c. Connect adapter to tee.

d. Connect pressure regulator to adapter.

e. Connect second male connector to tee, (1/8 inch

male pipe thread fitting).

f. Install tubing to connector; other end of tubing

will go on unit to be checked.

NOTE:
Make certain all fittings are air tight.

Compressor Output Test—On Car

1.
With all accessories off, run the engine until fast idle

screw is off the fast idle cam. Turn off ignition.

2.
Deflate system through service valve, then remove

high pressure line at regulator adapter and connect

test gauge.

3.
Inflate reservoir to 70 psi through service valve.

4.
Observe test gauge for evidence of compressor air

leak.

5.
If leaking, proceed to leak test-compressor reser-

voir, and regulator. If not leaking, continue this

test.

6. With engine running at slow idle, observe reservoir

build-up for five minutes. Reservoir pressure should

build up to a minimum of 90 psi.

7.
If compressor fails to cycle, make sure the vacuum

and air intake lines are open and unobstructed before

removing compressor for repair.

8. If build-up is too slow, proceed to repair com-

pressor.

9. Satisfactory build-up indicates system problem to be

in the control section. However, again observe the

test gauge for evidence of an air leak and proceed

accordingly.

Regulator Test and Adjustment

Performance test the regulator with a known good com-

pressor on the car. *
