Engine compartment wiring harness incorporates sev-

eral fusible links. Each link is identified with its gage

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

four wire gages 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 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 gage, brown fusible link protecting

the 10 gage battery charging circuit. This wire is an

integral part of the battery cable assembly and serv-

icing 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 gage black fusible link is located at the horn
4.
relay to protect all unfused wiring of 12 gage or

larger. It is installed as a molded splice and serv-

icing requires splicing in a new link.

The generator warning light and field circuitry (16

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

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 gage

wire as required.

The ammeter circuit on all models is protected by

two orange, 20 gage 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 gage wire as required.

MAINTENANCE AND ADJUSTMENTS

At regular intervals, inspect the terminals for cor-

rosion an4 loose connections, and the wiring for frayed

insulation. Check mounting bolts for tightness. Check the

drive belt for alignment, proper tension and wear. Be-

cause of the higher inertia and load capacity of the rotor

used in A.C. generators, PROPER BELT TENSION is

more critical than on D.C. generators.

Since the Delcotron and its companion regulator are

designed for use on negative polarity systems only, the

following precautions must be observed. Failure to ob-

serve these precautions may result in serious damage to

the charging system.

1.
When installing a battery, always make absolutely

sure the ground polarity of the battery, generator and

regulator is the same.

2.
When connecting a booster battery, make certain to

connect the correct battery terminals together.

3.
When connecting a charger to the battery, connect the

correct charger leads to the battery
%
terminals.

4.
Never operate the generator on an uncontrolled open

ELECTRICAL

Any one of the following general complaints may be due

to electrical trouble in the overdrive circuit.

1.
Does not engage.

2.
Does not release.

3.
Does not kickdown from overdrive.

These troubles may be traced and remedied as de-

scribed in the following paragraphs.

1.
Does not engage

a. With the ignition switch on, ground the "KD" ter-

minal of the solenoid relay with a jumper lead.

If the solenoid clicks, the relay and solenoid cir-

cuits are in operating condition. If no click is

heard in the relay, check the fuse and replace if

defective.

b.
If the fuse is good, use a second jumper lead to

connect the "SOL" and "BAT" terminals of the

relay. If a click is now heard in the solenoid, the

relay is probably at fault and should be repaired

or replaced.

c. If the solenoid does not click in Step b, check the

wiring to the No. 4 terminal of the solenoid and

replace if necessary. If the wiring is not defec-

tive,
the trouble is probably in the solenoid. Re-

move the solenoid cover, examine the solenoid

contacts in series with the pull-in winding and

clean if necessary. Test again for clicks, as in

Step b, after replacing solenoid cover and lead

wires.
Replace the solenoid if trouble has not

been corrected.

d. If the relay and solenoid circuits are in good con-

dition as determined in Step a, leave the ignition

switch on and make sure the manual control knob

is in the overdrive position. Ground one and then

the other of the two terminals next to the stem of

the kickdown switch (identified as "SW" and
?fREL"). K the solenoid clicks when one terminal

is grounded but not the other, replace the switch.

If the solenoid does not click when either of the

terminals is grounded, check the wiring between

the relay and the kickdown switch and replace if

defective.

e. If the solenoid clicks as each terminal is grounded

in Step d, ground the governor switch terminal.

If the solenoid clicks, the governor switch may be

defective. If the solenoid does not click, check

the wiring between the kickdown and governor

switches and replace if necessary.

2.
Does not release

a. Remove the connection to the "KD" terminal of

the relay. If this release overdrive, look for a

grounded control circuit between the relay and

governor switch.

b.
If the overdrive is not released in Step a, dis-

connect the lead to the "SOL" terminal of relay.

If this releases the overdrive, replace the relay.

3.
Does not kickdown from overdrive

a. With the engine running, connect a jumper lead

between the No. 6 terminal of the solenoid and

ground. Operate the kickdown switch by hand.

This should stop the engine. If it does, the sole-

noid is probably defective and it should be checked

for dirty ground-out contacts or other defects

within the ground-out circuit of the solenoid (fig.

4B).
Clean the contacts or replace the contact

plate as required.

b.
If the engine does not stop in Step a, ground one

and then the other of the two terminals (Identified

as "IGN" and "SOL") farthest from the sfem of

the kickdown switch. The engine should stop when

one of the two terminals (IGN) is grounded. If

the engine does not stop when the terminal is

grounded, the wiring or connections to the switch

between the switch and coil are defective. When

the btlier terminal (SOL) is grounded, the engine

should stop when the kickdown switch is operated.

If the engine does not stop when the kickdown

switch is operated with the second terminal

grounded, the kickdown switch is defective. If

the trouble is in the kickdown switch, adjust the

linkage to give more travel of the switch rod.

If this does not correct the trouble, replace the

kickdown switch.

If the kickdown switch operates as it should,

check for an open circuit in the wiring between

the kickdown switch and the No. 6 terminal of the

solenoid.

c. If the trouble is not located by the above checks,

the upper contacts of the kickdown switch may not

be opening. To check for this condition, ground

the overdrive control circuit at the governor

switch. This should cause the solenoid to click.

Operate the kickdown switch by hand. This should

cause a second click as the solenoid releases.

If there is no second click, adjust the linkage to

give more travel of the switch rod. If this does

not correct the trouble, replace the kickdown

switch.

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.
