GENERAL DESCRIPTION

The charging system includes the battery, generator,

regulator, telltale light, and necessary wiring to connect

these components. The Delcotron is offered as standard

equipment, although there are various capacities avail-

able on all models.

The Delcotron continuous output A.C. generator (fig.

lc) consists of two major parts, a stator and a rotor. The

stator is composed of a large number of windings as-

sembled on the inside of a laminated core that is attached

to the generator frame. The rotor revolves within the

stator on bearings located in each end frame. Two

brushes are required to carry current through the two

slip rings to the field coils wound concentric with the

shaft of the rotor. Six rectifier diodes are mounted in the

slip ring end frame and are joined to the stator windings

at three internally located terminals.

Diodes are mounted in heat sinks to provide adequate

heat dissipation. The six diodes replace the separately
mounted rectifier as used in other types of application.

The diodes change the Delcotron A.C. current to D.C.

current.

Two regulators (fig. 2c) are available on the 1967 vehi-

cles,
a double contact two unit type and a transistor

regulator. The function of these regulators in the charg-

ing system is to limit the generator voltage to a pre-set

value by controlling the generator field current. Both

regulators have an internal field relay unit. The relay

unit allows the telltale lamp to light (as a bulb check)

with the ignition key on and engine not running. When the

engine is started and the generator begins to charge, the

indicator light goes out indicating that the system is op-

erating normally.

The double contact regulator, when used with the

special 63 amp air conditioning model generator (4 ohm

field coil) uses a field discharge diode internally in the

field circuit (figs. 3c and 4c). The added diode adapts the

li the Delcotron meets the test specifications, the

problem is not in the generator.

12.
Ti the Delcotron fails to meet the test specifications,

remove it and perform bench tests and make repair

needed.

DELCOTRON DIODE AND FIELD TEST (Fig. 9c)

NOTE:
These tests will indicate good,, shorted

or open field or shorted diode but will not indi-

cate a failed open diode. If output was low and

following tests show good, refer to service op-

erations to determine cause and repair.

1.
Disconnect battery ground cable at battery.

2.
Positive diodes (Test A) connect an ohmmeter be-

tween "R" terminal and "BAT" terminal and note

Fig.
9c-Deicotron Diode and Field Test
reading, then reverse the leads at same terminals

and note this reading. Meter should read high re-

sistance in one direction and low in the other.

3.
Negative diodes (Test B) connect ohmmeter between

"R" terminal and "GRD" and note reading, then

reverse the leads and note this reading. Meter

should read high in one direction and low in the

other.

NOTE:
A high or low reading in both directions

indicates a defective diode.

4.
Open Field Check:

a. Connect an ohmmeter from "F" terminal to

"GRD"
terminal stud and note reading on the

lowest range scale. Meter should read 7 to

20 ohms.

b.
If meter reads zero or excessively high resist-

ance, the Delcotron is faulty.

5. If above tests indicate a defective Delcotron, remove

and completely check Delcotron as outlined under

''Service Operations".

INDICATOR LAMP/INITIAL FIELD

EXCITATION CIRCUIT TESTS (Fig. 10c)

On standard models the indicator lamp circuit provides

initial field excitation (causing lamp to glow). The light

is cancelled by closing the field relay which applies bat-

tery voltage to both sides of bulb (bulb goes out).

The indicator light should glow when ignition switch is

"ON"
and go out almost immediately when engine starts.

Ammeter equipped vehicles use the same initial field

excitation and control circuits as the indicator lamp ex-

cept the lamp is omitted. The continuity tests on both

type vehicles can be made as follows:

If Lamp Fails to Glow or Ammeter Fails to

Function the Possible Causes are:

1.
Faulty bulb or bulb socket.

2.
Faulty ammeter.

3.
An open circuit in wiring, regulator, or field.

4.
A shorted positive diode—(may also cause glow with

ignition switch "OFF").

TEST AS FOLLOWS:

1.
Disconnect connector from regulator and turn

ignition switch to "ON". Connect a test lamp from

connector terminal "4" to ground (fig. 10c, Step 1)

and note test lamp.

a. Lamp fails to glow—check for faulty bulb, socket

or open circuit between switch and regulator con-

nector. Repair as needed.

b.
Light goes on—failure is in regulator, Delcotron,

or wire between "F" terminals on regulator and

Delcotron. Go to Step 2.

2.
Disconnect lamp lead at ground end and connect be-

tween connector "F" and "4" terminals (fig. 10c,

Step 2), and note lamp:

a. Test Lamp glows—problem is in regulator. An

open circuit in regulator or relay is stuck dosed.

See "Service Operations" for repair.

b.
Fails to glow—problem is in wire between "F"

terminals on generator and regulator or infield

windings. Go to Step 3.

3.
Disconnect test lamp at connector "F" terminal and

connect to "F" terminal on Delcotron (fig. 10c,

Step 3), and note lamp:

a. Lamp glows-an open circuit in wire between "F"

terminals—correct as needed.

b.
Fails to glow—Delcotron field has open circuit,

see "Service Operations" to repair %

If Lamp Fails to Go Out, or if Ammeter Shows

Discharge the Possible Causes are:

1.
Loose drive belt—adjust as necessary.

2.
Faulty field relay—(see relay test and adjustment).

3.
Defective Delcotron—(see Delcotron output test).

4.
At normal idle—parallel resistance wire open (see

Resistance test). On ammeter models the initial

field excitation wire to "ACC" terminal is open.

5. Switch off—positive diode shorted (see Diode test).

FIELD CIRCUIT RESISTANCE

WIRE CHECKS

The resistance wire is an integral part of the ignition

harness. However, the resistance wire is not solderable;

it must be spliced with a crimp-type connector. It is

rated at 10 ohms, 6.25 watts minimum.

The check for an open resistor or field excitation wire

(connected to the ignition switch "ACC" terminal) is as

follows:

1.
Connect a test lamp from the wiring harness con-

nector terminal "4" to ground as shown in Figure

10c (Step 1).

2.
Turn the ignition switch to the "ON" position and

note test bulb.

a. Test lamp glows—resistance is O.K.

b.
Test lamp does not glow—the resistor is open

circuited—note also that dash lamp does not glow

during this test because series resistance of the

2 bulbs causes amperage to be too low.

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.
