cedure in reverse order. Always lubricate all guide rails

and rollers when regulator is disassembled. Test regula-

tor thoroughly before installing door trim panel. Adjust

window as outlined in this section.

WINDOW REGULATOR-POWER

In cases where window will not operate, check electri-

cal connections first. Figure 44 illustrates lpcation of

junctions, switches and circuit breaker.

Removal

Perform operations 1 thru 5 under Window Regulator-

Manual Removal. Note, however, that electrical connec-

tors must be removed from motor before performing

any operation on regulator. Figure 44 illustrates in-

stallation of regulator on door and regulator wiring.

Disassembly

NOTE:
Do not attempt to remove motor from

regulator until the following operations are per-

formed. THIS IS A SAFETY ITEM; arm is

spring-loaded and may cause injury if not locked

in position when motor is removed.

Refer to Figure 45.

1.
Place regulator assembly in vise.

2.
Using jumper leads to 12 volt power supply, operate

motor until semi-circular hole in sector gear cen-

ters over one of two weld nuts on mounting plate.

3.
Screw a l/4"-20 x 1" bolt into weld nut so that end

passes through hole in sector gear. It may be neces-

sary to enlarge hole in gear slightly with file or

drill. Install nut on bolt to lock arm in position.

Installation

Be sure lock bolt has been removed if regulator

has been disassembled.

2.
Install lubricated regulator assembly and guide rails

in door in reverse order of removal.

3.

3.
If entire door is to be removed and door has elec-

tric power window, disconnect and remove wiring

between hinge pillar and door.

4.
If hinge is to be replaced in same position, scribe

around inner strap on door panel and record number

of shims found between hinge strap and door panel.

5. Remove bolts retaining hinge to door; do no allow

door to hang unsupported on one hinge.

6. Remove cowl panel inner trim as explained under

Front End-Cowl Area and Console Trim-.

CAUTION: Use extreme care

eral times to blow out any material dislodged

7. Install spark plugs with new gaskets and torque to

specifications.

NOTE:
The following are some of the

greatest causes of unsatisfactory spark plug

performance.

•
Installation of plugs with insufficient torque to

fully seat the gasket.

•
Installation of the plugs using excessive torque

which changes gap settings.

•
Installation of plugs on dirty gasket seal.

•
Installation of plugs into corroded spark plug hole

threads.

8^ Connect spark plug wiring.

Service
Ignition System

1.
Remove distributor cap, clean cap and inspect for

cracks, carbon tracks and burned or corroded ter-

minals. Replace cap where necessary.

2.
Clean rotor and inspect for damage or deterioration.

Replace rotor where necessary.

3.
Replace brittle, oil soaked or damaged spark plug

wires.
Install all wires to proper spark plug. Proper

positioning of spark plug wires in supports is impor-

tant to prevent cross-firing.

4.
Tighten all ignition system connections.

5. Replace or repair any wires that are frayed, loose or

damaged.

Magnetic

Distributor

There are no moving parts in the ignition pulse ampli-

fier, and the distributor shaft and bushings have perma-

nent type lubrication, therefore no periodic maintenance

is required for the magnetic pulse ignition system. Refer

to Section 6Y for an analysis of problems and/or repair

procedures encountered on the Transistorized (Magnetic

Pulse) ignition system.

1.
Check the distributor centrifugal advance mechanism

by turning the distributor rotor in a clockwise direc-

tion as far as possible, then releasing the rotor to

see if the springs return it to its retarded position.

If the rotor does not return readily, the distributor

must be disassembled and the cause of the trouble

corrected.

2.
Check to see that the vacuum spark control operates

freely by turning the movable breaker plate counter-

clockwise to see if the spring returns to its retarded

position. Any stiffness in the operation of the spark

control will affect the ignition timing. Correct any

interference or binding condition noted.

3.
Examine distributor points and clean or replace if

riecessary.

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
