Maintenance Procedure

A
periodic inspection should be made of the start­ ing circuit. Since the interval
between
these
checks

will
vary according to the type of service, it should, under normal conditions, be made every 500 hours
of operation. Inspect all starting circuit wiring for damage.
Check
for
loose
or corroded terminals and
for dependable operation of the starting motor.

H-94.
Wiring

Refer
to Fig. H-39. Inspect the starting circuit to make sure that all
connections are clean and tight.
Check
for worn or damaged insulation on the wires. Perform a volt­

age-loss
test
to make sure there is no
loss
of start­ ing motor efficiency resulting from high resistance
connections. Voltage
loss
from the battery ter­
minal
to the starting motor terminal should not
exceed .30 volts for each 100 amperes. Voltage
loss
between
the battery ground
post
and the start­ing motor frame should not exceed .10 volts for
each 100 amperes. If the
voltage
loss
is greater
than
these
limits, measure the
voltage
loss
over
each part of the circuit until the resistance causing the
voltage
loss
is located and corrected.

H-95.
Commutator
Sluggish starting motor operation may be caused by a dirty commutator or worn brushes. The com­mutator cannot be cleaned while the. starting motor is mounted on the
engine
and it
will
be necessary
to remove it and proceed as for an overhaul. Should 7— Ignition Switch

the commuator be rough or worn, it should be
removed for cleaning and reconditioning.
H-96.
Overhaul Procedure

At
periodic intervals the starting motor circuit
should be thoroughly checked and the motor re­ moved from the
engine
for cleaning and checking.

H-97.
Removal and Disassembly

Refer
to Fig. H-40 and H-41.
To
remove the starting motor from the engine, dis­
connect the leads and cover the battery lead ter­

minal
with a piece of
hose
or tape to prevent short

circuiting.
Remove the flange
bolts
holding the starting motor to the flywheel housing. Remove
the starting motor from the vehicle.

Each
part of the starting motor should be removed, cleaned, and inspected for evidence of wear or
damage. The Bendix
Folo-Thru
Drive should be
cleaned and inspected for evidence of wear or a distorted spring. Bearings should be checked for
proper clearance and fit. All insulation should be
free of oil and in
good
condition. The armature,
field coils, and brushes should be checked for
good
ground and lack of open circuits.

H-98.
Brushes

a.
The brushes should slide freely in their holders
and
make full contact on the commutator. Worn
brushes should be replaced.
b.
Check

•
Refer to
Figs.
H-44 and H-45.

Should
a starting motor
fail
to deliver maximum power the fault may be due to
voltage

switch should be replaced.
Current
model starting switches are of the
solenoid type, mounted directly on the starting
motors.
This
type switch is energized by turning
the ignition key to the extreme right position.

Should
a solenoid switch
fail
in service it is neces­

sary
to install a new solenoid assembly,

STARTING MOTOR
—
DELCO
DAUNTLESS
V-6
ENGINE

Refer
to Fig. H-45.

The
starting motor used on the Dauntless V-6 en­

gine
has an integral solenoid switch and enclosed
shift lever which first shifts the overrunning clutch
pinion into
engagement
with the ring gear on the
flywheel of the
engine
and then
closes
the electrical
circuit
to cause
engine
cranking. When the
engine

starts,
the overrunning clutch
disengages
to pre­ vent transfer of
engine
speed to the starting motor.

Note:
Should a service replacement starter motor
be required the factory recommends replacement

with
original equipment parts; however, should the need arise an existing starter motor (Delco or
Prestolite) could be replaced with the current
Delco-Remy
starter, model 1108375, with the
following modifications to the wiring harness. If
the existing starter motor wiring harness
does
not
provide a 12 ga. purple conduit wire, (connects the ignition switch to the starter motor) then a 12 ga.

purple
conduit wire 70 inches long, must be in­

stalled.
Should the existing starter motor wiring
harness
contain a 16 ga. light blue conduit wire, (connects the ignition switch and starter motor)
bend this wire back and tape out of the way.

H-109.
Starting Motor Disassembly
a.
Before removing the starting motor from the
engine, disconnect leads and cover battery lead

terminal
with piece of
hose
or tape to prevent
short circuiting.
Note
locations of wiring connec­
tions to assure proper reconnection. Remove the cap screw that secures the starting motor to the
angle bracket on the side of the engine. Remove
the two cap screws that secure the drive end of
the starting motor to the cylinder block; remove
the starting motor.

b.
Remove terminal nut and disconnect field lead,

Cleaning and
Inspection

a.
Wipe all parts clean with clean cloths. The
arma­
ture,
field coils, and drive assembly must not be
cleaned by any degreasing or high temperature
method.
This
might damage insulation so that a
short
circuit
or ground would subsequently develop.
It
would also remove lubricant originally packed

in
the overrunning clutch so that clutch would

soon
be ruined.

b.
Carefully
inspect all parts visually for wear or
damage. Make necessary repairs or replace unserv­
iceable parts. Any soldering must be
done
with

rosin
flux.

Note:
Never use acid flux when solding any elec­

trical
connections and never use emery cloth to
clean
armature
commutator or other
electrical
units. 208

Note:
Pinion clearance cannot be adjusted. If
clearance is not correct, motor must be disassem­
bled and checked for the above mentioned defects.

Any
defective parts must be replaced.
H-118. Starting Motor Test —
Genera!

To
obtain
full
performance data on a starting motor, or to determine the cause of abnormal
operation, the motor should be submitted to no-
load and locked armature
tests,
with equipment designed for such
tests.
A high-current variable resistance is required to obtain the specified volt­
age at the starting motor.
This
is necessary since
a
small variation in the
voltage
will
produce a
marked
difference in the current
drawn.

H-119.
Starting Motor No-Load Test

This
test
requires a DC voltmeter capable of
read­

ing
voltages
in a 12-volt
circuit,
a DC ammeter

with
maximum range of several hundred amperes,
a
high-current variable resistance, an rpm. in­

dicator,
and a fully-charged, 12-volt battery.

a.
Connect a jumper lead
between
S terminal
and
large battery terminal of starter solenoid.
Con­
nect voltmeter
between
either of
these
terminals (positive) and motor frame (negative, ground).

Connect
ammeter and variable resistance in series

between
positive terminal of battery and battery

terminal
of solenoid. Set up rpm. indicator to show starting motor speed.
b.
Initially,
adjust variable resistance to a value of
approximately .25 ohm. To complete the
circuit,

connect negative terminal of battery to motor

frame.
Adjust variable resistance to obtain a volt­ meter reading of 10.6 volts;
note
speed of starting motor and ammeter reading. Motor speed should
be
6750
to
10,500
rpm.; ammeter reading should
be 50 to 80 amperes.
c. Rated speed and current indicate normal condi­
tion of the starting motor. Low speed and high
cur­
rent
may show friction; this could be caused by
tight, dirty, or worn bearings, bent armature shaft,

or
a
loose
field
pole
shoe
dragging against the

armature.
It could also be caused by a short-cir­ cuited armature, or by grounded armature or field
coils.

d.
Failure
to operate and high current indicates

a
direct short circuit to ground at either the battery

terminal
or field coils.
e.
Failure
to operate and no current are usually
caused by broken brush springs, worn brushes, high insulation
between
commutator
bars,
or
some
other
condition preventing
good
contact
between
the brushes and commutator. It can also be caused by
open circuit in either the field coils or armature coils.
f. Low speed and low current show high resistance due to poor connections, defective leads, dirty com­
mutator, or one of the conditions mentioned in e,
above.
g. High speed and high current indicates a short
circuit
in the field coils. H-120-
Locked
Armature Test

This
test
requires a DC voltmeter with range ap­

propriate
to read
voltages
in a 12-volt
circuit,
a DC
ammeter with maximum range of several hundred
amperes, a high-current variable resistance, a
clamping fixture to lock
together
the motor shaft

and
case, and a fully-charged 12-volt battery.

a.
Connect a jumper lead
between
S terminal and
large battery terminal of starter solenoid. Connect
voltmeter
between
either of
these
terminals (posi­
tive) and motor frame (negative, ground). Connect
ammeter and variable resistance in series
between
positive terminal of battery and battery terminal
of solenoid.
Install
clamping fixture to lock motor
shaft and case
together
securely.
b.
Initially,
adjust variable resistance to approxi­
mately .05 ohm. To complete the
circuit,
connect
negative terminal of battery to motor frame. Ad­

just
variable resistance to obtain a voltmeter
read­
ing of 4.0 volts. Ammeter reading should be 280
to 320 amperes.

H-121.
Solenoid Starter Switch — Delco

The
solenoid-type switch is mounted directly on
the starting motor.
This
type of switch is energized
by turning the ignition key to the extreme right position. Should the solenoid switch
fail
in service

it
is necessary to install a new assembly.

Should
a starting motor
fail
to deliver maximum power the fault may be due to
voltage
drop at the

starter
switch contacts due to corrosion or burning.

Check
the switch by comparing the
voltage
at the
battery across the terminals. The
voltage
drop
should not exceed .05 volts per 100 amperes.
In
order to remove the starter solenoid, it is neces­

sary
to remove the starter assembly.

ELECTRICAL
INSTRUMENTS

H-123.
Fuel
Gauge —
CJ-3B

The
fuel
gauge
circuit is composed of the indicating

unit,
mounted on the instrument panel, and the
fuel tank unit, connected by a single wire through the ignition switch.

Should
the
gauge
fail
to register, check all wire con­ nections to be sure they are tight and clean; also
be sure both units are well grounded. If, after this
check, the
gauge
does
not indicate properly, remove
the wire from the tank unit and connect it to a
new tank unit which must be grounded to the tank

or
frame for
test.
Turn
the ignition switch "ON"
and
move
the float arm through its range of travel,
watching the dash unit to determine if it indicates
correctly.
If it fails to do so the trouble is probably

in
the dash unit and it should be replaced.

Should
a new tank unit be unavailable for this
test,
disconnect tank unit wire at the instrument panel

gauge.
Connect one lead of a 12 V, 1 CP
test
light
to the instrument panel unit terminal and with the
ignition switch
"ON"
ground the other lead. If the
unit is operating correctly the pointer
will
move

approximately three-quarter across the
dial.
Do not attempt to repair either unit; replacement
is the only precedure. 211

H

ELECTRICAL
SYSTEM
H-124. Testing Indicators and Gauges

Two
gauges
(fuel and temperature) and two in­ dicators (oil pressure and battery charge) that are
located in the instrument cluster are electrically operated.

The
fuel
gauge
is connected by a single wire to a
float-and-slide-rheostat sending unit in the fuel
tank.

The
temperature
gauge
is connected by a single

wire
to a resistance-type sending unit mounted on the engine.

The
battery charge indicator operates when there
is a difference in potential
between
the generator
and
the battery
.The
battery charge indicator lights
when the generator is not charging the battery. The
indicator
light
goes
out when the generator
begins

to charge the battery.

The
oil pressure indicator is connected by a single

wire
to a diaphragm switch located on the engine.
When
engine
oil pressure is low or zero and the
ignition switch is on, the oil pressure indicator
will

light. When
engine
speed is increased slightly above idle speed, raising the oil pressure to approximately 6 psi. [0,2 kg-cm2], the diaphragm switch
will
open the circuit and the indicator light
will
go out.

A
voltage
regulator maintains a constant
voltage
to the
gauges
in normal operation. On early vehicles,
this
voltage
regulator was mounted on the
rear
of
the instrument cluster. On current vehicles, the
voltage
regulator is integral with the fuel
gauge.

Should
trouble
develop
in the
gauges,
first check the regulator (fuel
gauge
on current production vehicle). If the
voltage
to the regulator is below 10 volts system low
gauge
readings
will
result.
Voltage in
excess
of 16 volts
will
not affect
gauge

readings but may result in premature wear of the
regulator contacts. If the
voltage
to the regulator is

within
the above limits, check the electrical con­ nections to the regulator (or fuel gauge), especially
the ground connection. If the readings of all the
gauges
is too high, or they all read too low, replace
the regulator (or fuel gauge).

If
the temperature
gauge
or heat indicator in the
instrument cluster have failed, the cause may
originate from the jumper bar shorting out against the instrument case.
Check
the jumper bar
between

the temperature
gauge
and heat indicator at the

rear
of the instrument case. On later production vehicles, the jumper bar is covered with an in­
sulating
sleeve
to protect it from shorting out
against the instrument case. If the jumper bar

does
not have this
sleeve,
either install one or

wrap
the bar with plastic electrical tape to
half

an
inch [12,7 mm.] from each end. When installing the jumper bar, be sure the curved
segment
is
closest to the fuel
gauge.

Should
only one of the two
gauges
register incor­
rectly,
check the lead wire from the
gauge
to the
sending unit for shorts or open connections. Next disconnect the
gauge
from the sending unit, and
connect the
gauge
to a new fuel tank sending unit

which
has been grounded to the vehicle.
If
the
gauge
registers incorrectly when operating the new unit,
replace the
gauge;
if correctly, replace the sending

unit.

Should
a new fuel tank unit not be available for testing, use a 12-volt
test
light in its place. When
the
gauge
is operating correctly, the pointer
will

move
approximately three-quarters across the
dial.

On
some
vehicles, the temperature
gauge
may
register on or
close
to the H (hot)
mark
when
coolant temperature is
190°F.
to
200°F.
[88°C.
a

93°C.].
In such cases, a 25-ohm,
1-watt
resistor
may be installed on the temperature
gauge
which

will
place the pointer just beyond the center
mark
at a coolant temperature of
190°F.
to
200°F.
Install

the resistor
between
the two terminals on the back
of the
gauge.
Insulate the
exposed
leads of the resistor with electrical tape.

If
the oil pressure indicator
does
not indicate cor­

rectly,
first check the light bulb. Next check all
connections and lead wires. If, after all possible

defects
are corrected, the indicator light
does
not go on and off properly, then the diaphragm type
switch in the cylinder block should be replaced.

H-12S.
LIGHTING SYSTEM The
wiring of the lighting systems is shown in
the wiring diagrams, which indicate the various units in relation to their positions in the vehicle.
The
wires in the various circuits are of different
colors or are marked by tracers to aid when check­
ing individual circuits.

The
lighting circuits of all models are protected by

an
overload circuit breaker mounted on the back of the main light switch and no replaceable fuse is
required.

The
upper and lower headlight beams are con­
trolled by a
foot
switch located on the toe board
to the left of the clutch pedal.
H-126.
Main
Light
Switch

This
switch is a dual functioning unit having two

push-pull
positions and a rotary action. When
pulled out to the first position, the front parking
and
tail
lights are turned on. When pulled all the
way out to the second position, the headlights and
tail
lights are turned on. Rotating the switch to
the right dims the instrument cluster lighting.

The
switch may be removed from the instrument
panel by first loosening the set screw in the control
knob and removing the knob. The retaining nut may then be removed and the switch removed
through the
rear
of the instrument panel.

Windshield Wiper System

Early
production vehicles equipped with
the
Dauntless V-6
engine
have
two
single speed wind­
shield wiper motors mounted above
the
windshield inside
the
vehicle. The wiper motors
are
operated

and
controlled
by a
switch located
on the
instru­
ment panel.

Current
production vehicles with stationary wind­
shield have
a
two-speed
electric windshield wiper motor mounted below
the
windshield outside
the

vehicle on the driver's side. The wiper motor switch is located
on the
instrument panel
to the
left
of

the steering column.

H-142.
Two-Speed Wiper Motor

The
two-speed
electric wiper motor
is
operated and
controlled
by a
turn
type, three poled, dash switch,
containing
a 6
amp. circuit breaker.
Current
flow
is directed from
the
battery through
the
ignition
switch
to the
wiper dash switch assembly
to the

two-speed
wiper motor, which passes current from the designated motor brush (high,
low or
park)
to

the armature circuit
to
ground.

Troubleshooting Procedure
Troubleshooting procedures
are
divided into
two

categories: wiper troubleshooting
in
vehicle; wiper
