H-1. GENERAL
All
'Jeep' Universal vehicles are equipped with 12- volt electrical systems. Use caution around the higher
voltage
of the 12-volt system as accidental
short
circuits are more capable of damaging electri
cal
units. Also, arcs around the 12-volt battery are
more apt to ignite any gas that may be escaping
from
it. In the following paragraphs
will
be found
information about the battery, distributor, coil,
generator, alternator,
voltage
regulator and start ing motor. These units with the connecting wires,
make
up the
engine
electrical system. The wiring
diagram
will
show the different circuits of the en
gine
electrical system and the various units which
make
up
those
circuits.
With
plastic-covered wiring harnesses use only
rubber-insulated
wiring clips.
Caution:
All current production vehicles are 12- volt, negative ground. Whenever servicing a 12-
volt electrical system, use caution, as an accidental
short
circuit is capable of damaging electrical units. Disconnect battery ground cable before changing
electrical
components.
H-2.
Battery
The
battery is a storage reservoir for electrical
energy produced by the alternator or generator.
The
battery should store sufficient energy for
operation of the entire electrical system when the
alternator
or generator is not pr 1,scing output,
such
as when the ignition is first turned on. Of
particular
importance is maintaining the electrolyte
at the correct level, regularly checking with a
hydrometer, and maintaining clean, tight cable connections.
Battery
service information is given in this section.
Caution:
Do not allow flames or sparks to be
brought near the vent
openings
of the battery since
hydrogen gas may be present in the battery and might explode.
Note:
The liquid in the battery (electrolyte) is a
solution of sulphuric acid which, on contact, can
injure
skin or
eyes,
or damage clothes. If it is spilled
on the skin or spattered in the
eyes,
promptly flush
it
away with quantities of clear water only. If the
acid
is spilled on clothes, wet it thoroughly with a
weak
solution of ammonia, or with a solution of sodium bicarbonate or baking soda.

Caution:
When installing the battery, the nega
tive terminal must be grounded. Reverse polarity of the battery can cause severe damage to the charging system.
Battery
Inspection
a.
Check
the specific gravity of the electrolyte in
each cell of the battery. A hydrometer reading of 1.260 indicates that the battery is fully charged.
If
the reading is 1.225 or below, the battery
needs
recharging.
If one or more cells is 25 "points" (.025) or more lower than the other cells, this in
dicates that the cell is shorted, the cell is about to
fail,
or there is a
crack
in the battery partition in
the case. Unless the battery is repaired or replaced, battery trouble
will
soon
be experienced.
b.
Check
the electrolyte level in each cell, add
distilled
water to maintain the solution [9,5 mm.] above the plates. Avoid overfilling. Replace
the filler caps and tighten securely. It is important to keep the electrolyte level above the plates at all
times because plates that are
exposed
for any
length of time
will
be seriously damaged.
c.
Check
the wing nuts on the hold-down frame for tightness. Tighten them only with finger pres
sure,
never with pliers or a wrench. Excessive
pressure
could damage the battery case.
d.
Clean
the battery terminals and cable con nectors. Prepare a strong solution of baking soda
and
water and brush it around the terminals to
remove any corrosion that is present. The cell caps must be tight and their vents sealed to prevent
cleaning solution entering the cells. After cleaning,
connect cables to battery and coat the terminals
with
heavy grease.
e.
Inspect the battery cables and replace if badly
corroded
or frayed.
Check
tightness
of terminal
screws to ensure
good
electrical connections.
Check
the
tightness
of the negative ground cable connection at the frame to ensure a
good
ground
connection.
f.
Load
test
the battery. Connect a voltmeter across the battery. Run the starting motor for 15 seconds. If the
voltage
does
not drop below 10
volts the battery is satisfactory. If the
voltage
falls
below the figure given, yet the specific gravity is
above
1.225,
the condition of the battery is questionable.

Hazard
Warning Lights
All
current production vehicles
are
equipped with
a
four-way flasher warning system.
The
control switch
is
located
on the
instrument panel left
of
the steering column.
With
the
switch pulled
out,
the
two

on
current
production vehicles
are
mounted
on the
side
of
the front fender and
on the
side
of
the
rear

or
high speed only.
It is
important that
the
wiper
operates
at low
speed during parking cycle.
Dis
connect wiring harness from wiper motor
and try
operating wiper independently
of
dash switch.
If
wiper
shuts
off
correctly with
crank
arm
in
park
position and wiper has both speeds, check
the
lead
between
terminal
and
dash switch ground
and
check
for
defective dash switch.
If
wiper shuts
off
correctly,
but has
high speed only, check lead
be
tween wiper terminal and dash switch
for an
open
circuit
and check
for
defective dash switch.
If
still

Par. H-145.
c. Wiper
has
only fast speed.
Check
for
defective dash switch
or
open lead
between
terminal
and

H-141.
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.
H-143.
Troubleshooting Procedure
Troubleshooting procedures
are
divided into
two
categories: wiper troubleshooting
in
vehicle; wiper
troubleshooting
on
bench.
Fig. H-65 and H-66
illustrates connecting leads
of the
two-speed
wiper for either bench operation
or to run
wiper inde
pendently

wiper troubles and remedies are
as
follows
:
