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.
g. Be sure the

Aiming Head Lamps
a.
Turn
the headlights on low beam. Cover the lamp not being aimed. Be sure to use the horizontal reference line on the screen that is the same dimen
sion as the vehicle lamp height.
b.
Turn
the vertical aiming screw counterclock
wise until the lamp beam is considerably lower
than
the horizontal reference line on the screen.
Then,
turn
the screw clockwise until the top
edge
of the high intensity
area
is even with the horizontal
line.
See Fig. H-60.

Note:
Always bring the beam into final position
by turning both aiming screws clockwise so that
the unit is held under proper tension when the operation is complete.
c. Turn

wise until the beam is off.
Then,
turn
the same
screw
clockwise until the
left
edge
of the high
intensity area is 2" [5,08 cm.] to the right of the
lamp center line. See Fig. H-60.
d.
Cover the lamp that has been aimed and aim
the other lamp using the same procedure.
e.
Carefully
reinstall the head lamp doors.

Parking
and
Turn Signal Light
The
parking lights are mounted in the radiator
guard
panel just below the headlights. These lights
are
on only when the main switch control knob is
pulled
out to the first notch.
To
replace a parking lamp, remove two screws allowing the lens and colored reflector to be re
moved. Replace the lamp, which is recessed back
in
the housing.
If
the
complete
parking light assembly is to be
removed for service or replacement, disconnect the
wire
plug at the back of the housing.
Then
remove
the nuts and lock washers securing the parking light assembly and remove out the front of the
panel.
H-134. Tail, Stop
and
Turn Signal Light
Refer
to Fig. H-57 and H-58.
The
tail
lights are mounted in the
rear
corner
posts
of the body. They are on whenever the main switch
control
knob is pulled out to any position.
a.
To replace a lamp, remove the snap ring on
early
models
and remove the lens; on late
models
remove lens screws, lens and gasket.
Clean
lens
and
reflector before replacing.
b. To remove the parking and
tail
light housing,
disconnect wiring, remove the two nuts and lock
washers securing
tail
light assembly to body and remove from
rear
of body.
H-135-
Backup Lights •
Refer to Fig. H-61.
The
backup lights on late production vehicles are located on the
rear
of the vehicle directly below
the
tail
light. The backup lights are actuated
through a switch when the ignition is on and the
transmission
is in reverse. 215
