MAINTENANCE

• SERVICE INFORMATION
All vehicles are equipped with a maintenance-free
(MF) battery when shipped from the factory (Fig. 10).
A maintenance-free battery does not have removable
cell caps and does not require additional water. Each MF battery has a visual battery condition in­
dicator (Fig. 11). When an adequate battery charge

exists,
the indicator will have a GREEN dot. When
battery charging is necessary, the indicator will be dark. When the indicator is light brown colored or
yellow, the battery should be replaced.

CAUSES
OF
BATTERY DISCHARGING
It
is
normal
to
have
a
small
(5 to 20
milliamperes)
draw from
the
battery with
the
ignition
in the OFF

position,
and ALL
lamps OFF.
The
constant draw
is
due
to
various electronic features
or
accessories that
require electrical current with
the
ignition
OFF to

function properly.
If a
vehicle
is not
used
for a
period of
20
days
or
more,
the
black battery disconnect
should
be
disconnected.
The
disconnect
is
located
be­

hind
the
battery
on the
engine wiring harness. This will prevent battery discharging.

ABNORMAL
BATTERY
DISCHARGING
(1) Corroded battery posts
and
terminals.
(2) Loose
or
worn generator drive belt.
(3) Electrical loads that exceed
the
output
of the

charging system
due to
equipment
or
accessories
in­
stalled after delivery. (4) Slow driving speeds (heavy traffic conditions)
or prolonged idling with high-amperage electrical systems
in use.

(5) Defective electrical circuit
or
component caus­
ing excess Ignition
Off
Draw (IOD).
(6) Defective charging system.
(7) Defective battery.

IGNITION
OFF
DRAW
(IOD)
Ignition off draw refers to power being drained
from the battery with the ignition turned off. A nor­
mal vehicle electrical system will draw from 5 to 20
milliamps. A vehicle that has not been operated for
an extended period of time (approximately 20 days)
may discharge the battery to an inadequate level.
Battery drain should not exceed approximately 20
MA (20 milliamps = 0.020 amps). The 20 MA are needed to supply PCM memory,
digital clock memory, and ETR (electronically tuned
radio) memory. Excessive battery drain is caused by items left
turned on, internally shorted generator, or intermit­
tent short in wiring.
If the IOD is excessive (over 20 milliamperes), the
defect must be found and corrected before replacing a
battery. In most cases the battery can be charged and returned to service.
TEST PROCEDURE Testing for higher amperage IOD must be per­
formed first to prevent damage to most milliamp
meters.
Verify that all electrical accessories are OFF. Turn
off all lights, remove ignition key, and close all

doors.
If the vehicle is equipped with electronic acces­
sories (illuminated entry, high line radio), allow the
systems to automatically shut off (time out), up to 3
minutes.
(1) After determining that the underhood lamp is
operating properly then disconnect bulb. (2) Disconnect negative cable from battery.
(3) Connect a typical 12 volt test light (low watt­
age bulb) between the negative cable clamp and the
battery negative terminal. The test light may light brightly for up to 3 min­
utes or may not light at all (depending on the elec­
trical equipment). The term brightly being used
throughout the following tests, implies the bright­ ness of the test light will be the same as if it were
connected across the battery.
The test light must be securely clamped to the neg­
ative cable and battery terminal. If the test light be­
comes disconnected during any of the IOD test, the electronic timer function will be activated and all
tests must be repeated.
(4) After 3 minutes, the test light should turn OFF
or be DIMLY lit (depending on the electrical equip­

ment).
If the test light remains brightly lit do not
disconnect it. Remove each fuse or circuit breaker (refer to Group 8 - Wiring Diagrams) until test light
is either OFF or DIMLY lit. This will eliminate the
higher amperage draw.
If test light is still bright after disconnecting each
fuse and circuit breaker, disconnect the wiring har­ ness from the generator. Refer to Generator Testing
in this group. Do not disconnect the test light. After higher amperage IOD has been corrected, low
amperage IOD may be checked.
It is now safe to install milliamp meter to check for
low amperage IOD.
(5) With test light still connected, securely clamp
an ammeter between battery negative terminal and
negative battery cable.
If the test light or the milliamp meter circuit is
broken the various timer circuits will start. Do
not open any doors or turn on any electrical ac­ cessories with the test light disconnected or the
meter may be damaged.
(6) Disconnect test light. The current draw should
not exceed 0.020 amp. If it exceeds 20 milliamps iso­
late each circuit by removing circuit breakers and

fuses.
The meter reading drops once the high current
problem is found. Repair this section of the circuit,
whether it is a wiring short or component failure.

BATTERY
OPEN CIRCUIT VOLTAGE TEST
A battery voltage (no load) test will indicate the
state of charge of a battery that will pass the Battery
Load Test described in this section. Before proceed­
ing with this test or the Battery Load Test the
battery must be completely charged as de­ scribed in Battery Charging in this section. If a battery has a no load voltage reading of 12.4
volts or greater but will not endure a load test, it is
defective and should be replaced. Refer to Group 8B,
Battery/Starter Service for instructions. To test bat­
tery no load voltage, perform the following operation: (1) Before measuring open circuit voltage, the sur­
face charge must be removed from plates. Turn head lights on for 15 seconds then allow up to 5 minutes
for voltage to stabilize. (2) Remove both battery cables, negative first.
(3) Using a voltmeter connected to the battery

posts,
see instructions provided with voltmeter, mea­ sure open circuit voltage (Fig. 6). This voltage reading will indicate state of charge,
but will not reveal cranking capacity. Refer to Bat­
tery Open Circuit Voltage chart.

BATTERY
CHARGING
A battery is completely charged when it has:
• an open circuit voltage of 12.4 volts or more.
• has enough cranking capacity (minimum 9.6 volts
when loaded for 15 seconds to 50% of cold cranking amperage rating at 21°C/70°F). A green color, in the test indicator on the top of the
battery, indicates the battery is charged enough for
further testing. A black color indicates the battery
voltage state of charge is below 75%. A yellow or
bright color indicates the battery has excessively low electrolyte level. The battery cannot be refilled or
charged, it must be replaced.

charging, immediately reduce charging rate or turn
off charger and evaluate battery condition.
Some battery chargers are equipped with polarity
(+ to +/- to -) sensing devices to protect the charger
or battery from being damaged if improperly con­
nected. If the battery state of charge is too low for
the polarity sensor to detect, the sensor must be by­
passed for charger to operate. Refer to operating in­ structions provided with battery charger being used.

battery to use. If battery will not endure a load test, it must be replaced. Clean and inspect battery hold
downs, tray, terminals, posts, and top before complet­
ing service, see Group 8B - Battery/Starter/Generator Service.
CHARGING TIME REQUIRED The time required to charge a battery will vary de­
pending upon the following factors:

•

ELECTRICAL
8A - 7
(1) Size
of
Battery—
A
completely discharged
large heavy-duty battery requires more than twice
the recharging time
as a
completely discharged small capacity battery.

WARNING: NEVER EXCEED
20
AMPS
WHEN
CHARGING
A
COLD
(-1°C/30°F)
BATTERY,
PER­

SONAL
INJURY
MAY RESULT.
(2) Temperature—
A
longer time will
be
needed
to charge
a
battery
at -18°C (0°F)
than
at
27°C
(80°F).
When
a
fast charger
is
connected
to a
cold
battery, current accepted
by
battery will
be
very
low
at first. Then,
in
time,
the
battery will accept
a

higher rate
as
battery warms.
(3) Charger Capacity—
A
charger that supplies
only
5
amperes requires
a
much longer charging
time than
a
charger that supplies
20
amperes.
(4) State
Of
Charge—
A
completely discharged
battery requires more charging time than
a
partially charged battery. Electrolyte
is
nearly pure water
in a

completely discharged battery.
At
first
the
charging
current amperage will
be low. As
acid
is
forced from
the plates, inside
the
battery,
the
current amperate
will rise. Also,
the
specific gravity
of the
electrolyte will rise, bringing
the
green
dot
into view.

CHARGING
COMPLETELY
DISCHARGED

BATTERY

The following procedure should
be
used
to
recharge
a completely discharged battery. Unless procedure
is

properly followed,
a
good battery
may be
needlessly replaced.
(1) Measure voltage
at
battery posts with
a
volt­
meter, accurate
to 1/10
volt
(Fig, 11). If
below
10

volts,
then charge current will
be low and it
could
take some time before
it
accepts
a
current
in
excess of
a few
milliamperes. Such
low
current
may not be

detectable
on
ammeters built into many chargers.
(2) Connect charger leads. Some chargers feature
polarity protection circuitry which prevents operation
unless charger
is
connected
to
battery posts correctly.
A completely discharged battery
may not
have enough voltage
to
activate
the
protection circuitry,
even though leads
are
connected properly. This
makes
it
appear that battery will
not
accept charging
current. Refer
to
instructions provided with battery
charger being used.
