To read the built-in indicator, look into the sight
glass and note the color of the indication (Fig. 8). The
battery condition that each color indicates is
described in the following list:
²Green- Indicates 75% to 100% battery state-of-
charge. The battery is adequately charged for further
testing or return to service. If the starter will not
crank for a minimum of fifteen seconds with a fully-
charged battery, the battery must be load tested.
Refer to Standard Procedures for the proper battery
load test procedures.
²Black or Dark- Indicates 0% to 75% battery
state-of-charge. The battery is inadequately charged
and must be charged until a green indication is visi-
ble in the sight glass (12.4 volts or more), before the
battery is tested further or returned to service. Refer
to Standard Procedures for the proper battery charg-
ing procedures. Also refer to Diagnosis and Testing
for more information on the possible causes of the
discharged battery condition.
²Clear or Bright- Indicates a low battery elec-
trolyte level. The electrolyte level in the battery is
below the built-in indicator. A maintenance-free bat-
tery with non-removable cell caps must be replaced if
the electrolyte level is low. Water must be added to a
low-maintenance battery with removable cell caps
before it is charged. Refer to Standard Procedures for
the proper battery filling procedures. A low electro-
lyte level may be caused by an overcharging condi-
tion. Refer to Charging System for the proper
charging system diagnosis and testing procedures.
STANDARD PROCEDURE - HYDROMETER TEST
The hydrometer test reveals the battery state-of-
charge by measuring the specific gravity of the elec-
trolyte.This test cannot be performed on
maintenance-free batteries with non-removable
cell caps.If the battery has non-removable cell caps,
refer to Diagnosis and Testing for alternate methods
of determining the battery state-of-charge.
Specific gravity is a comparison of the density of
the battery electrolyte to the density of pure water.Pure water has a specific gravity of 1.000, and sulfu-
ric acid has a specific gravity of 1.835. Sulfuric acid
makes up approximately 35% of the battery electro-
lyte by weight, or 24% by volume. In a fully-charged
battery the electrolyte will have a temperature-cor-
rected specific gravity of 1.260 to 1.290. However, a
specific gravity of 1.235 or above is satisfactory for
the battery to be load tested and/or returned to ser-
vice.
Before testing, visually inspect the battery for any
damage (a cracked case or cover, loose posts, etc.)
that would cause the battery to be faulty. Then
remove the battery cell caps and check the electrolyte
level. Add distilled water if the electrolyte level is
below the top of the battery plates. Refer to Battery
System Cleaning for the proper battery inspection
procedures.
See the instructions provided by the manufacturer
of the hydrometer for recommendations on the cor-
rect use of the hydrometer that you are using.
Remove only enough electrolyte from the battery cell
so that the float is off the bottom of the hydrometer
barrel with pressure on the bulb released. To read
the hydrometer correctly, hold it with the top surface
of the electrolyte at eye level (Fig. 9).
CAUTION: Exercise care when inserting the tip of
the hydrometer into a battery cell to avoid damag-
ing the plate separators. Damaged plate separators
can cause early battery failure.
Hydrometer floats are generally calibrated to indi-
cate the specific gravity correctly only at 26.7É C.
When testing the specific gravity at any other tem-
perature, a correction factor is required. The correc-
tion factor is approximately a specific gravity value
of 0.004, which may also be identified as four points
of specific gravity. For each 5.5É C above 26.7É C, add
four points. For each 5.5É C below 26.7É C, subtract
four points. Always correct the specific gravity for
temperature variation.
EXAMPLE:A battery is tested at -12.2É C and has
a specific gravity of 1.240. Determine the actual spe-
cific gravity as follows:
(1) Determine the number of degrees above or
below 26.7É C:26.7É C + -12.2É C = 14.5É C below
the 26.7É C specification
(2) Divide the result from Step 1 by 5.5É C:14.5É
C ÷ 5.5É C = 2.64
(3) Multiply the result from Step 2 by the temper-
ature correction factor (0.004):2.64 X 0.004 = 0.01
(4) The temperature at testing was below 26.7É C;
therefore, the temperature correction factor is sub-
tracted:1.240 - 0.01 = 1.23
(5) The corrected specific gravity of the battery cell
in this example is 1.23.

Test the specific gravity of the electrolyte in each
battery cell. If the specific gravity of all cells is above
1.235, but the variation between cells is more than
fifty points (0.050), the battery should be replaced. If
the specific gravity of one or more cells is less than
1.235, charge the battery at a rate of approximately
five amperes. Continue charging the battery until
three consecutive specific gravity tests, taken at one-
hour intervals, are constant. If the cell specific grav-
ity variation is more than fifty points (0.050) at the
end of the charge period, replace the battery.
When the specific gravity of all cells is above 1.235,
and the cell variation is less than fifty points (0.050),
the battery may be load tested to determine its
cranking capacity. Refer to Standard Procedures for
the proper battery load test procedures.
STANDARD PROCEDURE - OPEN-CIRCUIT
VOLTAGE TEST
A battery open-circuit voltage (no load) test will
show the approximate state-of-charge of a battery.
This test can be used in place of the hydrometer test
when a hydrometer is not available, or for mainte-
nance-free batteries with non-removable cell caps.
Before proceeding with this test, completely charge
the battery (Refer to 8 - ELECTRICAL/BATTERY
SYSTEM/BATTERY - STANDARD PROCEDURE).(1) Before measuring the open-circuit voltage, the
surface charge must be removed from the battery.
Turn on the headlamps for fifteen seconds, then
allow up to five minutes for the battery voltage to
stabilize.
(2) Disconnect and isolate both battery cables, neg-
ative cable first.
(3) Using a voltmeter connected to the battery
posts (see the instructions provided by the manufac-
turer of the voltmeter), measure the open-circuit volt-
age (Fig. 10).
See the Open-Circuit Voltage Table. This voltage
reading will indicate the battery state-of-charge, but
will not reveal its cranking capacity. If a battery has
an open-circuit voltage reading of 12.4 volts or
greater, it may be load tested to reveal its cranking
capacity (Refer to 8 - ELECTRICAL/BATTERY SYS-
TEM/BATTERY - STANDARD PROCEDURE).

11.7 volts or less 0%
12.0 volts 25%
12.2 volts 50%
12.4 volts 75%
12.6 volts or more 100%
STANDARD PROCEDURE - LOAD TEST
A battery load test will verify the battery cranking
capacity. The test is based on the Cold Cranking
Amperage (CCA) rating of the battery. To determine
the battery CCA rating, see the label affixed to the
battery case or refer to Battery Specifications for the
proper factory-installed specifications.
Before proceeding with this test, completely charge
the battery (Refer to 8 - ELECTRICAL/BATTERY
SYSTEM/BATTERY - STANDARD PROCEDURE).

(1) Disconnect and isolate both battery cables, neg-
ative cable first. The battery top and posts should be
clean (Refer to 8 - ELECTRICAL/BATTERY SYSTEM
- CLEANING).
(2) Connect a suitable volt-ammeter-load tester
(Fig. 11) to the battery posts (Fig. 12). See the
instructions provided by the manufacturer of the
tester you are using. Check the open-circuit voltage
(no load) of the battery (Refer to 8 - ELECTRICAL/
BATTERY SYSTEM/BATTERY - STANDARD PRO-
CEDURE). The battery open-circuit voltage must be
12.4 volts or greater.
(3) Rotate the load control knob (carbon pile rheo-
stat) to apply a 300 ampere load to the battery for
fifteen seconds, then return the control knob to the
Off position (Fig. 13). This will remove the surface
charge from the battery.(4) Allow the battery to stabilize to open-circuit
voltage. It may take up to five minutes for the bat-
tery voltage to stabilize.
(5) Rotate the load control knob to maintain a load
equal to 50% of the CCA rating of the battery (Fig.
14). After fifteen seconds, record the loaded voltage
reading, then return the load control knob to the Off
position.
(6) The voltage drop will vary with the battery
temperature at the time of the load test. The battery
temperature can be estimated by using the ambient
temperature during the past several hours. If the
battery has been charged, boosted, or loaded a few
minutes prior to the test, the battery will be some-
what warmer. See the Load Test Temperature Table
for the proper loaded voltage reading.

GENERATOR
DESCRIPTION
The generator is belt-driven by the engine using a
serpentine type drive belt. It is serviced only as a
complete assembly. If the generator fails for any rea-
son, the entire assembly must be replaced.
OPERATION
As the energized rotor begins to rotate within the
generator, the spinning magnetic field induces a cur-
rent into the windings of the stator coil. Once the
generator begins producing sufficient current, it also
provides the current needed to energize the rotor.
The stator winding connections deliver the induced
AC current to 3 positive and 3 negative diodes for
rectification. From the diodes, rectified DC current is
delivered to the vehicle electrical system through the
generator battery terminal.
Although the generators appear the same exter-
nally, different generators with different output rat-
ings are used on this vehicle. Be certain that the
replacement generator has the same output rating
and part number as the original unit. Refer to Spec-
ifications and see Generator Ratings for amperage
ratings and part numbers.
Noise emitting from the generator may be caused
by: worn, loose or defective bearings; a loose or defec-
tive drive pulley; incorrect, worn, damaged or misad-
justed fan drive belt; loose mounting bolts; a
misaligned drive pulley or a defective stator or diode.
