(7) If the voltmeter reading fell below 9.6 volts,
with the battery temperature at a minimum of 70ÉF
(21ÉC), replace the battery.
BATTERY CHARGING
A battery is completely charged when it has:
²an open circuit voltage of 12.4 volts or more.
²has enough cranking capacity (minimum 9.6 volts
when loaded for 15 seconds to 50% of cold crank am-
perage rating at 21ÉC (70ÉF).
An open circuit voltage of 12.4 volts or greater, in-dicates battery is charged enough for further testing
and possible return to use.
WARNING: DO NOT CHARGE A BATTERY THAT
HAS LOW ELECTROLYTE LEVEL. BATTERY MAY
ARC INTERNALLY AND EXPLODE.
WARNING: EXPLOSIVE GASES FORM OVER BAT-
TERY, DO NOT SMOKE, USE FLAME, OR CREATE
SPARKS NEAR BATTERY.
WARNING: DO NOT ASSIST BOOST OR CHARGE A
FROZEN BATTERY, CASING MAY FRACTURE.
WARNING: POISON, CAUSES SEVERE BURNS.
BATTERY CONTAINS SULFURIC ACID, AVOID CON-
TACT WITH SKIN, EYES, OR CLOTHING. IN EVENT
OF CONTACT, FLUSH WITH WATER AND CALL
PHYSICIAN IMMEDIATELY. KEEP OUT OF REACH
OF CHILDREN.
CAUTION: Always disconnect the battery negative
cable before charging battery to avoid damage to
electrical systems. Do not exceed 16.0 volts while
charging battery.
Battery electrolyte will bubble inside case while
being charged properly. If the electrolyte boils or is
discharged from the vent holes while charging, im-
mediately reduce charging rate or turn OFF charger
and evaluate battery condition.
Battery should not be hot to touch.
If the battery feels hot to the touch, turn OFF
charger and let cool before restarting.
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.

JBATTERY/STARTING/CHARGING SYSTEMS DIAGNOSTICS 8A - 5

After the battery has been charged to 12.4 volts or
greater, perform a load test to determine cranking
capacity. If the battery will endure a load test, re-
turn the battery to use. If battery will not endure a
load test, it must be replaced. Clean and inspect bat-
tery holddowns, tray, terminals, posts, and top before
completing 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:
(1)Size of BatteryÐA 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 (-1ÉC/30ÉF) BATTERY, PER-
SONAL INJURY MAY RESULT.
(2)TemperatureÐA longer time will be needed
to charge a battery at -18ÉC (0ÉF) than at 27ÉC
(80ÉF). 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 CapacityÐA charger, that supplies
only 5 amperes, will require a longer charging time
than a charger that supplies 20 amperes or more.
(4)State Of ChargeÐA 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 the battery charges
the specific gravity of the electrolyte will rise slowly.
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. 8). If below 10
volts, then charge current will be low and it could
take some time before it accepts a current greater
than 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 that prevents operation
unless charger is connected to battery posts correctly.
A completely discharged battery may not have
enough voltage to activate this circuitry, even
though leads are connected properly. This makes itappear that battery will not accept charging current.
Refer to instructions provided with battery charger
being used.
(3) Battery chargers vary in the amount of voltage
and current they provide. For time required for bat-
tery to accept measurable charger current at various
voltages, refer to Charge Rate chart. If charge cur-
rent is still not measurable at end of charging times,
the battery should be replaced. If charge current is
measurable during charging time, the battery may
be good and charging should be completed in the nor-
mal manner.

post and terminal cleaner, and a sodium bicarbonate/
water solution. Replace cables that have damaged or
deformed terminals.
Be sure filler caps or vents are installed when
washing battery to prevent solution from enter-
ing battery.
(2) Clean outside of battery case if the original
battery is to be installed. Clean top cover with di-
luted ammonia or a sodium bicarbonate/water solu-
tion to remove acid film. Flush with clean water.
Ensure that cleaning solution does not enter cells.
(3) Remove corrosion from the terminals with a
wire brush or post and terminal cleaner. Inspect the
case for cracks or other damage that would result in
leakage of electrolyte.
(4) Check electrolyte level in the battery. Use a
putty knife or other suitable wide tool to pry filler
caps off low maintenance battery (Fig. 1). Do not use

ENGINE COOLANT TEMPERATURE SENSOR TEST
To perform a complete test of this sensor and its
circuitry, refer to the DRB scan tool. Also refer to the
appropriate Powertrain Diagnostics Procedures man-
ual. To test the sensor only, refer to the following:
The sensor is installed in the thermostat housing
(Fig. 12).
(1) Disconnect wire harness connector from sensor
(Fig. 12).
(2) Test the resistance of the sensor with a high in-
put impedance (digital) volt-ohmmeter. The resis-
tance should be less than 1340 ohms at normal
engine operating idle temperature. For resistance
values, refer to the Sensor Resistance chart. Replace
the sensor if it is not within the range of resistance
specified in the chart.
(3) Test continuity of the wire harness. This is
done between Powertrain Control Module (PCM)
wire harness connector terminal-2 and the sensor
connector terminal. Also check continuity between
wire harness terminal-4 to the sensor connector ter-
minal. Repair the wire harness if an open circuit is
indicated.
IGNITION SECONDARY CIRCUIT DIAGNOSIS
CHECKING FOR SPARK
CAUTION: When disconnecting a high voltage cable
from a spark plug or from the distributor cap, twist
the rubber boot slightly (1/2 turn) to break it loose.
Grasp the boot (not the cable) and pull it off with a
steady, even force.
(1) Disconnect the ignition coil secondary cable
from center tower of the distributor cap. Hold the ca-
ble terminal approximately 12 mm (1/2 in.) from a
good engine ground (Fig. 13).WARNING: BE VERY CAREFUL WHEN THE ENGINE
IS CRANKING. DO NOT PUT YOUR HANDS NEAR
THE PULLEYS, BELTS OR THE FAN. DO NOT
WEAR LOOSE FITTING CLOTHING.
(2) Rotate (crank) the engine with the starter mo-
tor and observe the cable terminal for a steady arc. If
steady arcing does not occur, inspect the secondary
coil cable. Refer to Spark Plug Cables in this group.
Also inspect the distributor cap and rotor for cracks
or burn marks. Repair as necessary. If steady arcing
occurs, connect ignition coil cable to the distributor
cap.
(3) Remove a cable from one spark plug.

(4) Using insulated pliers, hold the cable terminal
approximately 12 mm (1/2 in.) from the engine cylin-
der head or block while rotating the engine with the
starter motor. Observe the spark plug cable terminal
for an arc. If steady arcing occurs, it can be expected
that the ignition secondary system is operating cor-
rectly. If steady arcing occurs at the spark plug ca-
bles, but the engine will not start, connect the DRB
scan tool. Refer to the Powertrain Diagnostic Proce-
dures service manual for DRB operation.
FAILURE TO START TEST
To prevent unnecessary diagnostic time and wrong
test results, the previous Checking For Spark test
should be performed prior to this test.
WARNING: SET PARKING BRAKE OR BLOCK THE
DRIVE WHEELS BEFORE PROCEEDING WITH THIS
TEST.
(1) Unplug the ignition coil harness connector at
the coil (Fig. 14).
(2) Connect a set of small jumper wires (18 gauge
or smaller) between the ignition coil and coil electri-
cal connector (Fig. 15).
(3) Determine that sufficient battery voltage (12.4
volts) is present for the starting and ignition sys-
tems.
(4) Crank the engine for 5 seconds while monitor-
ing the voltage at the coil positive terminal:
²If the voltage remains near zero during the entire
period of cranking, refer to On-Board Diagnostics in
Group 14, Fuel Systems. Check the powertrain con-
trol module (PCM) and auto shut down relay.
²If voltage is at near battery voltage and drops to
zero after 1-2 seconds of cranking, check the cam-
shaft position sensor-to-PCM circuit. Refer to On-
Board Diagnostics in Group 14, Fuel Systems.
²If voltage remains at near battery voltage during
the entire 5 seconds, turn the key off. Remove the60-way connector (Fig. 16) from the PCM. Check 60-
way connector for any spread terminals.
(5) Remove test lead from the coil positive termi-
nal. Connect an 18 gauge jumper wire between the
battery positive terminal and the coil positive termi-
nal.
(6) Make the special jumper shown in Figure 17.
Using the jumper,momentarilyground terminal-19
of the 60-way connector. A spark should be generated
at the coil cable when the ground is removed.
(7) If spark is generated, replace the powertrain
control module (PCM).
(8) If spark is not seen, use the special jumper to
ground the coil negative terminal directly.
(9) If spark is produced, repair wiring harness for
an open condition.

With the ignition switch in the ON or START posi-
tion, voltage supplied to the instrument cluster is lim-
ited by fuse #17. The voltage is supplied to all the
gauges and indicator lamps through the instrument
cluster printed circuit.
With the ignition switch in the OFF position, volt-
age is not supplied to the instrument cluster and the
gauges do not indicate any vehicle condition.
VOLTMETER
The voltmeter measures battery or generator out-
put voltage, whichever is greater.
OIL PRESSURE GAUGE
The oil pressure gauge pointer position is controlled
by a magnetic field created by electrical current flow
through the coils within the gauge. A change in current
flow will change the magnetic field which changes the
pointer position. The oil pressure sender is a variable
resistor that changes electrical resistance with a change
in oil pressure (values shown in Specifications chart).
OIL PRESSURE INDICATOR LAMP
Voltage is supplied to one side of the indicator bulb
and the oil pressure switch is connected to the other
side. When oil pressure is too low the switch closes
providing a path to ground, and the indicator bulb
lights.
COOLANT TEMPERATURE GAUGE
The coolant temperature gauge pointer position is
controlled by a magnetic field created by electrical
current flow through the coils within the gauge. A
change in current flow will change the magnetic field
which changes the pointer position. The coolant tem-
perature sensor is a thermistor that changes electri-
cal resistance with a change in coolant temperature
(values shown in Specifications chart).
