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.

GENERAL
INFORMATION plied from the fuse block and grounded in the horn The horn system consists of a horn switch, horn re- switch. When the horn switch on the steering column
lay (located on the fuse block), horns, and all their is pressed, the ground circuit is completed, energiz-
wiring and connections. The circuit voltage is sup- ing the relay, and supplying power to the horns.

TEST PROCEDURES
HORNS
WILL
NOT
SOUND
If the horns do not sound, check for a blown horn
fuse in cavity number 4 of the fuse block. If the fuse is blown, replace it with the same type fuse. If the
horns fail to sound and the newly replaced fuse blows
the horn switch is depressed, check for one of the fol­ lowing:
• a short circuit in the horn
• the horn wiring between the fuse terminal and the
horn is faulty. If the fuse is intact, unplug wire connector at horn.
Connect one lead of a test lamp to the wire connector and the other lead to a good body ground (Fig. 1).
Depress the horn switch. Should test lamp illuminate
the horn is ungrounded or faulty. Ground can be checked by using a jumper wire between horn
bracket (scratch through paint) and the battery neg­ ative terminal. If the horn still fails to sound with
the ground jumper wire still intact and the horn re­ connected, replace the horn. If the lamp fails to illuminate, check for a defective
horn relay by substituting a known good horn relay in the circuit. If the lamp illuminates when depress­
ing the horn switch, the original relay is defective. If
the lamp fails to illuminate with a known good relay, unplug that relay. Connect a jumper wire from the
battery terminal to the horn terminal on the relay
terminal board. If the lamp, connected in place of the
horns, fails to illuminate, inspect for an open circuit
between the horn fuse and the horn terminal on the relay. Also check between relay terminal board and
the horn terminals. Should the lamp illuminate, a defective horn switch or an open circuit in the wiring
between the relay terminal and the horn switch is at fault.

HORNS SOUND CONTINUOUSLY
Should the horns sound continuously, unplug the
horn relay from the relay connector inside the pas-

unclear as to what a system may be called.
Diagram pages are arranged starting with the bat­
tery and fuses. Then working into charging, starting, and ignition systems. After this they start at the
front of the vehicle and work to rear of the vehicle.
The diagrams end with connector identification

pages.

COMPONENT
IDENTIFICATION
To find a components actual location on the vehicle
refer to the wiring and components section index. This section shows the wire harness routing and the compo­
nents location in the vehicle. When using this section
refer to the wiring diagrams for the general location of
the component. Then use the component identification index to locate the proper figure number.

SPLICE
LOCATIONS
Splices are indicated in the wiring diagrams by a
diamond with splice circuit code within it (Fig. 5 ex­ ample 1). If there is more than one splice per circuit
splice code a small box will be connected to the dia­
mond with the splice number in it (Fig. 5 example 2). To locate a splice in the wire harness determine
the splice number from the wiring diagrams, then re­
fer to the splice location index. This section shows
the general location of the splice in the harness.

TROUBLESHOOTING
WIRING
PROBLEMS
When troubleshooting wiring problems there are
six steps which can aid in the procedure. The steps
are listed and explained below. (1) Verify the problem.
(2) Verify any related symptoms. Perform opera­
tional checks on components in the same circuit as the problem area. Refer to the wiring diagram fuse
application chart for circuit information. (3) Analyze the symptoms. Use the wiring dia­
grams to determine what the circuit is doing, where
the problem most likely is occurring and where the diagnosis will continue. (4) Isolate the problem area. (5) Repair the problem.
(6) Verify proper operation. For this step check for
proper operation of all items on the circuit repaired. Refer to the wiring diagram fuse application chart.

FUSIBLE
LINKS
Vehicle wiring harnesses are equipped with fusible

links.
For protection against harness damage in the
event of a short. Fusible links are color coded as to
wire gauge size. Refer to the fusible link chart for color and gauge identification (Fig. 6).

When a fusible link blows it is important to find
out what the problem is. They are placed in the elec­
trical system for protection against shorts to ground
that can be caused by a component or various wiring
failures. Do not just replace the fusible link to correct the problem.
When diagnosing a faulty fusible link it is impor­
tant to check the wire carefully. In some instances
the link may be blown and it will not show through the insulation, the wire should be checked over its
entire length for internal breaks.
(1) Disconnect battery negative cable.
(2) Cut out the blown portion of the fusible link.
(3) Strip 1 inch of insulation from each end of the
existing fusible link.
(4) Place a piece of heat shrink tubing over one
side of the fusible link. Make sure the tubing will be
long enough to cover and seal the entire repair area.
(5) Cut a replacement piece of fusible link approx­
imately two inches longer than the piece removed. (6) Remove one inch of insulation from each end of
the replacement fusible link.
