How to Print Wiring Diagram Pages
Many of the original Ford wiring manuals were created in a very large format (11x17, 17x24,
and 17x36) making it difficult to print on a standard home printer. Some printers will print only a
portion of the entire page, while others will shrink the page into an unreadable format. However,
Adobe Reader has the ability to print sections (known as Tiles) of the page onto standard
8.5x11 paper. Please use the steps below to print these wiring diagrams.
l
You can print a large format document, such as these w iring
diagrams, by splitting the page across multiple sheets of paper
(called "tiling"). The tiling option calculates how many sheets of
paper are needed. You can adjust the size of the original to
best fit the paper and specify how much each "tile" overlaps.
You can then piece together the tiles.
1. Choose File > Print.
2. From the Page Scaling pop-up menu, select one of the following options:
Tile Large Pages Tile only the pages that are larger than the paper.
Tile All Pages Tile all the pages in the PDF

Note: If the tile options are not in the menu, make
sure that the following options are not selected in
the Advanced Print dialog box: Print As Image or,
for Acrobat only, Separations or In-RIP
Separations. Also check your version of Reader.
Reader 9 does not support tiling.
- - ·- •
- »--
3. Set the following options as needed:
Tile Scale Scales the pages by the amount
you specify.
Overlap Determines the amount each tile overlaps adjacent tiles.
Cut Marks Adds guide marks to each page to help you trim the overlap.
Labels Adds the filename and page number on each "tile".
4. Click OK

HOW TO USE THE WIRING DIAGRAMS
INDEX
An INDEX is provided behind the divider for each
truck series. The index page contains an alphabetically arranged list of systems and components and a bulb usage list. The index lists the
location of the components on the drawing. Examples of the two types of index references are
shown:
A. To locate an electrical part at D-49, find the
location number 49 at the top of the illustration. Then, find the letter Don the side of the
illustration. Follow the number and the letter until the lines intersect. The part will be
within an inch or two of the intersection.
B. To locate an electrical part at PG3-D10, turn
to page 3 as indicated in the lower right
corner of the sheet. Then, find the number
10 at the top of the illustration and the letter
D on the side of the illustration. Follow the
number and the letter until the lines intersect. The part will be within an inch or two of
the intersecting lines.
BASIC INFORMATION
Generally, the power supply for all components
on this drawing comes from the top of the page
and over to the battery at the left.
The ground for each component is always toward
the bottom of the drawing that are explained as
follows:
•Ground symbols are shown in Figure 1. A
ground wire connected away from the component is indentified by a code G1 or G2, etc.
The location of the remote ground is listed in
the GROUND CODES chart and the bottom
of the page.
_._
• Wire color code is shown in Figure 2. Wire
color codes (by color) are listed on page 5.

If a vehicle specific wire color in a connector does
not match the diagram shown, it can usually be
identified by comparing the other colors shown at
the wire connectors. Specific wire color deviations in the manufacturing of a wire harness are
usually for a short duration.

This 1978 Truck Shop Manual has been prepared to provide information
covering normal service repairs and maintenance for 1978 Ford Trucks
manufactured in the United States and Canada. It is divided into five
volumes, each covering a specific major area:
Volume 1 - Chassis
Volume 2 - Engine
Volumes 3 & 4 - Body and Electrical
Volume 5 - Pre-Delivery, Maintenance and Lubrication.
Information in each volume is divided into Groups covering a general
system.
For 1978, the basic part number for components covered in the Group is also
included in parenthesis after the Group number.
Example:
Cooling System
~

Some components covered within a Group do not have the same basic part
number. In these cases, more than one basic part number will appear on the
Group index.

For easy reference, information in each Group has been divided into smaller
units or Parts. There is one Part for each component in the system, as well as
a General Service Part in some Groups to cover procedures common to
several components within the Group. In general, each Part contains the
Description, Operation, Diagnosis and Testing, Removal and Installation
and Disassembly and Assembly procedures for the component covered in
the Part. Diagnosis Charts are also included in some Parts to help you
systematically locate and correct problems encountered. In most cases,
specifications are included at the end of each Part.
To aid in locating specific items in·this manual, the index at the front of each
volume provides an alphabetical listing, with page number, for all Parts in
the volume. The tab locator on the right side of this index will help you find
the first page of each Group.
On the first page of each Group there is an index listing the Part title and Part
number for each component covered within the Group. The first page of
each Part contains an index to locate service operations covered in that
Part. This Group-Part breakdown is also indicated in the page number
located at the top of each page.
Example:
11-02-21
=
(Group) 11 - (Part) 02 - (Page) 21
Metric conversion tables have been included at the back of each volume to
aid in converting specifications in this manual to the metric equivalent.
The descriptions and specifications in this manual were in effect at the time
this manual was approved for printing. Ford Motor Company reserves the
right to discontinue models at any time, or change specifications or design
without notice and without incurring obligation.

DESCRIPTION AND OPERATION
The alternator charging system is a
negative ground system, and consists of
an alternator , r egulator, c harge
indicator, storage battery, fuse link and
associated wiring. Refer to the Wiring
Diagram Manual for schematics and
locations of wiring harnesses.
FUSE LINK
The fuse link used on the Bronco,
Econoline , Club Wagons, Parcel
Delivery and light trucks, is a short
length of insulated wire integral with the
engine compartment wii'ing harness. It Ii
several wire gages smaller than the
circuit that it protects and is the color of
the circuit being supplied by the fuse
link. Service fuse links are green or black
depending on usage; All fuse links h&Te
a flag moulded on the wire or on the
terminal insulator. Color identification
of the nag or connector is Red-18 gage
wire, Orange-16 pge wire, or Green14 gage wire.
The fuse link is designed to bum out,
thus protecting the alternator and wiring
when heavy reverse current nows, such
as when a booster battery is connected
incorrectly, M a short to ground occurs
i.n the wiring harness.
A burned out link may have bare wire
ends protruding from the insulation, or
it may only have expanded or bubbled
insulation. If it is hard to determine if the
link is burned out, perform a continuity
test.
Refer to Part 34-31 for testing
procedures for fuse links used in the
charging system.

DIAGNOSIS
Certain tests outlined in the Parts
within this Group are illustrated in the
schemati~ and in pictorial form. The
schematic illustrates the internal
connections of the Rotunda or equivalent
equipment so these connections can be
duplicated when this equipment is not
available. The various circuits involved
in the tests can be selected by means of
switches without the necessity of
changing connections when the
illustrated equipment is used. This
reduces the time required to test units
and circuits on the vehicle.
PRELIMINARY INFORMATION
Before performing charging or
starting system tests on the vehicle, note
the complaint such as: slow cranking,
battery dead or using an excessive
amount of water, top of battery wet,
ammeter shows charge at all times and/
or no charge, alternator warning lamp
does not come on and/or never goes out.
This information will aid in isolating the
part of the system causing the symptom.
Next, visually inspect as follows:
1. Check the fuse link located between
the starter solenoid and the
alternator. Replace the fuse link if
burned.
2. Check battery posts and battery cable
terminals for clean and tight
connections. Remove the battery
cables (if corroded), clean and install
them securely.
3. Check for clean and tight wiring
connections at the alternator,
regulator and engine.
4. Check the alternator belt tension and
tighten to specification (if necessary),
as shown in Part 31-10.
ISOLATING THE PROBLEM
Battery, starting system, and light
systems problems can be caused by poor
charging system performance. It is also
possible to suspect the charging system
because of an overload in another area of
the electrical system.
To avoid guesswork, it is necessary to
isolate the battery, the charging system,
and the electrical circuits to correctly
identify the area where the difficulty lies.
The best method to do this is to check the
battery first before any electrical system
diagnosis. The battery must be in proper
state of charge. The battery must be
operating properly before the other areas
of the electrical system can perform
normally.
BATTERY CHECK
The battery should be checked to see
if it has the capacity and ability to accept
and hold a charge. If the battery is good,
then the charging system should be
checked to see that it performs its
function of keeping the battery charged.
The battery capacity, specific gravity
and cell comparison test will determine
the ability of a battery to accept and hold
a charge. If the battery cannot meet the
specifications it should be replaced and
the new battery fully charged before
further diagnosis of other areas of the
electrical system.
If the battery is found to meet the
required specifications, it should be fully
charged before proceeding with the
diagnosis of other electrical system
components.
CHARGING SYSTEM CHECK
The General Charging System Test
should be performed before testing any of
the individual charging system
components. It's "road-map" type of
layout should reduce confusion in
determining "what to do next" and speed
up diagnosis. The component tests will
determine the type of component repairs
to be made.
The test instruments used in the
General Charging System Test are a
voltmeter (0-20 or 0-30 volt scale) and an
ohmmeter. Special care should be given
when using the ohmmeter near "hot"
circuits. The component to be checked
should be disconnected from the circuit
or the battery terminals should be
disconnected.
Continue through the Diagnosis
Guides until a repair has bet!n made.
Then, again test the system to see if the
repair has corrected the system problem.

TESTING
A voltmeter (0 to 20 volt scale),
ohmmeter, jumper wire and a test light
(12 volt) are the only tools required to
perform an accurate check of the
complete charging system. The meters
should be calibrated once a year and the
date of calibration stamped on the meter
face. It is recommended that this practice
be followed by all technicians to maintain
their meters at acceptable accuracy.
The tests are divided into On Vehicle
and On Bench Test procedures.
Troubleshooting or diagnosis is
required before actual repairs can be
m"rl"' in th,. ,.J,.ctrical svstem. Even where
an obvious fault makes the replacement
of a unit necessary, find out why the unit
failed. Refer to the Diagnosis Guide in
this Part. When a trouble is diagnosed
correctly, unnecessary repairs are
prevented, the time the vehicle is out of
service will be decreased, and the repairs
that are made will be permanent.
ON VEHICLE TESTS
Before performing charging system
tests on the vehicle, note the complaint
such as: slow cranking, battery dead or
using an excessive amount of water, top
of batterv wet. ammeter shows charge at
all times or no charge, alternator warning
lamp does not come on or never goes out.
This information will aid in isolating the
part of the system causing the symptom.
Visual Inspection
1. Check the fuse link if so equipped
located between the starter relay and
the alternator. If burned, determine
cause, repair system and replace fuse
link.
2. The battery must be in proper state of
charge (at least 1.200 specific
gravity). Check the battery posts and
battery cable terminals for clean and

I. Connect the ohmmeter probes
between each pair of stator leads (3
different ways). The ohmmeter must
show equal readings for each pair of
stator leads. Replace the stator if the
readings are not the same.
2. Set the ohmmeter Multiply By knob
at 1000. Connec t the ohmmeter
probes to one of the stator leads and
to the stator laminated core. Be sure
that the probe makes a good electrical
connection with the stator core. The
meter should show an infinite reading
(no meter movement).
3. If the meter does not indicate an
infinite reading (needle moves), the
FIG. 8 Diode Test-leece Neville
Alternator
stator winding is shorted to the core
and must be replaced. Repeat this test
for each of the stator leads.
Rotor Open or Short Circuit Test
Disassemble the front housing and
rotor from the rear housing and stator as
outlined under Disasse mbly in the
appropriate alternator part in Group 31 .
Set the ohmmeter Multiply By knob at
I and calibrate the meter as directed
inside the ohmmeter cover.
I. Contact each ohmmeter probe to a
rotor slip ring (Fig. 9). The meter
reading should be 2.4 to 4.9 ohms. A
higher reading indicates a weak or
broken slip ring solder connection or
a broken wire. A lower reading
indicates a shorted wire or slip ring.
Replace the rotor if it cannot be
repaired.
2. Contact one ohmmeter probe to a slip
ring and the other probe to the rotor
shaft. The meter reading should be
infinite (no deflection).
3. A reading other than infinite indicates
the rotor is shorted to the shaft .
Inspect the sli p ring soldered
terminals to be sure they are not bent
and touching the rotor shaft, or that
excess solder is not grounding the
rotor coil connections to the shaft.
Replace the rotor if it is shorted and
cannot be repaired.

GENERAL INFORMATION
DANGER-EXPLOSIVE GASES
Batteries produce explosive gases. Keep
sparks, flame and cigarettes away, ventilate
when charging or using in enclosed space.
Always shield eyes when working near
batteries.
POISON-CAUSES SEVERE
BURNS Batteries contain sulphuric
acid. Avoid contact with skin, eyes, or
clothing. Antidote: External • Flush with
water. Eyes: Flush with water for 15
minutes and get prompt medical
attention. Internal: Drink large amounts
of water or milk, follow with Milk of
Magnesia, beaten egg or vegetable oil.
Call Physician immediately. Keep out of
the reach of children.
Jump Start
When starting vehicles with another battery and jumper cables, the following instructions should be followed to prevent
sparks at the battery terminals and to prevent damage to other electrical components
on the vehicle.
l. Be sure the ignition key is in OFF
position.
2. Shield eyes. Use safety goggles or
similar eye protection.
3. Place damp cloth across the tops of both
batteries.
4. Connect ends of one cable to positive
( +) terminals of each battery.
5. Connect one end of the other cable to
negative (-) terminal of "good"
battery.
6. Connect other end of cable to engine
bolthead or similar good contact spot
on the vehicle being started (NOT to
negative (-) terminal of battery).
7. To prevent damage to other electrical
components on vehicle being started,
make certain that engine is at idle
speed before disconnecting jumper
cables.
NOTE: Batteries are heavy, weighing
25 lbs and up. Lift them with your legs
rather than your back to prevent muscle
strains, and be careful not to drop them
(possible breakage) nor to spill the
contents (sulfuric acid).
NOTE: Twelve-volt starting motors
can be damaged beyond repair if
connected to a 24-volt power supply (two
12-volt batteries in series, or a 24-volt
motor-generator set), even when
cranking loads are relatively light.
Extensive starting motor damage is more
likely if the starter is connected to a 24volt supply while being subjected to
prolonged heavy cranking loads such as
attempting to start an engine in subzero
temperatures.
TESTING
Tests are made on a battery to
determine the state of charge and also the
condition. The ultimate result of these
tests is to show that the battery is good,
needs recharging, or must be replaced.
If a battery has failed, is low in
charge, or requires water frequently,
good service demands that the reason for
this condition be found. It may be
necessary to follow trouble shooting
procedures to locate the cause of the
trouble.
Refer to Part 31 -01 for charging
system trouble shooting procedures.
Before attempting to test a battery, it
is important to give it a thorough
examination to determine if it has been
damaged. Possible battery damage with
replacement often necessary is indicated
by moisture on the outside of the case
(possible cracked and leaking case) and/
or low electrolyte level in one or more
cells (possible leak or weak cell).
Original equipment batteries
incorporate a single one-piece cover
which completely seals the top of the
battery and the individual cell
connectors. This cover must not be
pierced with test probes to perform
individual cell tests.
TESTS USING CHRISTIE OR
EQUIVALENT
Follow the instructions that come
with the unit.
TESTS USING THE ROTUNDA
BATTERY-STARTER TESTER OR
EQUIVALENT
Battery Capacity Test (Fig. 1)
A high rate discharge tester (Rotunda
Battery-Starter Tester or equivalent) in
conjunction with a voltmeter is used for
this test.
l. Turn the control knob on the Battery
Starter Tester to the OFF position.
2. Turn the voltmeter selector switch to
the 20-volt position.
3. Position the selector switch to
"AMP".
4. Adjust the load control knob until the

5. W i t h the a mmeter rea d ing t h e
required load for 15 seconds, note the
voltmeter reading. Avoid leaving the
high discharge load on the battery for
periods longer than 15 seconds.
6. If the voltmeter reading is 9.6 volts or
more for a 12-volt battery a nd 4.8
volts or more for a 6-volt battery, the
battery has good output capacity and
will r ead il y acce p t a c h arge, if
required. Check the state of charge by
reading the specific gravity of a NonMaintenance Free Battery or the open
circuit voltage of a Maintenance Free
Battery. If the open circuit voltage is
below 12.45, charge the battery according to the battery charge time schedule .
Always disconnect the battery ground
cable when charging the batt.ery.
7. If the voltage reading obtained during
the capaci t y test of a Non Maintenance F ree Ba tter y is below
9.6 volts for a 12-volt battery and 4.8
volts for a 6-volt battery, check the
specific gravity of each cell.
If the difference between any two cells
is m ore t han 50 po in ts (0.050), t he
battery is not satisfactory for service and
should be replaced.
31-02-3
31-02-3
Batteries
If the difference between cells is less
than 50 points (0.050), the battery should
be charged according to the charging
schedule in the Specifications Section.
In some cases the electrolyte level
may be too low to obtain a specific
gravity reading. In such cases, water
should be added until the electrolyte level
just covers the ring in the tiller well, then
charge the battery at 35 amperes for the
maximum charging time indicated in
Specifications for the capacit y of the
battery being tested.
Batteries that are completely discharged
may not accept a fast charge. If this is
found , the bauery should be slowly charged
at 4 amps for (2) hours so the battery will be
capable of accepting a fast charge. A
specific gravity reading taken at this time
will show no change from the original reading and the battery must be charged accord-
ing to the high rate charge time schedule.
8. If the voltage reading obtained during
the capacity test on a Maintenance
Free Battery is below 9.6 volts, check
the open c i rcuit voltage
approximately one minute after the
capacity test. Charge th e battery
according to the charge time schedule
for Maintenance Free Batteries.
9. After the battery has been charged,
repeat the capacity test. If t h e
capacity test battery voltage is still
less than 9.6 volts, replace the battery.
If the voltage is 9.6 volts or more, the
battery is satisfactory for service.
I0. If I h c battery is found to be
discharged only, check for a loose fan
belt, loose electrical connections and
charging system performance.
