DESCRIPTION

Figure 1—Wire Coding

• The diagrams are to be traced from the source of electricity (the battery positive post) to ground. The ground may be a chassis ground on a certain component (such as an alternator or a starter), or a wire from a component to a chassis or frame ground (such as used on the electronic control module and instrument panei). All grounds are connected to the negative battery post through body and/or angina ground wires and straps.

• Many times the source of the electricity is shown as the ignition switch or the fuse block. This is done to eliminate the confusion that would occur if the entire power distribution was shown in each circuit. For a detailed outline of the power to the ignition switch or the fuse block, refer to the power distribution circuit.

• The ground portion of the circuit (usually circuit 150 or 151) may be shown entirely, or it may refer to the ground distribution circuit in order to avoid confu-sion of listing ail the grounds in one splice on a sin-gle page.

• For ease of diagnosis, ali splices and grounds are identified by number, and all the wires on a common splice or ground are identified by circuit number, size (in mm) and color. Each component or circuit common to s spliced wire is called out by the page number of that circuit. This will help identify and di-agnose multiple electrical problems that could occur in a truck.

• All connectors are shown with their part numbers to save time when ordering these parts.

• Switches are shown in their at rest positions, unless otherwise marked.

TRACING CIRCUITS Figures 1 through 3 are examples of how the wiring

diagrams are laid out., and will be referred to, throughout this description.

In order to trace a circuit on these diagrams, start from the source, the battery. In figure 2, the battery positive

circuit is a 19.0 mm black wire. This wire runs from the battery to the starter motor, and supplies power to the starter motor post.

Once you have determined the source of power to your component, from the Power Distribution Circuit (figure 2), then refer to the individual circuit you are working on for more detail about that circuit. (Figure 3 shows the starting circuit).

In figure 3, the starter motor circuit is shown. This circuit shows the battery feed coming from the Power Distribution page. The cable comes from the battery to the start©? positive post. At the starter post, other circuits such as the generator, ignition switch, and electronic control module are fed.

When the ignition switch is in the start position, power flows from circuit #2 through the switch, to circuit #6. Circuit #6 goes through the clutch switch with an automatic transmission. At the clutch switch the circuit is opened, unless the dutch is depressed.

At the solenoid the current flowing from circuit #6 closes the soiertoid, allowing current to flow from the battery at circuit #1 to the starter motor. The current flowing to the starter motor, causes the starter motor to spin.

BASIC ELECTRICAL CIRCUITS An electrical circuit starts from a supply of electricity

back to a load and then conducts the electricity back to the supply of electricity. There should be a device to open and close the circuit, and a protective device to open the circuit in case too much current is drawn into the circuit by an overload condition. Electrical circuits can be set up as series circuits, parallel circuits or series/parallel' circuits. The circuits in trucks are usually parallel circuits.

WIRING DIAGRAMS 5 WIRING DIAGRAMS 6

path. For example the switch controlling the headlights is at the power end of the circuit while the door switch controlling the domelight completes the ground path.

Relays are remotely controlled switches. They are used in high current circuits and in circuits controlled by sensors.

Relays are designed so that a small current circuit wi!3 he able to control a large current circuit.

CIRCUIT BREAKERS (Figure 7) Circuit breakers are another form of circuit protector.

There are two types of circuit breakers; automatic reset and remote reset.

The automatic reset breaker opens when excess current heats a bimetallic strip, causing the strip to bend and open a set of contacts. Then the strip cools and closes the contacts. So the circuit breaker opens and closes until the excess current condition is corrected or

the circuit is disconnected from the power supply. The remote reset circuit breaker has a heating wire

wound around the bimetallic strip. When an excess current happens, the strip heats, bends, and opens the contacts. Then a small current flows through the heating wire, keeping the strip hot and the contacts open. This type of breaker will stay open until either the power supply is disconnected from the circuit or the breaker is removed from the circuit. Then the breaker can cool and reset.

CIRCUIT LOADS ( F i gu re 7) Circuit loads are the components that use most of the

energy in circuit. The energy converts to motion, light, or heat, l ights, motors, and engine heaters are the most common loads in circuits.

CIRCUIT DIAGNOSIS

A clear understanding of the circuit and a wiring diagram are needed for effective diagnosis. Use a logical sequence of testing to find the trouble. Use the diagnostic tools. After the trouble is fixed, make sure the circuit works correctly.

CIRCUIT MALFUNCTIONS There are three electrical conditions that can cause a

nonworking circuit; an "Open Circuit", a "Short Circuit", or a "Grounded Circuit"

OPEN CIRCUIT (Figure 8) An open circuit occurs whenever there is a break in the

circuit. The break can be corrosion at the connector, a wire broken off in a device, or a wire that burned open from too much current.

SHORT CIRCUIT (Figure 9} A short circuit happens when the current bypasses part

of the normal circuit. This bypassing is usually caused by wires touching, salt water in or on a device such as a switch or a connector or solder melting and bridging conductors in a device.

Figure 7—Circuit Controllers

FUSES (Figure 8) The most common protector in the vehicle circuit is a

fuse. A fuse consists of a fine wire or strip of metal inside a glass tube or plastic housing. The strip melts and interrupts the flow of current in the circuit when there Is an overload caused by an unwanted short or ground. The fuse is designed to melt before the wiring or electrical components in a circuit can be damaged. Naturally, the cause must be located and corrected before the fuse is replaced or the new fuse will also blow.

Since different circuits handle different amounts of current, fuses of various ratings are used. Fuses are rated in amperes. Be sure to replace a blown fuse with a fuse of the connecting rating.

CIRCUIT CONTROLLERS (Figure 7) Circuit controllers consist of switches or relays.

Switches are usually operated by a mechanical means such as a hand or lever. Switches are usually at the beginning of a circuit but can be used to control a ground

Figure 5—Series/Parallel Circuits

FUSIBLE LINK

A fusible link is a section of wire that is usually four gage sizes smaller than the circuit it protects. A special insulation is used that swells when heated by the wire. Fusible links are usually found in the engine compartment harnesses. The function of the fusible link is to melt open when an overload occurs, thus preventing any damage to the circuit.

Figure 6--Circuit Components

Figure 4—Basic Circuits

SERIES CIRCUITS (Figure 4 and 5) In a series circuit, the electrical devices are connected

together to form one current path to and from the power supply. In a series circuit the same current flows through all of the devices.

PARALLEL CIRCUITS (Figure 5) In a parallel circuit, the electrical devices are connected

to form more than one current path to and from the power supply. In a parallel circuit the supply voltage is the same in each current path.

SERIES/PARALLEL CIRCUIT (Figure 5) A series/parallel circuit consists of a single current path

circuit and a circuit with more than one current path to and from" the voltage supply.

CIRCUIT COMPONENTS (Figure 6) The usual circuit path starts at the power supply which

is the battery/generator system. Next in the circuits is the circuit protection component which cars he a fusible link, a fuse, or a circuit breaker. Then the circuit goes to the circuit controller which can be a switch or a relay. From the circuit controller the circuit goes into the circuit load. The circuit load can be one light or many lights in parallel, an electric motor or a solenoid. After the electricity has passed through the load it must return to the power supply via the ground path. The ground path can be a wire in the harness or it could be through the load housing into the body or frame, thus returning the electricity to the power supply. The body and frame are connected by flexible ground straps.

WIRING DIAGRAMS 7

GROUNDED CIRCUIT(Figure 10) A ground circuit is like a short circuit but the current

flows directly into a ground circuit that is not part of the original circuit. This may be caused by a wire rubbing against the f r a m e or body. Sometimes a wire will break and fall against metal that is connected electrically to the ground side of the power supply. A grounded circuit may also be caused by deposits of oil, dirt and moisture around connections or terminals, which provide a good path to ground.

UNPOWERED TEST LIGHT (Figure 12) This tool consists of a 12 volt light with leads. The ends

of the leads usually have alligator clamps, but various kinds of probes, terminal spades, and special connectors are used also.

The unpowered test light is used on an open circuit. One lead of the test light is grounded and the other lead is moved around the circuit to find the open. Depending on the physical layout of the circuit, sometimes it will be easier to start at the power supply and other times it is easier to start at the Circuit load or ground circuit.

POWERED TEST LIGHT (Figure 11) This light is a pencil shaped unit with a self contained

battery, a 1 5 volt light bulb, a sharp probe and a ground lead fitted with an alligator clip.

This test light is used mainly for testing components that are disconnected from the vehicle power supply. The power test light is also useful for testing suspected high resistance points in a circuit such as connectors and ground circuits that are corroded or loose.

JUMPER The jumper is usually a long wire with alligator clamps.

A version of the jumper has a fuse holder in it with a 10 Amp fuse. This will prevent damaging the circuit if the jumper is connected in the wrong way.

The jumper is used to locals opens in a circuit. One end of the jumper is attached to a power source and then the other end is attached to the load in the circuit, i.e.; light, motor. If the load works, try "jumping" to circuit points that are progressively closer to the power supply. When the circuit load stops working, the open has been located.

The jumper is also used to test components in the circuit such as connectors, switches, and suspected high resistance points.

Figure 13 --Ohmmeter

NOTICE: The followmg instruments: Ammeter, Voltmeter, and Ohmmeter, each have a particular application for trouble shooting electrical circuits.

When using a ammeter or voltmeter, and the value being tested is unknown always use the highest scale first and work downward to a midscale reading whenever possible. This will avoid damage to the Instrument.

Never use an ohmmeter in a power circuit, or as a substitute for a vohmeter or ammeter as damage to the instrument will result.

AMMETER (Figure 12 and 15) Disconnect the circuit from the power source before

connecting the ammeter. The ammeter measures the amount of electrical current, amperes, moving through a conductor. The ammeter must be placed in series with the circuit being tested. Be sure that the ammeter's positive terminal is connected to the positive (battery) side of the circuit and is negative terminal to the negative (ground) side of the circuit.

OHMMETER (Figure 13 and 15) The ohmmeter is an instrument designed to indicate

resistance in ohms, it is used to test the condition of a unit disconnected from the circuit.

Ohmmeter Calibration When the ohmmeter probes are connected together, a

circuit is completed causing the meter needle to deflect The needle should read ZERO ohms, if it does not, rotate the CAL or ADJ knob to ZERO the needle.

When the probes are held apart, the needle moves to the maximum (infinite) resistance side of the scale.

The meter is now ready for use. Refer to figure 14 for a typical application of the ohmmeter.

Figure 14—Voltmeter

VOLTMETER (Figures 14 and 15) The voltmeter (properly observed) will give the

technician more information than the ammeter, ohmmeter and test light combined, its application for troubleshooting here is to measure the electrical pressure (voltage) drop in a resistance circuit (figure 14).

Io use a voltmeter for troubleshooting an electrical problem, connect it in parallel with the existing circuit (figure 10). If the voltmeter is connected in series with the circuit being tested, the nature of the circuit would be changed and the reading would have no particular value or use. Connect the meter terminals according to polarity as shown in figure 14.

The dash mounted voltmeter (in the vehicle) should also be observed for monitoring proper operation of the generator battery cranking motor, and cranking circuit. In this application, battery voltage drop can be monitored while the engine is cranking; and after the engine is running, generator output voltage cars be monitored. This can be a valuable first step prior to diagosing other electrical problems.

WIRING HARNESS AND WIRES Every wire is a specific size with colored or striped

insulation that is indicated on the wiring diagrams. Insulation colors help to trace circuits and to make proper connections. Abbreviations and symbols used for indicating wire insulation colors and patterns are as follows: BIK Black BLU Blue BRN Brown PPL Purple CHK Check TR Tracer CR Cross YEL .Yellow GRN Green // Parallel NAT Natura! WHT White SGL Single STR Stripe ORN Orange PNK Pink GR Gray DK Dark

Some wires are grouped and taped together or encased in a split plastic casing. This grouping of wires is called a harness. For some purposes, it is more practical to use a single wire protected by a braided tubing called a loom.

With the low current and voltage levels found in some circuits, it is important that the best possible bond at all wire splices be made by soldering the splices.

Use care when probing the connections or replacing terminals in them, it is possible to short between opposite terminals. If this happens to the wrong terminal part, it is possible that damage may be done to certa in components. Always use jumper wires between connectors for circuit checking. Never probe through the Weather-Pack seals.

When diagnosing for possible open circuits, it is often difficult to locate them by sight because oxidation or terminal misalignment are hidden by the connectors. Merely wiggling a connector on a sensor or in the wiring harness may correct the open circuit condition. This should always be considered when an open circuit is indicated while troubleshooting. Intermittent problems may also be caused by oxidized or loose connections.

METRl-PACK CONNECTORS The Metri-Pack connectors use a pull-to-seat type

terminal, as shown in figure 19. The special tool required to remove the terminal is J-35689-A terminal remover. If removal is attempted with an ordinary pick, there is a good chance that the terminal will be bent or deformed. Refer to figure 19.

WEATHER-PACK CONNECTORS Special connectors known as Weather-Pack connectors

(figure 19) require a special tool J-28742 for servicing. This special tool is required to remove the pin and sleeve terminals. If removal is attempted with an ordinary pick, there is a good chance that the terminal will be bent or deformed. Unlike standard blade-type terminals, these terminals cannot be straightened once they are bent.

Mate sure that the connectors are property seated and all of the sealing rings in place when connecting the leads. The hinge-type flap provides a back-up, or secondary locking feature for terminals. They are used to improve the connector reliability by retaining the terminals if the small terminal lock tangs are not positioned properly.

Molded-on-connectors require complete replacement of the connection. This means splicing a new connector assembly into the harness. Environmental connections cannot be replaced with standard connect ions. Instructions are provided with the Weather-Pack connector and terminal packages.

CIRCUIT MAINTENANCE AND REPAIR

MAINTENANCE AND REPAIR All electrical connections must be kept clean and tight.

Loose or corroded connections may cause a discharged battery, difficult starting, dim lights, and possible damage to the generator and regulator. Wires must bo replaced if insulation becomes burned, cracked, or deteriorated.

To splice a wire or repair one that is frayed or broken always use rosin flux solder to bond the splice and insulating tape to cover all splices or bare wires.

When replacing wire, it is important that the correct size wire be used as shown on applicable wiring diagrams or parts book. Each harness or wire must be held securely in place to prevent chafing or damage to the insulation due to vibration.

Never replace a wire with one of a. smaller size or replace a fusible link with a were of a larger size.

ON-VEHICLE SERVICE

Wiring harnesses are joined by using a multiple plug and receptacle connector block, or a terminal post chassis junction block. In the instrument panel area plastic insulated blade-type connectors and screw-type terminals are used.

Each harness or wire must be held securely in place by clips or other holding devices to prevent chafing of the insulation.

WIRE SIZE Wire size in a circuit is determined by the amount of

current, the length of the circuit and the voltage drop allowed. Wire size is specified using the metric gage. The metric gage describes the wire size directly in cross section area measured in square millimeters.
