HOW TO USE THIS MANUAL B
This manual provides information on the electrical circuits installed on\
vehicles by
dividing them into a circuit for each system.
The actual wiring of each system circuit is shown from the point where t\
he power
source is received from the battery as far as each ground point. (All c\
ircuit
diagrams are shown with the switches in the OFF position.)
When troubleshooting any problem, first understand the operation of the \
circuit
where the problem was detected (see System Circuit section), the power\
source
supplying power to that circuit (see Power Source section), and the ground poin\
ts
(see Ground Point section). See the System Outline to understand the c\
ircuit
operation.
When the circuit operation is understood, begin troubleshooting of the p\
roblem
circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing
sections to find each part, junction block and wiring harness connectors, wiring\
harness and wiring harness connectors, splice points, and ground points \
of each
system circuit. Internal wiring for each junction block is also provided for b\
etter
understanding of connection within a junction block.
Wiring related to each system is indicated in each system circuit by arr\
ows
(from__, to__). When overall connections are required, see the Overall\
Electrical
Wiring Diagram at the end of this manual.

The
”Current Flow Chart” section, describes which parts each power source (fuses, fusible links\
, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the condition\
s when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power so\
urce, the power source system must be fully
understood.

The chart below shows the route by which current flows from the battery \
to each electrical source
(Fusible Link, Circuit Breaker, Fuse, etc.) and other parts.

C TROUBLESHOOTING
VOLTAGE CHECK
(a) Establish conditions in which voltage is present at the check
point.
Example:[A] – Ignition SW on
[B] – Ignition SW and SW 1 on
[C] – Ignition SW, SW 1 and Relay on (SW 2 off)
(b) Using a voltmeter, connect the negative lead to a good ground point or negative battery terminal, and the positive lead to the
connector or component terminal.
This check can be done with a test light instead of a voltmeter.
CONTINUITY AND RESISTANCE CHECK
(a) Disconnect the battery terminal or wire so there is no voltage
between the check points.
(b) Contact the two leads of an ohmmeter to each of the check points.
If the circuit has diodes, reverse the two leads and check
again.
When contacting the negative lead to the diode positive side
and the positive lead to the negative side, there should be
continuity.
When contacting the two leads in reverse, there should be no
continuity.
(c) Use a volt/ohmmeter with high impedance (10 k Ω/V
minimum) for troubleshooting of the electrical circuit.

E GLOSSARY OF TERMS AND SYMBOLS
BATTERY
Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto’s
various electrical circuits.GROUNDThe point at which wiring attaches to
the Body, thereby providing a return
path for an electrical circuit; without a
ground, current cannot flow.
CAPACITOR (Condenser)A small holding unit for temporary
storage of electrical voltage.HEADLIGHTSCurrent flow causes a headlight
filament to heat up and emit light. A
headlight may have either a single
(1) filament or a double (2) filament
1. SINGLE
FILAMENT
CIGARETTE LIGHTER
An electric resistance heating
element.2. DOUBLE
FILAMENT
CIRCUIT BREAKERBasically a reusable fuse, a circuit
breaker will heat and open if too
much current flows through it.
Some units automatically reset when
cool, others must be manually reset.HORNAn electric device which sounds a
loud audible signal.
DIODEA semiconductor which allows
current flow in only one direction.IGNITION COILConverts low–voltage DC current
into high–voltage ignition current for
firing the spark plugs.
DIODE, ZENER
A diode which allows current flow in one
direction but blocks reverse flow only up
to a specific voltage. Above that potential,
it passes the excess voltage. This acts as
a simple voltage regulator.LIGHTCurrent flow through a filament
causes the filament to heat up and
emit light.
PHOTODIODEThe photodiode is a semiconductor
which controls the current flow
according to the amount of light.LED (LIGHT EMITTING DIODE)
Upon current flow, these diodes emit
light without producing the heat of a
comparable light.
DISTRIBUTOR, IIAChannels high–voltage current from
the ignition coil to the individual
spark plugs.METER, ANALOG
Current flow activates a magnetic
coil which causes a needle to move,
thereby providing a relative display
against a background calibration.
FUSE
A thin metal strip which burns through
when too much current flows through it,
thereby stopping current flow and
protecting a circuit from damage.
FUSIBLE LINK
METER, DIGITALCurrent flow activates one or many
LED’s, LCD’s, or fluorescent
displays, which provide a relative or
digital display.
FUEL
A heavy–gauge wire placed in high
amperage circuits which burns through on
overloads, thereby protecting the circuit.
The numbers indicate the crosssection
surface area of the wires.(for Medium Current Fuse)
(for High Current Fuse or
Fusible Link)MOTOR A power unit which converts
electrical energy into mechanical
energy, especially rotary motion.
