Circuit Schematics
Each schematic reoresents one circuit.
A circuit's wires and components are
arranged to show current flow, from
power at the top of the page, to ground,
at the bottom.
Other circuits may share power or ground
terminals or wiring with the circuit shown.
A wire that connects one circuit to
another, lor example, is cut short and has
an arrowhead at the end of it pointing in
the direction of current flow. Next to the
arrowhead is the name ol the circuit or
component which shares that wiring. To
quickly check shared wiring, check the
operation of a component it serves. lf that
component works, you know the shared
wiring is OK.
All connectors are numbered (C709,
C416, etc.). Below each connector
number (except those for components)
is the number of a ohoto in the back
of the book showing the connector's
location on the car. Connector cavities
are also numbered. The numbering
sequence begins at the top left corner
of the connector as seen from eilher of
the viewpoints shown on page E.
Disregard any numbers molded into the
connector housing.
Wires are identif ied by the abbreviated
names of their colors; the second color is
the color of the stripe. Wires are also
identif ied by their location in a connector.
The number "2" next to the male and
female wire terminals at C416, for
example, means those terminals join in
cavity 2 of connector C41 6.
A complete description of schematic
symbols begins on page @.

Symbols
Ground - "G"
This symbol means the end of
the wire is attached (grounded) Ito the car frame or to a metal Ipart connected to the f rame. \I orol
,
Each wire ground (G) ," -/numbered for reference.
Q,(Switches
These switches move
together; the broken straight
line between them means thev
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted, all switches are shown
in their normal (rest) position,
with power off .
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car f rame or to a metal
part connected to the f rame.
This symbol represents
the bus bar inside a ground
connector. The dots a

Solid-state
Fuses
This means power is supplied
when the ignition switch is in ON (ll).
Diodes
A rectifier diode works like a one
way valve. lt allows current to
flow only in the dlrection of the
arrow.
A Zener diode blocks reverse
currenl at normal voltages just like
a rectifier diode. At high voltages,
however, a Zener diode allows
current to flow in reverse.
Q,(
Each 'T" terminal (ring type)
is numbered for reference ano
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interf erence) shielding
around a wire. The
shielding is always
connected to ground.

Troubleshooting Tests
Testing for Voltage Drop
Wires, connectors, and switches are designed
to conduct current with a minimum loss of
voltage. A voltage drop of more than one volt
indicates a oroblem.
1. Place the digital volvohmmeter (DVOM) in
the appropriate DC volts range. Connect
the positive lead to the end of the wire
(or to the connector or switch) closest to
the battery.
Connect the negative lead to the other
end of the wire (or the other side of the
connector or switch).
Turn on the components in the circuit.
The DVOM will show the difference
in voltage between the two points. A
difference, or drop, of more than one
volt indicates a oroblem. Check the
circuit for loose, dirty, or bent terminals.

'p;
t;tTesting tor a Short to Ground with a Test
Light or DVOM
1. Remove the blown fuse and disconnect
the load.
2. Connect a test light or digital volvohmmeter
(DVOM), switched to the appropriate DC
volts range, across the fuse terminals to
make sure voltage is present. You might
have to turn the ignition switch to ON;
check the schematic to see.

Disconnect theload here.
SOLENOID
Beginning near the f use box, wiggle the
harness. Continue this at convenient ooints
about six inches apart while watching the
test light or DVOM.
Where the test light goes off, or the DVOM
voltage drops to zero, there is a short to
ground in the wiring near that point.
NOTE: Always use a DVOM on high
impedance crrcuits. A test light may not
glow (even with battery voltage present).
