Symbols
Ground - "G"
This symbol means the end ol
the wire is attached (grounded) Ito the car frame or to a metal I
part connected to the frame. \i oro,|

Switches
These switches move
together; the broken straight
line between them means the,
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 frame or to a metal
part connected to the frame.
This symbol represents
the bus inside a ground
connector. The dots I
i:l*,':1,'^:*,:"

r"L I I I
terminals connect to.
The ground symbol (large dot)
is the connection between the
bus and metal (grounded) part
of the car.
Terminals - "T"

Solid-state
Fuses
This means power is supplied
when the ignition switch is in ON (ll).
Current rating
Diodes
A rectifier diode works like a one
way valve. lt allows current to
llow only in the direction of the
arrow.
A Zener diode blocks reverse
current at normal voltages just like
a rectifier diode. At high voltages.
however, a Zener diode allows
current to f low in reverse
oo
Each "T" lerminal (ring type)
is numbered for reference and
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interference) shielding
around a wire. The
shielding is always
connected to ground.
