5. 8 Wire Harness
The wire. harness of automotive vehicles is the
artery which serves the electrical parts and is a very
important unit. Troubles in the system cause not only
operating difficulties, but sometimes fire as well. It
is wise to refrain from patching the wiring system.
The wire system consists of harness, supplementary
leads, terminals, terminal sleeves, wire nipples, instru-
ment connection and instruments using small units as
connectors. (Refer to Fig.

The wires which make up the wiring system are
gathered together to facilitate wiring. They are con-
tained in the wire harness, and branches are provided
wherever required. For protection and insulation,
cotton knitting, lacquered or waxed cotton net or
vinyl sleeves are used.
When an unfamiliar wiring system must be inspected
and faulty wiring traced, the merits of the wire
harness become clear. In the above example, the one
faulty branch can not be replaced, but repair must
made· by using new wiring.
The wires of the wire harness and other supple-
mentary wires are marked in a color code or tags
of identification are attached to the ends of the wires.

A fuse is installed on the top of the negative
terminal of the battery. This fuse prevents over-dis-
charge of the battery or fire resulting from faulty
electrical parts and ground shorts. However, when
an AC generating coil and selenium rectifier are coup-
led for power source, the selenium rectifying plate is
sometimes broken by high reverse current if the engine
is operated without a fuse, or if the fuse is burned
out.
Breakage of the selenium rectifier can be prevented
by connecting its output terminal directly to ·the bat·
tery. (Refer to Fig.
