The first letter indicates the basic wire color and the.
second letter indicates the color of the stripe.

DISTINCTION
OF
MALE
AND
FEMALE
CONNECTORS
Male and female connectors are distinguished by shape
of their internal pins.
(a) All connectors are shown from the open end, and
the lock is on top.
(b) To pull apart the connectors, pull on the connector
itself, not the wires.
HINT: Check to see what kind of connector you are
disconnecting before pulling apart.

NOTICE:
1.

Remove
and
insert
straight

out
without

Twisting
could

checked
by
a

BODY ELECTRICAL SYSTEM — General Information
Check for Voltage
(a) Establish conditions in which voltage is present
the check point.
Example:
|- Ignition switch and switch 1 (SW1) on.
©- Ignition switch, switch 1 (SW1) and relay
(switch 2 (SW2) off).
{b) Using a voltmeter, connect the negative (-) lead
a good ground point or negative (-) battery tei
nal and the positive (+) lead to the connector
component terminal. This check can be done with
test bulb instead of a voltmeter.
Check for Continuity and Resistance
(a)
Disconnect
the
battery
terminal
or
wire
so
there
no
voltage
between
the
check
points.
{b)
Contact
the
two
leads
of
an
ohmmeter
to
each
the check
points.
If
the
circuit
has
diodes,
reverse
the
two
leads
and
check
again.
’
When
contacting
the
negative
(~)
lead
to
the
diode
pos-
itive
(+)
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.
HINT:
Specifications
may
vary
depending
on
the
type
of
tester,
so
refer
to
the
tester's
instruction
manual
before
performing
the
inspection.

(d)
Disconnect

while
watching the test bulb.
The short lies between the connector where the
test bulb stays lit and the connector where the
bulb goes out.
(e) Find the exact location of the short by lightly
shaking the problem wire along the body.

HINT:
If

when

the

‘When
the
switches
are
set,
current
is

from

After

because

made
between

and
the
body
ground,
terminal
4 and the body ground of the running
light relay, the taillight
contro! relay and head}
control relay are turned on, so the running
lights will come on.
It is still low-beam headlights which light up, but they are grounded using a special resistor so
they are dimmed to approx. 80% of the normal intensity.
LIGHT CONTROL SWITCH “HEAD”
When the switch is set, continuity is made between terminal 5 and the body ground, and termir
and the body ground of the running light relay. Also, because the continuity is made bi
terminal 6 and the body ground, and terminal 4 and the body ground of the running light relay at
times, the taillights and headlights light up.
HINT: When the headlight dimmer switch is set to “Hi”, continuity is made between terminal 16
the running light relay and the body ground. Also, because continuity is made between terminal
of the running light relay and the body ground, the headlight dimmer relay is turned on. Then
headlights go on at the high beam. \
HEADLIGHT DIMMER SWITCH “FLASH”
When the switch is set, continuity is made between terminal 7 and the body ground, and termi
16 and the body ground of the running light relay. Also, because the continuity is made e
terminal 6 and the body ground, and terminal 17 and the body ground of the running light relay,
headlights flash. |
ENGINE STOPS (IGNITION SWITCH “ON”)
When the engine is stopped, because the continuity between terminal 6 and terminal 13 of the
