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

HINT:
To remove the terminal for this type of connec-
tor, please construct and use the special tool or like ob-
ject shown on the left .

DISCONNECT TERMINAL FROM CONNECTOR
(a)
Using the special tool, raise the retainer up to the tem-
porary lock position .
HINT:
The needle insertion position varies according to
the connector's shape (number of terminals, etc .), so check
the position before inserting it.

Replacement of Fuse
HINT: If replacing the fuse, be sure to replace it with a
fuse with and equal amperage rating .
NOTICE:
1 .
Turn off all electrical components and the ignitio
switch before replacing a fuse
. Do not exceed the fu
amperage rating .
2 .
Always use a fuse puller for removing and insertin
a fuse
. Remove and insert straight in and out witho
twisting . Twisting could force open
the terminals to
much, resulting in a bad connection.
If a fuse continues to blow, a short circuit is indicated
. Th
system must be checked by a qualified technician
.

Check for Voltage
(a)
Establish conditions in which voltage is present at the
check point.
Example :
OA -
Ignition switch on.
© - Ignition switch and switch 1 (SW 1) on
.
© - Ignition switch, switch 1 (SW 1) and relay
on (switch 2 (SW2) 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 compo-
nent terminal
. This check can be done with a test bulb
instead of a voltmeter .
Check for Continuity and Resistance
(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 .
m
0
If the circuit has diodes, reverse the two leads and check
again.
When contacting the negative
(-)
lead to the diode posi-
tive (+) 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
.

Use a tester with a power source of 3 V or greater to
overcome the circuit resistance.
