This figure illustrates a complex switch. The continuity
between terminals at each position is as indicated in the
table below.4th stage
CHECKING RELAYS1. When current flows through the coil of a relay, its core
is magnetized to attract the iron piece, closing (ON) the
contact at the tip of the iron piece. When the coil current
is turned off, the iron piece is made to return to its original
position by a spring, opening the contact (OFF).
2.By using a relay, a heavy current can be turned on and
off by a switch of small capacity. For example, in the circuit
shown here, when the switch is turned on (closed), current
flows to the coil of the relay. Then, its contact is turned
on (closed) and the light comes on. The current flowingat this time to the switch is the relay coil current only
and is very small.3. The relays may be classified into the normal open type
and the normal close type by their contact construction.
NOTE
The deenergized state means that no current is flowing
through the coil and the energized state means that current
is flowing through the coil.

State of fuse blown due to thermal fatigue
Z1660236When a normal close type relay as illustrated here is
checked, there should be continuity between terminals
(1) and (2) and between terminals 3 and 4 when the relay
is deenergized, and the continuity should be lost betweenterminals 3 and 4 when the battery voltage is applied
to the terminals
1 and 2. A relay can be checked in this
manner and it cannot be determined if a relay is okay
or faulty by checking its state only when it is deenergized
(or energized),
CHECKING FUSESA blade type fuse has test taps provided to allow checking
of the fuse itself without removing it from the fuse block. Thefuse is okay if the test light comes on when its one lead is
connected to the test taps (one at a time) and the other lead
is grounded. (Change the ignition switch position adequatelyso that the fuse circuit becomes live.)
CAUTIONS IN EVENT OF BLOWN FUSE
When a fuse is blown, there are two probable causes as follows:One is that it is blown due to flow of current exceeding its
rating.The other is that it is blown due to repeated on/off current
flowing through it. Which of the two causes is responsible
can be easily determined by visual check as described below.(1) Fuse blown due to current exceeding rating
The illustration shows the state of a fuse blown due to
this cause. In this case, do not replace the fuse with a
new one hastily since a current heavy enough to blow
the fuse has flowed through it. First, check the circuit
for shorting and check for abnormal electric parts. Only
after the correction of such shorting or parts, fuse of the
same capacity should be used as a replacement. Never
use a fuse of larger capacity than the one that has blown.
If such a fuse is used, electric parts or wirings could be
damaged before the fuse blows in the event an overcurrent
occurs again.(2) Fuse blown due to repeated current on/off
The illustration shows the state of a fuse blown due to
repeated current on/off. Normally, this type of problem
occurs after fairly long period of use and hence is less
frequent than the above type. In this case, you may simplyreplace with a new fuse of the same capacity.

BAlTERY VISUAL CHECK (1)
The battery contains a visual test indicator which gives blue
signal when an adequate charge level exists, and white signal
when charging is required.
BAlTERY VISUAL CHECK (2)
Make sure ignition switch is in Off position and all battery
feed accessories are Off.
1.Disconnect ground cable from battery before disconnecting
(+) cable.
2. Remove battery from vehicle.
CautionCare should be taken in the event battery case is
cracked or leaking to protect hands from the electro-
lyte. A suitable pair of rubber gloves (not the house-hold type) should be worn when removing battery
by hand.
3.Inspect battery carrier for damage caused by loss of acid
from battery. If acid damage is present, it will be necessaryto clean area with a solution of clean warm water and
baking soda. Scrub area with a stiff bristle brush and wipe
off with a cloth moistened with ammonia or baking soda
in water.
