Power supply : 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 iq turned on (closed),
current flows to the coil of the relay. Then, its contact

CAUTIONS IN EVENT `OF BLOWN FUSE `- -
State of fuse blown due to overcurrent
When a fuse is blown, there are two, probable cai& ai
follows: One is that it'is blown dire 10 flow # curr,,bt `exceeding
its rating. The other is that it is blowti dtie$e'.re@@ed on/off
current flowing through it. Which of thetwo ca$e$ &.resppnsi-
ble can be easily determined by visual che'i=k as .de&nbed
below. 2 ii
(1) Fuse blown due to current exceeding' rating
The illustration shows the state of $fu$e bldwn due ta
1600237
this cause. In this case, do not r&lace ttie fuse with
a new one hastily since a current heavy :enough to,,-blow
the fus&`has flowed through it, First, check the &cuit
use only a fase of the for shot=& and check for abnormal,
electric parts. After correcting shorts dr replacing parts,
use only. a fuse of the same capacity as a replacement.
Never use a fuse of lager 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 0vRrcurrent occurs again.
(2) Fuse blown due to repeated current on/off ,
State of fuse blown due to thermal fatigue The illustration shows the state of a fuse blown due to'
repeated current on/off. Normally, i this Q$e of problem
occurs after a fairly long period of use and is less frequent
than the above type. In this casi~+,~ simply repj@e with
.'
a new fuse of the same capacity. '

10 GENERAL - How to Diagnose
CABLES AND WIRES CHECK ;
1. Check connections for looseness, rust and stains.
2. Check'terminals and wires for corrosion by battery electro-
lyte, etc.
3. Check terminals and wires for open circuit or impending
open circuit.
4. Check wire insulation and coating for damage, cracks
and degrading.
5. Check ,conductive parts of terminals for contact with other
metallic parts (vehicle body and other parts).
6. Check grounding parts to verify that there is complete
continuity between attaching bolt(s) and vehicle body.
7. Check for incorrect wiring.
8. Check that wirings are clamped to prevent contact with
sharp corners of the vehicle body, etc. or hot parts (exhaust
manifold, pipe, etc.).
9. Check that wirings are clamped .firmly to secure enough
clearance from the fan pulley, fan belt, and other rotating
or moving parts.
10. Check that the wirings between the fixed parts such as
the vehicle body and the vibrating' parts such as the engine
are made with adequate allowahce for vibrations.
BATTERY HANDLING
When checking or servicing does not require `power %om
the on-vehicle battery, be sure to disconnect the cable from
the battery (-) terminal. This is to prevent problems that
could be caused by a short circuit. Disconnect the (k) terminal
first and reconnect it last.

GENERAL ELECTRICAL SYSTEM CHECK
Power supply A circuit consists of the power supply, switch, relay, load,
-r ground, etc. There are various methods to check a circuit
including an overall check, voltage check, short-circuit check,
and continuity check. Each of # these methods is briefly
described in the following:
1. VOLTAGE CHECK
(1) Ground one lead wire of the test light. If a voltmeter
is used instead of the test light, ground the grounding
side lead wire.
(2) Connect the other lead wire of the test light to the
power side terminal of the switch connector. The
test light should come on or the voltmeter should
indicate a voltage.
(3) Then, connect the test light or voltmeter to the motor
connector. The test light should not come on, or
the voltmeter should indicate no voltage. When the
switch is turned on in this state, the test light should
Motor come on, or the voltmeter should indicate a voltage,
with motor starting to run.
(4) The circuit illustrated here is normal. If there is any
problem, such as the motor failing to run, check volt-
ages beginning at the connector nearest to the motor
until the faulty' part is identified.

2. SHORT-CIRCUIT CHECK
Because the fuse has blown, it is probable that there is a short circuit. Follow the procedures
below to narrow down the short-circuit location.
Take out the blown fuse and connect the test light to the
disconnected terminal (switch: OFF).
Short-circuit between the fuse block and the switch A. 1
Switch ON the switch. (The test light illuminates but the illumination
light does not.)

3. CONTINUITY CHECK
Self power test light (1) When the switch is in the OFF position, the self power
(or ohmmeter) test light must illuminate or the ohmmeter should read
0 ohm, only when the terminals 1 and 2 are
J interconnected.
(2) When the switch is the ON position, the self power
test light should come on or the ohmmeter should
read 0 ohm, only when the terminals 3 and 4 are
interconnected.
