E GLOSSARY OF TERMS AND SYMBOLS
BATTERY
Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto's
various electrical circuits.GROUND
The point at which wiring attaches to
the Body, thereby providing a return
path for an electrical circuit; without a
ground, current cannot flow.
CAPACITOR (Condenser)
A small holding unit for temporary
storage of electrical voltage.HEADLIGHTS
Current flow causes a headlight
filament to heat up and emit light. A
headlight may have either a single
(1) filament or a double (2) filament
1. SINGLE
FILAMENT
CIGARETTE LIGHTER
An electric resistance heating
element.2. DOUBLE
FILAMENT
CIRCUIT BREAKER
Basically a reusable fuse, a circuit
breaker will heat and open if too
much current flows through it.
Some units automatically reset when
cool, others must be manually reset.HORN
An electric device which sounds a
loud audible signal.
DIODE
A semiconductor which allows
current flow in only one direction.IGNITION COIL
Converts low±voltage DC current
into high±voltage ignition current for
firing the spark plugs.
DIODE, ZENERA diode which allows current flow in one
direction but blocks reverse flow only up
to a specific voltage. Above that potential,
it passes the excess voltage. This acts as
a simple voltage regulator.LIGHT
Current flow through a filament
causes the filament to heat up and
emit light.
PHOTODIODE
The photodiode is a semiconductor
which controls the current flow
according to the amount of light.LED (LIGHT EMITTING DIODE)
Upon current flow, these diodes emit
light without producing the heat of a
comparable light.
DISTRIBUTOR, IIA
Channels high±voltage current from
the ignition coil to the individual
spark plugs.METER, ANALOG
Current flow activates a magnetic
coil which causes a needle to move,
thereby providing a relative display
against a background calibration.
FUSEA thin metal strip which burns through
when too much current flows through it,
thereby stopping current flow and
protecting a circuit from damage.
FUSIBLE LINK
METER, DIGITAL
Current flow activates one or many
LED's, LCD's, or fluorescent
displays, which provide a relative or
digital display.
FUEL
FUSIBLE LINK
A heavy±gauge wire placed in high
amperage circuits which burns through on
overloads, thereby protecting the circuit.
The numbers indicate the crosssection
surface area of the wires.(for Medium Current Fuse)
(for High Current Fuse or
Fusible Link)MOTOR
A power unit which converts
electrical energy into mechanical
energy, especially rotary motion.

(b) Matlers that require attention when checking:

Noise coming into the radio usually has no harm for
practical use as the noise protection is taken and it
is hardly thinkable for an extremely loud noise to
come in. When extremely loud noise comes into the
radio, check if the grounding is normal where the
antenna is installed.

Check if all the regular noise prevention parts are
properly installed and if there is any installation of
non±authorized parts and non±authorized wiring.

If you leave the radio out of tune (not tuning), it is
easy to diagnose the phenomenon as noise occurs
frequently.
(c) Antenna and noise:
Electronic signal received by the antenna will reach to the
radio transmitting through the core wire of the coaxial
cable. Any noise wave other than radio wave is mixed into
this core wire, that naturally causes noise in the radio and
poor sound quality. In order to prevent these noises from
mixing into the radio, the core wire inside the coaxial cable
is covered with a mesh wire called shield wire. This shield
wire shelters the noise and transmits it to the ground, thus
preventing noise from mixing in. If this shield wire has
grounding failure, that causes noise.
(d) Choke coil and noise:
The choke coil is connected in the rear window defogger
circuit. This is conneted so to prevent noise from mixing
into the radio by making the noise current included in the
power source of the rear window defogger flow to the
ground.

(i) Install the V±bank cover.
3. INSPECT SPARK PLUGS
NOTICE:

Never use a wire brush for cleaning.

Never attempt to adjust the electrode gap on a used
spark plug.

Spark plugs should be replaced every 100,000 km
(60,000 miles).
(a) Remove the high±tension cords set. (See step 2)
(b) Remove the ignition coils.
(c) Inspect the electrode.
Using a megger (insulation resistance meter), measure
the insulation resistance.
Standard correct insulation resistance:
10 MW or more
If the resistance is less than specified, proceed to step (e).
HINT:
If a megger is not available, the following simple method of in-
spection provides fairly accurate results.
(d) Simple Method:
(1) Quickly race the engine to 4,000 rpm 5 times.
(2) Remove the spark plug. (See step (e))
(3) Visually check the spark plug.
If the electrode is dry ... OK
If the electrode is wet ... Proceed to step (f)
(4) Install the spark plug. (See step (i))

3. INSPECT FIELD COIL
(a) Check the field coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
(b) Check the field coil for ground.
Using an ohmmeter, check that there is no continuity be-
tween the field coil end and field frame.
If there is continuity, repair or replace the field frame.
4. INSPECT BRUSHES
Using vernier calipers, measure the brush length.
Standard length: 15.5 mm (0.610 in.)
Minimum length: 10.0 mm (0.394 in.)
If the length is less than minimum, replace the brush holder and
field frame.
5. INSPECT BRUSH SPRINGS
Check the brush spring load.
Take the pull scale reading the instant the brush spring
separates from the brush.
Standard spring installed load:
1.2 kW13.7 ± 19.6 N (1.4 ± 2.0 kgf, 3.0 ± 4.4 lbf)
1.4 kW17.6 ± 23.5 N (1.8 ± 2.4 kgf, 3.9 ± 5.3 lbf)
Minimum spring installed load:
1.2 kW9.8 N (1.0 kgf, 2.2 lbf)
1.4 kW11.8 N (1.2 kgf, 2.6 lbf)
If the installed load is less than minimum, replace the brush
