L:FUEL GAUGE SIMPLE CHECKTACHOMETER CHECK
(1)insert paper clip into the engine revolution speed detection
terminal provided in the engine compartment, and connectthe engine tachometer to the inserted paper clip.
Caution
As the tachometer is negative grounded, do not con-
nect battery conversely to prevent damaging transis-tor and diode.
NOTE
For tachometer inspection, use of a fluxmeter-type engine
tachometer is recommended. (Because a fluxmeter onlyneeds to be clipped to the high tension cable.)
(2) Connect the engine tachometer and compare the engine
tachometer and tachometer readings. Replace tachometer
if difference is excessive.

CautionThe engine speed signal output from the engine is
one-third of the actual speed. When the engine speed
is measured, make sure that the engine tachometeris placed in the
2-cylinder range. (The real speed is
indicated.)
Connect a test light to the harness con-nector.
Place the ignition switch in the ON posi-
tion.Check the test light and gauge conditions.

INSPECTION
REED SWITCH CHECK

Use circuit tester to check circuit repeats off/on between termi-\
nals when speedometer shaft turned several times.d
VEHICLES SPEED SENSOR CHECK

(1)Remove the vehicles speed sensor and connect as shownin the illustration, using a
3-10 k&2 resistance.
(2) Use a voltmeter to check for voltage at terminals (2) and
(3) when the pulse generator shaft is turning. (One revolu-
tion is four pulses.)
FUEL GAUGE CHECK
Measure resistance between terminals with circuit tester.

A-6There is noise when starting the engine.
Noise type
Sounds are in pa-
rentheses ( ).
AM, FM:
Ignition noise
(Popping, Snap-
ping,Cracking,
Buzzing)
Otherelectrical
components
Static electricity
(Cracking, Crin-
kling)
Conditions
0Increasing the engine speedcausing the popping sound tospeed up, and volume de-creases.0Disappears when the ignitionswitch is turned to ACC.
-
lDisappears when the vehicle is
completely stopped.Occurs when parts or wir-
Severe when the clutch is en-ing move for some reasonlgaged.and contact metal parts of
the body.
lVarious noises are produced de-pending on the body part of thevehicle.
Due to detachment from
the body of the front hood,
bumpers, exhaust pipe
and muffler, suspension,
etc.
Causel
Mainly due to the
spark plugs.l Due to the enginenoise.
Noise may appear as
electrical components be-
come older.

Repair or replace electricalcomponents.
Return parts or wiring to
their proper position.
Caution
1.Connecting a high tension cable to the noise
filter may destroy the noise filter and shouldnever be done.
2.Check that there is no external noise. Since
failure to do this may result in misdiagnosis
due to inability to identify the noise source,
this operation must be performed.3. Noise prevention should be performed by
suppressing strong sources of noise step
by step.
NOTE
1. Condenser
The condenser does not pass D.C. current, butas the number of waves increases when it
passes A.C. current, impedance (resistanceagainst A.C.) decreases, and current flow is
facilitated. A noise suppressing condenser
which takes advantage of this property is in-
serted between the power line for the noise
source and the ground. This suppresses noiseby grounding the noise component (A.C. or
pulse signal) to the body of the vehicle.
2. Coil
The coil passes D.C. current, but impedance
rises as the number of waves increases relativeto the A.C. current. A noise suppressing coil
which takes advantage of this property is in-
serted into the power line for the noise source,
and works by preventing the noise componentfrom flowing or radiating out of the line.

Ground parts by bonding.
Cases where the problem
is not eliminated by a single
response to one area are
common, due to several
bodypartsbeing
imperfectly grounded.

lWhen the time between songs on a tape is less than three seconds,or when there is a three second period in the middle of a song in
which the volume level is extremely low, the automatic search function
*2may not work properly.
lEnsure that the tape label is not loose, that the tape itself is not deformedand that the tape is tightly wound. Also, tapes of C-120 or greater
length often get caught in the mechanism and should not be used.
