b.Inspection
-Fuel meter
Connect the fuel gauge to form a circuit with the
resisters as shown Fig.10-6 and check to see if
the gauge pointer swings to each position: F.1/2
and E by changing the resistance value.
If it does not,change the gauge assembly.
Fig.10-6
-Fuel gauge sensor(variable resistor)
Check each resistance value with a tester at each
float position as shown in Fig.10-7.if the
measured values are deviated from respective
specified values,replace the sensor assembly.
Note:
1) Figures in parentheses are reference value
2) Inspect each position in order F to E
3) Read values in three minutes.
1.4.Thermometer
a. Construction
This is the same moving magnet type meters as
the fuel gauge.As the coolant temperature
becomes higher,the resistance in the thermo
unit(sensor) become lower,which results in
more current to the meter circuit and swinging
the meter pointer to the high temperature side
on the scale.Of course,as the coolant
temperature become lower,everything acts in
reverse.
b. Inspection
Normally the thermometer resisters higher
values as the coolant temperature rises after the
engine is running.If it does not,check the wiring
first.If the wiring is normal.Replace assembly.

2. STARTER SWITCH
(1) Removal
a. Remove the dash cover(Upper)
b. Remove the ring nut holding the starter switch
using a conventional screw driver.
c. Pull out the key switch as shown in Fig.10-8
