REPLACEMENT OF BRUSHES AND SPRINGS
1. Brushes that are worn beyond limit line, or are oil-soaked,
should be replaced.
2. When replacing field coil brushes, crush worn brush with pli-
ers, taking care not to damage pigtail.
3. Sand pigtail end with sandpaper to ensure good soldering.
4. Insert pigtail into hole provided in new brush and solder it.
Make sure that pigtail and excess solder do not come out onto
brush surface.
5. When replacing ground brush, slide the brush from brush
holder by prying retaining spring back.
TESTING ARMATURE
TESTING ARMATURE FOR SHORT-CIRCUIT
1. Place armature in a growler.
2. Hold a thin steel blade parallel and just above while rotating
armature slowly in growler. A shorted armature will cause
blade to vibrate and be attracted to the core. Replace shorted
armature.
TESTING ARMATURE FOR GROUNDING
Check the insulation in the space between the segments of the
commutator and the armature and coil core. If there is no conduc-
tivity this is normal.
CHECKING CIRCUIT BREAK BETWEEN ARMATURE AND COIL
Check conductivity between each segment. If there is conductiv-
ity this is normal.

8-112 IGNITION SYSTEM - Service Adjustment Procedures
CHECKING NEGATIVE PRESSURE ADVANCE EQUIPMENT
1. Set the timing light.
2. Start the engine and allow it to idle.
3. Pull out the vacuum hose from vacuum controller and attach
vacuum pump to nipple.
4. Check the advance while slowly applying negative pressure to
the vacuum pump. If the advance is smooth when accompa-
nying the increase in negative pressure, this is normal.

5. If the malfunction indicators above are confirmed, dismantle

6. Allow the engine to idle and then turn the ignition switch to
OFF.
7. Remove the vacuum pump and attach the vacuum hose to the
vacuum controller nipple.
8. Remove the timing light.
SPARK PLUG CABLE TEST NWGIGB
Hold the spark plug cable about 6-8 mm (.24-.31 in.) away from
engine proper (grounding portion such as cylinder block) and crank
engine to verify that sparks are produced.
SPARK PLUG TIEST NOUGIHB
Connect the spark plug to the high tension cable, ground outer
electrode (main body), and crank engine. In the atmosphere, only
short sparks are produced because of small discharge gap. If the
spark plug is good, however, sparks will occur in discharge gap
(between electrodes). In a defective spark plug, no sparks will
occur because of leak of insulation puncture.

8430 METERS AND GAUGES - Service Adjustment Procedures.
SERVICE BJUSTMENT. PROCEDURES
SPEEDOMETER INSPECTION NOSHIAA
I. Adjust tire inflation pressure to the standard value. (Refer
to’GROUP 22 WHEELS AND TIRES-General Specifications)
2. Use speedometer tester to make sure that the speedome-
ter indication error is within the standard value.
Standard value :

Caution
1 When using a speedometer tester to inspect the
speedometer, be sure to chock the non-drive wheels
to prevent the vehicle from moving. Also be sure to
set the transfer shift lever to “2H”.
2 If there is a special regulation for speedometer
indication error in the area where the ‘vehicle is
operated, be sure to meet the requirement of the
regulation.
TACHOMETER INSPECTION NOBHIBA
Connect a tach-dwell meter, and then compare the meter
readings at various engine speeds with the values indicated on
the tachometer.
Standard value:
1,000 r/min
3,000 r/min
5,000 r/min f 100 r/min
2150 r/min
&250 r/min
Tgch-dwell meter Caution
The tachometer is the negative-ground type, and therefore
should not be connected in reverse polarity to the battery.
If the tachometer is connected in reverse polarity, the
transistors and diodes will be damaged.

r
(harness side) 16W834
Stopper (upper)
FUEL GAUGE SIMPLE TEST NOEHICE
(1) Disconnect, from below the vehicle, the wiring connector
from the fuel gauge unit.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be
sure that the test light flashes and the fuel
gauge indicator moves.
(5) If both the test light and gauge operate, the circuit to the
gauge unit is normal and the gauge unit itself is faulty.
If the test light flashes but the gauge does not operate, the
gauge is faulty.
If neither the test light nor the gauge operates, the fuel
gauge circuit is faulty.
FUEL GAUGE UNIT INSPECTION NOEHIIF
To check the fuel gauge unit, first remove it from the fuel tank.
For detailed information concerning installation of the fuel
gauge unit, refer to GROUP 4, FUEL SYSTEM - Fuel Tank.
FUEL GAUGE UNIT FLOAT POSITION CHECK
Check to be sure that the height of the fuel gauge float
(relative to the center part of the fuel gauge unit) is within the
standard value range when the float is at the “F” position
(upper limit) and “E” position (lower limit).
Standard value:
A 29.7-34.7 mm (1.170-I .366 in.)
B 183.8-185.8 mm (7.236-7.315 in.)
FUEL GA&E UNIT RESISTANCE CHECK
Confirm that the resistances when the float of the fuel gauge
unit is at the “F” position (top) and the “E” position (bottom)
are within the standard value ranges.
Standard value:
Float position “F” point 14.9-19.1 IR c
Float position “E” point 113.5-126.5 IR’
WATER TEMPERATURE GAUGE SIMPLE T,5$2
(1) Disconnect the wiring connector from the water tempera-
ture gauge unit inside the engine compartment.
(2) Ground the connector at the harness through a test light.
(3) Turn the ignition key to the ON position.
(4) Check to be sure that the test light flashes and the water
temperature gauge indicator moves. ,
