WEEM -Starter Motor 8-99
I-
Carbon-pile rheostat
6EL07’ FREE RUNNING TEST
1. Place starter motor in a vise equipped with soft jaws and
connect a fully-charged 12-volt battery to starter motor as fol-
lows :
2. Connect a test ammeter (loo-ampere scale) and carbon pile
rheostat in series with battery positive post and starter motor
terminal.
3. Connect a voltmeter (16volt scale) across starter motor.
4. Rotate carbon pile to full-resistance position.
5. Connect battery cable from battery negative post to starter
motor body.
6. Adjust rheostat until battery voltage shown on the voltme-
ter reads 1 IV.
7. Confirm that the maximum amperage is within the stand-
ard value and that the starter motor turns smoothly and
freely.
Standard value : Current
Speed Max. 90A
Min. 3,000 rpm
RETURN TEST OF MAGNETIC SWITCH
1. Disconnect field coil wire from “M” terminal of magnetic
switch.
2. Connect a 12V battery between M-terminal and body.
Caution
This test must be performed quickly (in less than 10 sec-
onds) to prevent coil from burning.
3. Pull pinion out and release. If pinion quickly returns to its orig-
inal position, everything is in order. If it doesn’t, replace mag-
netic switch.

IGNITION SYSTEM-General Information
IISTRIBUTOR
Vacuum controller
lEL153
IGNITER OPERATION
(1) When the signal rotor revolves a projection inside the signal rotor alternately moves away from and faces
towards the core detector inside the igniter.
(2) When the projection is separated from the core, an oscillating electrical circuit begins to oscillate, and when it
faces, magnetic flux issuing from the core moves across the inside of the signal rotor, so when loss increases,
oscillation ceases.
(3) This oscillation introduces power to the oscillation detector circuit, and after output is amplified it drives the
power transistor. During oscillation (when the projection and core are apart) electricity flowing through the
ignition coil and when oscillation stops (when the projection and core are facing) the electric current is inter-
rupted.
(4) The electrical detection circuit, in preventing excessive electrical flow to the power transistor, protects the
transistor.

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.

(2) Apply battery voltage (through the test light) to the gauge
unit side terminal.
(3) Check to be sure that the test light switches OFF when the
engine is stopped, and that it flashes while the engine is
running.

(1) Connect a voltmeter for testing.
(2) Turn the ignition key to the ON position.

INSPECTION REED SWITCH
Using an ohmmeter, check that continuity and discontinuity
alternate between terminals 1 and 2 four times at every
rotation of the shaft of the speedometer cable connection.

Check to be sure that buzzer sounds when the battery’s
positive (+) terminal is connected to terminal 2 and the
battery’s negative (-) terminal is connected to terminal 1.
