CHECKING
(1) Oil Pressure Switch
(Reference)
•
If you can prepare a variable DC power supply (output
voltage range: 10V - 20 V), check the IC regulator as follows.
Ie Regulator
1. Connect the discrete IC regulator with a variable DC power
supply, voltmeter, lamp, etc., as shown in the figure.
("SW
1 If and "SW2" must be turned off.)
2. Setthe variable DC power supply at 12 V.
3. Turn on "SW,". Check that "l1" (used in place of the charge
lamp)
is lit up brightly and that "l2" (used in place of the
rotor coil) is also lit up.
4. Then, with "SW," turned on, turn on "SW2".
Check
that "ll" is turned off, but that "L2" remains lit.
5. With both "SW
"
and "SW2" turned on, step up the voltage
of the variable
1
De power supply gradually from 12 V and
check that lamp "L2" turns off when the voltage reaches the
level of 14.5 ± 0.3 V at 25°C (77 OF) while lamp "L," remains
off .
• IMPORTANT
• Do
not mistake terminal "16" for terminal "L" or you may
destroy the Ie regulator.
•
If terminals "16" and ilL" of the Ie regulator touches each
other.
the regulator may be damaged. Use the specified
connectors
for wiring.
• The fin does not serve as terminal "E", For connection of
terminal "E" refer to the note in the figure above.

Oil Pressure Indicator Lamp
1. Disconnect the 1 P connector from the oil pressure switch.
2. Turn the main switch key to the "ON" position, and connect
a jumper lead
from the connector terminal to the chassis.
3. If the oil pressure indicator lamp on the main panel does not
light, the bulb or wiring harness is faulty.
Oil Pressure Switch Continuity
1. Disconnect the 1 P connector from the oi I pressu re switch.
2. Using an ohmmeter, check that there is continuity between
the switch terminal and chassis when the engine is stopped.
3. If there is no continuity, the oil pressure switch is faulty.
4. Start the engine. and check that there is no continuity
between the switch terminal and the chassis.
5. If there is continuity, the oil pressure switch is faulty .
• IMPORTANT
• Before
performing the oil pressure switch continuity, be
sure
to check that the engine oil pressure is more than
allowable limit.
