IDENTIFYING CONNECTORS
In circuit diagrams, the connectors are indicated by symbolic
marks which show the number of their wires and whether they
are male,or female connectors.
(1) Number of connector wires
The number of divisions in the connector diagram indicates
the number of wires. A cross in a division, however, indicates
the position of a guide to prevent improper connection. The
connector shown here, therefore, is a g-wire connector.

(2) Identification of male and female connectors
Connectors drawn with double outer lines are male, and those
with single outer lines are female.
(3) Connector direction
The connector marks show on-vehicle connectors as viewed
from the direction shown here.
(4) Identification of connector terminals
The color codes of a pair of connectors (male and female), if
viewed at their joining surfaces, will appear symmetrical as
illustrated here. When the connectors are connected, their
joining surfaces are put together in the way a book is closed,
so the terminals of identical codes are connected together.
NOTE
The color codes of male and female connectors are not always
identical.
(5) Identification of sealed connectors
Identification of round, sealed connectors (water-proof pin ter-
minal connectors) used in radiator fan motor circuits, turbo
circuits, etc. is accomplished by the same method as
described above.

l A loose horn bracket mounting bolt.
HORN ADJUSTMENT (1) Secure the horn bracket in a vice, and then connect a
battery of the 12 volts.
(2) Sound the horn, and adjust it by turning the adjusting
screw.
0 The sound volume is too low.
Turn the adjusting screw in the “UP” direction within a
range of about 180”, and then set it in position when a
satisfactory sound volume has been obtained.
0 The sound volume is too loud:
Turn the adjusting screw 20” to 30” in the “DOWN”
direction, and then set it in position when a satisfactory
sound volume has been obtained.
0 Horn will not sound:
Turn the adjusting screw slightly in the “UP” direction
until the horn sounds, find a satisfactory sound volume
by continuing to turn the screw within a range of 180”,
and then set the screw in place. If a satisfactory
volume cannot be obtained, replace the horn.
Caution
After the adjustment apply lacquer to prevent the
adjusting screw from becoming loose.

COMPRESSOR - The prime purpose of the compressor is to compress the low pressure refrigerant vapor
from the evaporator into a high pressure, high temperature vapor. The 6 cylinder 6P148 compressor is used.
MAGNETIC CLUTCH is mounted on the compressor providing a convenient way to drive and disengage
compressor in accordance to the cooling needs. CONDENSER is located in front of the radiator. Its function
is to cool the hot, high pressure refrigerant gas causing it to condense into high pressure liquid refrigerant.
RECEIVER DRIER is used to remove any traces of moisture from the refrigerant system. This component
incorporates the sight glass and fusible plug. SIGHT GLASS at the top of the receiver drier is provided as a
diagnostic tool to observe refrigerant flow and observe refrigerant level. THE FUSIBLE PLUG is located on
the receiver drier. Its function is to prevent damage to the air conditioning system in the event that
excessive pressure develops due to condenser air flow being restricted by, for example, leaves, newspaper,
an overcharge of refrigerant, or air in the system. LOW PRESSURE SWITCH prevents damage to the
compressor in case of system loss of refrigerant charge. EXPANSION VALVE - The expansion valve is used
for all applications. Its function is to meter refrigerant into the evaporator in accordance with cooling
requirements. EVAPORATOR COIL is located in the unit and its function is to cool and dehumidify the air
before it enters the vehicle. FREEZE UP CONTROL FIN THERMOSTAT SENSOR is installed at the heater
side of evaporator. The main function of a freeze control is to keep condensate water on the face of the
evaporator coil from freezing and restricting air flow. WATER TEMPERATURE SWITCH - When the
temperature of the radiator coolant became high, this switch functions to stop the compressor and prevent
engine overheating. SERVICE VALVE at the compressor and the discharge line. The valves are used to test
and service the refrigerant system. REFRIGERANT R-12 is used maximum amount 907 g (32 oz.) R-12.
COMPRESSOR OIL is used DENS0 oil 6 maximum amount 110 cc (3.7 U.S.fl.oz., 3.9 Imp.fl.oz.).
