SIGHT GLASS REFRIGERANT LEVEL
TEST
M1552008400378
1. Start the engine.
2. Operate the air-conditioner, and then set the
temperature to maximum cooling.
3. Hold the engine speed at 1500 r/min.
4. Check the refrigerant level (bubble state) through
the sight glass.
CAUTION
Use the low-pressure service valve.
NOTE: Use the refrigerant recovery station to
charge the specified refrigerant because you can
not calculate the amount of the refrigerant
properly with the sight glass.
MAGNETIC CLUTCH TEST
M1552008500405
1. Disconnect the magnetic clutch connector to the
magnetic clutch.
2. Connect positive battery voltage directly to the
connector for the magnetic clutch.
3. If the magnetic clutch is normal, there will be a
"click." If the pulley and armature do not make
contact ("click"), there is a malfunction.

DUAL PRESSURE SWITCH CHECK
M1552010400320
1. Remove the dual pressure switch connector and
connect the high/low pressure side terminals
located on the harness side as shown in the
illustration..
2. Install a gauge manifold to the high-pressure side
service valve of the refrigerant line. (Refer to
P.55-98 , P.55-99 .)
3. When the high/low pressure sides of the dual
pressure switch are at operation pressure (ON)
the resistance should less than two ohms
between the terminals. If open circuit, replace the
switch.
