Diode
Test
NOTE: The diode is designed to pass current in one
direction while blocking it in the opposite direction.
Use an analog ohmmeter, or a digital ohmmeter
equipped with a diode tester.
Check for current flow in both directions between the A
and B. and B and C terminals. There should be current
flow in onlv one direction.
A/C Switch
Test
NOTE: The Ay'C switch contains a diode. Use an analog
ohmmeter, or a digital ohmmeter equipped with a diode
tester.
Check for current flow in both directions between termi
nals 11 and 12. There should be current flow in only one
direction.

remove the field coil.
NOTE:
. Be careful not to damage the field coil
pressor during removal/installation.
. Once snap ring A is removed, replace
new one.
SNAP RING AReplace.

5. lnstall in the reverse order of removal, and:
install the field coil with the wire side facing
down (see above).
clean the pulley and compressor sliding surfaces
with non-petroleum solvent.
check the pulley bearings for excessive play.
make sure the snap rings are in the groove prop-
efly.
apply locking agent to the threads of the center
bolt, and tighten it securelY
make sure that the pulley turns smoothly after
it's reassembled.
1. Remove the relief valve and the O-ring.
NOTE:
. Do not let the compressor oil run out.
. Make sure there is no foreign matter in the sys-
tem.
RELIEF VALVE13.2 N.m {1.35 kgtm,9.76lbtftl
2. lnstall and tighten the relief valve.
Clean the mating surfaces.
Replace the O-ring with a new one at the relief
valve, and apply a thin coat of refrigerant oal
(ND-OIL 8: P/N 38899 - PR7 - A01) before install-
ing it.
NOTE:
. To avoid contamination, do not return the oil
to the container once dispensed, and never
mix it with other refrigerant oils.
. lmmediately after using the oil, replace the
cap on the container, and seal it to avoid
moisture absorption.
. Do not spill the refrigerant oil on the car; lt
may damage the painu if the refrigerant oil
contacts the paint, wash it off immediately.
Check for leaks, and insert the cap in the top of
the valve.

LOCKING TAB
a Some connectors have a clio on their side used to at-
tach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
a Some mounted connectors cannot be disconnected
unless you first release the lock and remove the con-
nector from its bracket.
