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.

RectifierTest
NOTE: The diodes are designed to allow current to pass
in one direction while blocking it in the opposite direc-
lion. Each diode must be tested for continuitv in both
directions with an ohmmeter that has diode checking
capability. Since the alternator rectifier is made up of
eight diodes (four pairs), there are a total of '16 checks,
1. Check for continuity in each ditection between the
B and P terminals, and between the E (ground) and
P terminals of each diode pair. All diodes should have
continuity in only one direction,
lf any of the eight diodes tails, replace the rectifier
assembly. (Diodes are not available separately.)
Gharging System
Alternator Brush Inspection
Remove the end cover, then lake oul the brush
holder by removing its two screws
Measure the length of the brushes with a vernier
calioer.
Aliornatol Brush Longlh:
Standard: 10.5 mm (O.41 in)
Servic. Limit: 1.5 mm (O.06 in)
lf the brushes are less than the service limit, replace
the b.ush holder assemblv.

Maintenance Reminder Unit Input Test
1.With the ignition switch OFF, disconnect the 5-P
connector from the reminder unit,
Inspect the connector and socket terminals to be
sufe they are all making good contact.
a lJ the terminals are bent, loose orcorroded, repair
them as necessary, and recheck the svstem.
a It the terminals look OK, make the following in-
Put tests at the connecto..- lf a test indicates a problem, tind and correct
the cause, then recheck the system.- It allthe input tests prove OK, the reminder unit
must be taulty; replace it.

Shift Lock Solenoid Test/Replacement
Remove the console, then disconnect the 2-p con-neclor oJ the shift lock solenoid from the main wireharness.
NOTE: Do not connect powe. to the B { - ) terminat(reverse polarity) or you will damsge the diode in-side the solenoid.
Connect battery power to the A terminal, ground theB terminal momentarily. and check solenoidoDeralron.
a lf the solenoid does not operate, replace it asdescribed in steps 3,4, and 5.a lJ the solenoid does operate, check and, if neces-sary, adiust its two positions as shown in step 5.

Test the motor by connecting battery power to the
A ( + ) terminal and ground to the B (- ) terminal.
a ll the motor does not run or fails to run smooth-

a lf the motor runs smoothly, but little or no wash-
er fluid is pumped. check for a disconnected orblocked washer hose, or a clogged pump outlet
in the motor.
