JArmature Inspection and Test
1.Inspect the armature for wear or damage due to con-
tact with the permanent magnet or field winding.
. lf there is wear or damage. replace the armature.
Inspect for damage.
2. Check commutator surface and diameter.
. lf the surface is dirty or burnt. resurface with emery
cloth or a lathe within the following specifications,
or recondition with #500 or #600 sandpaper.
. lf commutator diameter is below the service limit,
replace the armature.

3. Measure the commutator runout.
. lf the commutator runout is within the service
limit, check the commutator for carbon dust or
brass chips betlveen the segments.
. lf the commutator runout is not within the ser-
vice limit, replace the armature.

6. Place the armature on an armature tester. Hold a
hacksaw blade on the armature core.

. lf the blade is attracted to the core or vibrates
while the core is turned, the armature is shorted.
Replace the armature.
7. Check with an ohmmeter that no continuity exists
between the commutator and armature coil core,
and between the commutator and armature shaft. lf
there is continuity, replace the armature.

1. Check that there is no continuity between the O and
o brush holders.
lf there is continuity, replace the brush holder
assemoly.

2. Insert the brush into the brush holder, and b.ing the
brush into contact with the commutator, then attach
a spring scale to the spring. Measure the spring ten-
sion at the moment the spring lifts off the brush.

Brush Inspection
Measure the brush length. lf not within the service limit,
replace the brush (or brush holder assembly).
Brush Length
NOTE: To seat new brushes after installing them in their
holders, slip a strip ot #500 or #600 sandpaper. with the
grit side up, over the commutator and smoothly rotate
the armature. The contact surface of the brushes will be
sanded to the same contour as the commutator.
Overrunning Clutch lnspection
Slide the overrunning clutch along the shaft. Does it
move freely? lf not, replace it.
Rotate the overrunning clutch both ways. Does it
lock in one direction and rotate smoothly in
reverse? lf it does not lock in either direction or it
locks in both directions, replace it.

-lgnition Timing Inspection and Setting
1.Check the idle speed, and adjust it it necessary (see
section 'l '1 ).
Pull out the service check connector 2P (BRN and BLK
wires) from the connector holder located under the
dash on the front passenger side, then connect the
SCS service connector (T/N 07PAZ - 0010'100) to it.
Start the engine. Hold the engine at 3.000 rpm with
no load {A,/T in E or E. M/T in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. 1 ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights. blower fan, rear window defogger, and
air conditioner are not operating.

Loosen the distributor mounting bolts. and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing, or clockwise to retard the tim-
ing.

Tighten the distributor mounting bolts, and recheck
the ignition timing.
Disconnect the SCS service connector from the ser-
vice check connector.

JRotor Slip Ring Test
1. Check the resistance betlveen the slip rings
There should be 1 8 - 3 0 ohms
. lf resistance meets the specification, go to step 2.
. lf resistance does not meet the specification,
reolace the alternator'
SLIP BINGS
2. Check that there is no continuity between the slip
rings and the rotor or rotor shaft.
3. lf the rotor fails either continuity check, replace the
alternator.
Stator Test
'1. Check that there is continuity between each pair of
leads.
CORE
Check that there is no continuity between each lead
and the coil core.
lf the coil fails either continuity check, replace the
alternator.
