7. 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.
8. With an ohmmeter, check 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,

NOTE:
. See section 11 when the malfunction indicator lamp(MlL) comes on.
. Perform an input test for the ignition control module(lCM) after finishing the fundamental tests for the
ignition system and the fuel and emissions systems.
. '97 -'98 models: The tachometer should operate nor-
mally if the ICM is OK.
L Remove the distributor ignition (Dl) cap, the distrib-
utor ignition (Dl) rotor, and the leak cover.

Using an ohmmeter, measure resistance between the
terminals. lf the resistance is not within sDecifications,
replace the ignition coil.
NOTE: Resistance will vary with the coil temperature;
specifications are at 68"F (20'C).
Plimary Winding Resistance
{Between the A and B terminals):

lgnition Wire Inspection and Test
1.Carefully remove the ignition wires by pulling on
the rubber boots. Do not bend the wires; you might
break them inside.
Check the condition of the ignition wire terminals. lf
any terminal is corroded, clean it, and if it is broken
or distorted, replace the ignition wire.
IGNITION WIRE
Connect the ohmmeter probes and measure resis-
tance.
lgnition Wire Resistance:
25 kO max. at 68'F 120'Cl

IRectifier Test
NOTE: The diodes are designed to allow current to pass
in one direction while blocking it in the opposite direc
tion. Since the alternator rectifier is made up of eight
diodes (four pairs), each diode must be tested for continuity in both directions with an ohmmeter that has diode
checking capability; a total of 16 checks.
'l. Check for continuity in each direction between- the B and P terminals.- E (ground) and P terminals.
All diodes should have continuity in only one direc-
tion.
2. lf any of the diodes fails, replace the rectifier assem-
bly. (Diodes are not available separatelv.)

Valve Seals
Replacement (cylinder head removal not required)
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA8845 with
YA8845-2A 7/8" auachment). Use approved eye protec-
tion.
1. Turn the crankshaft so that the No. 1 and the No. 4
pistons are at top dead center (TDC).
2. Remove the cylinder head cover.
3. Remove the distributor.
4. Loosen and disconnect the timing belt from the
camshaft pulleys.
5. Remove the camshaft holder bolts. then remove the
camshaft holders, the camshafts and rocker arms.

6. Using the 6 mm bolts supplied with the tool, mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit as shown.
7. Insert the cross shaft through the top hole of the
two uprights,
at.
9.
Select the 7/8 in. diameter long compressor attach-
ment, and fasten the attachment to the front hole of
the lever arm with the speed pin supplied.
Position the piston at TDC, and insen an air adaptor
into the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing the
springs and removing the valve keepers.
10. Put shop towels over the oil passages to prevent
the valve keepers from falling into the cylinder
head.
Position the lever arm under the cross shaft so the
lever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for the
spring being compressed. Use the rear position slot
on the lever as shown,
