Starting System
Starter Test lcont'dl
Ch€ck tor Wear and Damage
The starter should crank the engine smoothly and
steadily, lf the starter engages. but cranks the engine
erratically, remove it, and inspect the starter drive gear
and torque converter or flywheel ring gear for damage.
. Check the drive gear overrunning clutch for binding
or slipping when the armature is rotated with the
drive gear held,- lf damaged. replace the gears.
Check Cranking Voltsge and Curr€nt Draw
Cranking voltage should be no less than 8.5 volts.
Current draw should be no more than 350 amperes.
lf cranking voltage is too low, or current draw too high,
check for;
. dead or low batterv.
. open circuit in starter armature commutator seg-
ments,
. starter armature dragging.
. shorted armature winding.
o excessive drag in engine.
Check Cranking rpm
Engine speed during cranking should be above 100 rpm,
lf speed is too low, check for:
. loose battery or stanerterminals.
. excessively worn starter brushes,
. open circuit in commutator segments.
o dirty or damaged helical spline or drive gear.
. defective drive gear overrunning clutch.
Check Siarter Disengag€ment
With the shift lever in El or @ position (A/T) or with the
clutch pedal depressed (M/T), turn the ignition switch to
START (lll), and release to ON (ll).
The starter drive gear should disengage from the torque
converter or flywheel ring gear when you release the
Key.
lf the drive gear hangs up on the torque converter or fly-
wheel ring gear, check for:
. solenoid plunger and switch malfunction,
. dirty drive gear assembly or damaged overrunning
clutch.
Starter Solenoid Test
1. Check the hold-in coil for continuitv between the S
terminal and the armature housing (ground). The
coil is OK if there is continuitv,

4. Check tor mica depth. lf necessary, undercut mica
with a hacksaw blade to achieve proper depth. l{ ser-
vice limit cannot be maintained, replace the armature.

5. Check for continuity between the segments of the
commutator. lf an open circuit exists between any
segments, replace the armature.

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

-Performance Test
NOTE: Before staning the following checks. disconnect
the wire from terminal M. and make a connection as
described below using as heavy a wire as possible (prefer-
ably equivalent to the wire used for the car).
Pull-in CoilTest:
Connect the battery as shown, lf the staner pinion pops
out. it is working proPerly.
CAUTION: Do not leavo tho batterv connost€d for more
than 10 seconds.
Hold-in Coil Test:
Disconnect the battery from the M terminal' lf the pinion
does not retract, the hold-in coil is working properly.
CAUTION: Do not loavc lhe battsry connected for mot6
than 10 ssconds.
Retracting Tosi:
Disconnect the battery also from the body. lf the pinion
retracts immediately, it is working properly.
GAUTION: Do not loave the baftery conn€ctod tor more
than 10 seconds.
Startor No-load Tost:
Clamp the starter firmly in a vise.
Connect the starter to the battery as described in
the diagram below, and confirm that the motor
starts and keeps rotating.
