Starting System
Startel Test
NOTE: The air temDerature must be between 59 8nd
10OoF (15 and 38oC) before testing.
Recommendsd Procodure:
a Use a staner svstem tester.
a Connect and operate the equipment in accordance
with the manutacturer's instructions.
a Test and troubleshoot as described.
Altohato Procedure:
a Use the following equipment:- Ammeter. 0-4OO A- Voltmeter, O- 20 V {accurate within 0.1 volt)
- Tachometer, O- 120O rpm
a Hook up voltmeter and ammeter as shown'
NEGATIVE TERMINAL
NOTE: After this test, or any subsequent repair,
reset the ECM to clear any codes (see section 1 1)
23-76
2.
Chock Stan€r Engag6ment:
1. Disconnect the 2-P connector (ignition coil primary
lead) from the distributor.
Press the clutch pedal allthe way in (M/T), and turn
the ignition switch to "Start". The starter should
crank the engine.
NOTE: On cars equipped with manual transmission,
the engine will not crank unless the clutch pedal is
fully depressed.
lf the staner does not crank the engine go to step 3.
Check the baftery, battery positive cable, ground,
and the wire connections for looseness and cor-
rosion,
Test again. lf the starter still does not crank the en-
gine, go to step 4.
Bvpass the ignition switch citcuit as follows {make
sure the transmission is in neutral):
Unplug the connector (BLK/WHT wire and solenoid
terminsl) trom the starter. Then connect a jumper
wire from the battery positive ( + ) terminal to the
solenoid terminal. The starter should crank the
engrne.
a lf the starter still does not crank the engine,
replace it and diagnose its internal problems.
a lf the starter cranks the engine, go to step 5.
J.
4.

5. Check lor 8n op€n in the BLKMHT wire circuit be-
tween the staner and ignition switch, and con-
nectors.
6. Check the ignition switch (see page 23-70).
7, On cars with automatic transmission, check the A/Tgear position switch (neutral position switchl and
connector. On cars with manualtransmission, check
the staner cut relay, clutch interlock switch, and
connectors.
NOTE: Check the No. 39 (5O A) fuse in the under-hood
fuse/relay box for the starter cut relay.
Check tor Woar and Damago:
The starter should crank the engine smoothly and stead-
ily. lf th€ startsr engages, but cranks the engine errati-
cally, remove it. Inspect the starter, drive gear, and
flywheel ring gesr for damage.
a Check the drive gear overunning clutch for binding
or slipping when the armature is rotated with the drivegear held. Replace the gesrs if damaged.
Check Cranking Voltago 8nd Current Draw:
Cranking voltage should be no less than 8.O volts.
Current draw should be no more than 360 amperes.
lf cranking voltag€ is too low, or current draw too high,
check for:
a Fully charged battery
a Open circuit in starter armature commutatot segments
a Starter armature dragging
a Shoned armature winding
a Excessive drag in engine
Chack Cranking rpm:
Engine spsod during cranking should be above 1O0 rpm.
lf spe6d is too low, ch€ck for:
a Loose battsry or starter teminals
a Excessively worn starter brushes
a Open circuit in commutator segments
a Dirty or damaged helical spline or drive gear
a Defective drive gear overrunning clutch
Chock StErtor Disongagomoni:
Press the clutch pedal allth€ way in (M/T), turn the ioni-
tion switch to "lll" and rolease to "11".
The starter drive gear should disengage from the tlywheel
ring gear. When you rolease the key.
lf the drive gear hangs up on th€ flywheel ring gear, check
for:
a Solenoid plunger and switch malfunction
a Dirty drive gear assembly or damaged overrunning
clutch
