Five-step Troubleshooting
1. Verify The Complaint
Turn on all the components in the problem circuit to
verify the customer complaint. Note the symptoms.
Do not begin disassembly or testing until you have
narrowed down the Droblem area.
2. Analyze The Schomatic
Look up the schematic for the problem circuit. De-
termine how the circuit is supposed to work by trac-
ing the current paths from the power leed through
the circuit components to ground. It severalcircuits
fail at the same time, the luse or ground is a likely
cause.
Based on the symptoms and your understanding of
the circuit operation, identity one or more possible
causes of the Droblem.
3. lsolato The Problom By Testing The Circuit
Make circuit tests to check the diagnosis you made
in step 2. Keep in mind that a logical, simple proce-
dure is the key to etticient troubleshooting. Test for
the most likely cause of failure first. T.y to make
tests at points that are easilv accessible.
4. Fix The Problem
Once the specilic problem is identified, make therepair. Be sure to use proper tools and safeproceoures.
5. Mak6 Suro The Circuit Wolks
Turn on all components in the repaired circuit in allmodes to make sure you've fixed the entire problem.
It the problem was a blown Juse, be sure to test allof the circuits on thst tuse. Make sure no newproblems turn up and the original problem does not
recuf.

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
