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.

Starting System
Clutch Interlock Switch Test
1 . Remove the dashboard lower cover and knee bolster
(see page 23-70), then disconnect the 2-P connec-
tor from the switch.
2. Check tor continuity between the terminals accord-
ing to the table.
lf necessary. replace the switch or adjust the switch
oosition (see section 12).
Starter Solenoid Test
1. Check for continuitv between the tetminals accotd-
ing to the table.

Armature Inspection and Test
1 . Inspect the armature for wear or damage due to con-
tact with the field coil magnets.
Inspect tor damage
A dirtv or burnt commutator surface may be l€sul-
faced with emery cloth or a lathe within the follow-
ing specilications.

lf the commutator runout and diamete. are within
limits, check the commutator tor damage or for car-
bon dust or brass chips between the segments.
lf the surf6c6 is dirty, recondition it with # 50O or
# 600 sandpsper.
