START TEST
The air temperature must be between 59 and
100°F (15 and 38°C) before testing. |
Recommended procedure :
• |
Use a starter system
tester. |
• |
Connect and operate the equipment in
accordance with the manufacturer's
instructions. |
• |
Test and troubleshoot as
described. |
Alternate Procedure :
• |
Use the following equipment :
- Ammeter, 0~400A
- Voltmeter, 0~20V (accurate within 0.1
volt)
- Tachometer, 0~1,200
rpm |
After this test, or any subsequent repair,
reset the ECM/PCM to clear any
codes. |
Check the Starter
Engagement :
1. |
Remove the No.8(10A) fuse from the fuse/relay
box. |
2. |
Turn the ignition switch to START (III) with
the shift lever in "P" or " N" position (A/T) or with the clutch
pedal depressed (M/T). The starter should crank the
engine.
A. |
If the starter does not crank the
engine, go to step 3. |
B. |
If it cranks the engine erratically or
too slowly, go to "Check for Wear and Damage" on the next
page. | |
3. |
Check the battery, battery positive cable,
ground, starter cut relay, and the wire connections for looseness
and corrosion. Test again.
If the starter still does not crank the
engine, go to step 4. |
4. |
Unplug the connector from the
starter. |
5. |
Connect a jumper wire from the battery
positive (+) terminal to the solenoid terminal.
The starter should crank the
engine.

A. |
If the starter still does not crank the
engine, remove it, and diagnose its internal
problem. |
B. |
If the starter cranks the engine, go to
step 6. | |
6. |
Check the ignition
switch. |
7. |
Check the starter
relay. |
8. |
Check the A/T gear position switch (A/T) or
the clutch interlock switch (M/T). |
9. |
Check for an open in the wire between the
ignition switch and starter. |
If cranking voltage is
too low, or current draw too high, check for :
• |
open circuit in starter armature commutator
segments. |
• |
starter armature
dragging. |
• |
shorted armature
winding. |
• |
excessive drag in
engine. |
Check Cranking rpm
Engine speed during
cranking should be above 100 rpm.
If speed is too low,
check for :
• |
loose battery or starter
terminals. |
• |
excessively worn starter
brushes. |
• |
open circuit in commutator
segments. |
• |
dirty or damaged helical splines or drive
gear. |
• |
defective drive gear overrunning
clutch. |
Check starter disengagement
With the shift lever in
N or P position (A/T) or with the clutch pedal depressed (M/T), turn the
ignition switch to START(III), and release to ON(II).
The starter drive gear
should disengage from the flywheel or flywheel ring gear when you release
the key.
If the drive gear hangs
up on flywheel 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 continuity between
the S terminal and the armature housing (ground). The coil is OK if
there is continuity.

|
2. |
Check the pull-in coil for continuity between
the S and M terminals. The coil is OK if there is
continuity. |
FREE RUNNING TEST
1. |
Place the starter motor in a vise equipped
with soft jaws and connecta fully-charged 12-volt battery to starter
motor as follows : |
2. |
Connect a test ammeter (100-ampere scale) and
carbon pile rheostatas shown in the
illustration. |
3. |
Connect a voltmeter (15-volt scale) across the
starter motor. |
4. |
Rotate carbon pile to the off
position. |
5. |
Connect the battery cable from battery's
negative post to the startermotor
body. |
6. |
Adjust the carbon pile until battery voltage
shown on the voltmeter reads 11
volts. |
7. |
Confirm that the maximum amperage is within
the specifications and that the starter motor turns smoothly and
freely :
: Max. 90 Amps
: Min. 2,800 rpm
