Starter Circuit Troubleshooting
(cont'dl
6. Check the following items in the order listed untilyou find the open circuit.
. Check the BLIVWHT wire and connectors
between the under-dash fuse/relay box and theignition switch, and between the under-dash
fuse/relay box and the starter.. Check the ignition switch {see page 22-53).. Check the clutch interlock switch and connector.. Check the starter cut relay (see page 22-51).. Check LT GRN wire between the starter cut relayl
under-dash fuse/relay box and the clutch
interlock switch.. Check the BLK wire between the clutch interlock
switch and G501.
7, Check the cranking voltage and current draw.
ls ctanking voltage greatet than or equal to 8.7 V
and current draw less than or equal to 230 A?
YES-Go to step 8.
NO Replace the starter. or remove and
disassemble it, and check these items until you find
the cause.
. Starter armature dragging. Shorted armatu re winding. Excessive drag in engine
8. Check the engine speed while cranking the engine.
ls the engine speed above 100 tpm?
YES Go to step 9.
NO-Replace the starter, or remove and
disassemble it, and check for the following untilyou find the cause.
. Excessively worn starter brushes. Open circuit in commutator brushes. Open circuit in starter armature commutator
segments. Dirty or damaged helical splines or drive gear. Faulty drive gear clutch
9. Remove the starter, and inspect its drive gear andthe flywheel ring gear for damage. Replace anydamaged pans.I

Clutch Interlock Switch Test
1. Disconnect the clutch interlock switch 2P connector.
2. Remove the clutch interlock switch (A).
Check for continuity between the terminals
according to the table.
. lf the continuity is not as specified, replace the
clutch interlock switch.. lf OK, install clutch interlock switch and adjust
the pedal height (see page 12-4l..

1. Make sure you have the anti-theft code for the radio.
then write down the frequencies for the radio's
preset buttons.
2. Disconnect the negative cable from the battery first,
then disconnect the positive cable.
3. Disconnect the knock sensor connector.
4. Remove the bolt (A) securing the harness bracket,
then remove the intake manifold bracket (B).

Make sure the crimped side of the ring terminal (A)
is facing out.
Connect the positive cable and negative cable to
the batterY.
Start the engine to make sure the starter operates
propeny.
Enter the anti-theft code for the radio, then enter

Starter Overhaul (cont'dl
Planetary Gear Inspection
16. Check the planetary gears (A) and ring gear {B).Replace them if they are worn or damaged.
Overrunning Cluich Inspection
17. Slide the overrunning clutch along the shaft.
Replace it if it does not slide smoothly.
18. Rotate the overrunning clutch (A) both ways.
Does it lock in one direction and rotate smoothly inreverse? lf it does not lock in either direction or it
locks in both directions, replace it.
lf the starter drive gear (B) is worn or damaged,
replace the overrunning clutch assembly; the gear
is not available separately.
Check the condition of the flywheel ring gear.
Replace it if the starter drive gear teeth are
oamageo.

Starter Reassembly
20, Pry back each brush spring with a screwdriver, thenposition the brush about halfway out of its holder,
and release the spring to hold it there.
NOTE: To seatthe new brushes. slip a strip of #5OO
or # 600 sandpaper. with the grit side out, be&veen
the commutator and each brush, and smoothly
rotate the armature. The contact surface of the
brushes will be sanded to the same contour as the
commutator.
21lnstallthe armature in the housing, and installthe
brush holder. Next, pry back each brush spring
again, and push the brush down until it seats
against the commutator, then release the spring
against the end of the brush.
s
Install the starter end cover to retain the brush
holder.

l\-Alternator Replacement
1. Make sure you have the anti-theft code for the radio,
then write down the frequencies for the radio'spreset buttons,
2. Disconnect the negative cable from the battery first,
then disconnect the positive cable.
3. Remove the front bumper (see page 20-85).
4. Remove the right side headlight (see page 22-79).
5. Remove the reserve tank from the bracket.
6. Remove the drive belt (see page 4-26).
7. Remove the three bolts securing the alternator.
