INSPECTION
Magnetic Switch Check

Before starting to check, disconnect the battery cable from the negative terminal.

Disconnect “M” terminal of starter motor.
1. Continuity test (between “S” terminal and switch body).

No continuity... Replace.
2. Continuity test (between “S” terminal and “M” terminal).

No continuity... Replace.
Pinion/Clutch Check
1. Inspect pinion teeth.

Replace pinion if teeth are worn or damaged. (Also check
condition of ring gear teeth.)
2. Inspect reduction gear teeth (If equipped).

Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.

If it locks or rotates in both directions, or unusual resistance is
evident... Replace.
Brush Check
BRUSH

Check wear of brush.
–Excessive wear... Replace.

BRUSH SPRING

Check brush spring tension with brush spring detached from
brush.
–Not within the specified values... Replace.
BRUSH HOLDER
1. Perform insulation test between brush holder (positive side) and
its base (negative side).
–Continuity exists... Replace.
2. Check brush to see if it moves smoothly.
–If brush holder is bent, replace it; if sliding surface is dirty, clean.
Yoke Check
Magnet is secured to yoke by bonding agent. Check magnet to see
that it is secured to yoke and for any cracks. Replace malfunctioning
parts as an assembly.
CAUTION:
Never clamp yoke in a vise or strike it with a hammer.
Armature Check
1. Continuity test (between two segments side by side).

No continuity... Replace.
2. Insulation test (between each commutator bar and shaft).

Continuity exists... Replace.Spring tension (with new brush) : Refer to SDS.

3. Check commutator surface.

Rough... Sand lightly with No. 500 - 600 emery paper.
4. Check diameter of commutator.

Less than specified value... Replace.
5. Check depth of insulating mold from commutator surface.

Less than 0.2 mm (0.008 in)... Undercut to 0.5 to 0.8 mm
(0.020 to 0.031 in)

ASSEMBLY
Apply high-temperature grease to lubricate the bearing, gears and frictional surface when assembling the
starter.
Carefully observe the following instructions.
Pinion Protrusion Length Adjustment
CLEARANCE (VQ23DE AND VQ35DE MODELS)

With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance “L” between the front
edge of the pinion and the pinion stopper.

Not in the specified value... Adjust by adjusting plate.
MOVEMENT (QR20DE MODELS)

Compare movement “L” in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by
hand until it touches stopper.

Not in the specified value... Adjust by adjusting plate.Clearance “L” : Refer to SDS. SC-38, "

CHARGING SYSTEMPFP:23100
System DescriptionBKS001MJ
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times:

through 10A fuse (No. 36, located in the fuse and fusible link block)

to alternator terminal 4 (“S” terminal).
“B” terminal supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 (“S” terminal) detecting the input voltage.
The charging circuit is protected by the 120A fusible link (letter A, located in the fusible link holder).
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied:

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 8 for the charge warning lamp.
Ground is supplied:

to combination meter terminal 22

through alternator terminal 3 (“L” terminal)

to alternator terminal “E”

through ground E2.
The charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine
running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate charge warning lamp, if any of the following symp-
toms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.

Trouble DiagnosisBKS001ML
Before performing an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspection
Table.

Before starting, inspect the fusible link.

Use fully charged battery.
WITH IC REGULATOR
NOTE:

If the inspection result is OK even though the charging system is malfunctioning, check the “B” terminal
connection (Check the tightening torque) and voltage drop.

Check condition of rotor coil, rotor slip ring, brush and stator coil. If necessary, replace malfunctioning
parts with new ones.
