Diagnostic Information and Procedures
Cranking System Symptom DiagnosisS7RS0B1904001
Possible symptoms due to starting system trouble would be as follows:
• Starting motor does not run (or runs slowly)
• Starting motor runs but fails to crank engine
• Abnormal noise is heard
Proper diagnosis must be made to determine exactly where the cause of each trouble lies in battery, wiring harness,
(including starting motor switch), starting motor or engine.
Do not remove motor just because starting motor does not run. Check the following items and narrow down scope of
possible causes.
1) Condition of trouble
2) Tightness of battery terminals (including ground cable connection on engine side) and starting motor terminals
3) Discharge of battery
4) Mounting of starting motor

Cranking System TestS7RS0B1904002
CAUTION!
Each test must be performed within 3 – 5
seconds to avoid coil from burning.

Pull-In Test
Connect battery to the magnetic switch as shown.
Check that plunger and pinion move outward.
If plunger and pinion don’t move, replace the magnetic
switch.
NOTE
Before testing, disconnect lead wire from
terminal “M” (2).

Hold-In Test
While connected as the figure with plunger out,
disconnect negative lead from terminal “M”.
Check that plunger and pinion remain out.
If plunger and pinion return inward, replace the magnetic
switch. Plunger and Pinion Return Test
Disconnect negative lead from starting motor body.
Check that plunger and pinion return inward.
If plunger and pinion don’t return, replace the magnetic
switch.
No-Load Performance Test
Connect battery and ammeter to starter as shown.
Check that starter rotates
smoothly and steadily with
pinion moving out. Check that ammeter indicates
specified current.
Specified current (No-load performance test)
90 A MAX. at 11 V

Repair Instructions
Starting Motor Dismounting and RemountingS7RS0B1906001
Dismounting1) Disconnect negative (–) battery lead at battery.
2) Disconnect magnetic switch lead wire (1) and battery cable (2) from starting motor terminals.
3) Detach shift & select control cable bracket from transaxle. (M/T model only)
4) Remove starting motor mount bolt (3) and nut (4).
5) Remove starting motor (5).
Remounting
Reverse the dismounting procedure noting the following.
• Tighten battery cable nut (6) to specified torque.

Starting Motor InspectionS7RS0B1906003
Plunger
Inspect plunger for wear. Replace if necessary.
Magnetic Switch
Push in plunger and release it. The plunger should
return quickly to its original position. Replace if
necessary.
Pull-in coil open circuit test
Check for continuity across magnetic switch “S” terminal
(1) and “M” terminal (2). If no continuity, coil is open and
should be replaced. Hold-in coil open circuit test
Check for continuity across ma
gnetic switch “S” terminal
(1) and coil case. If no continuity, coil is open and should
be replaced.
Rear Bracket Bush
Inspect bush for wear or damage. Replace if necessary.
Brush
• Check brushes for wear. Measure length of brushes and if below the limit,
replace the brush.
Brush length
Standard: 12.3 mm (0.48 in.)
Limit: 7.0 mm (0.28 in.)
• Install brushes to each brush holder and check for smooth movement.

Charging System Circuit
The generator features solid state regulator that it mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brus h holder assembly is attached to the rear housing. The
regulator voltage is being controlled by ECM under some cond itions while driving. Refer to “Generator Control System
Description in Section 1A”.
The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication.
Two brushes carry current through the two slip rings to the field coil mounted on the rotor, and under normal conditions
will provide long period of attention-free service.
The stator windings are assembled inside a laminate d core that forms part of the generator frame.
A rectifier bridge connected to the stator windings contains diodes, and electrically changes the stator AC. voltages to
a D.C. voltage which appears at the generator output terminal.
