Generator InspectionS6RW0D1A06005
Rotor
1) Using ohmmeter, connect positive terminal to “FR” terminal and connect negative terminal to “B” terminal of
generator, check that continuity between “B” terminal and “FR” terminal. If there is no continuity, replace rotor or
regulator.
2) Using an ohmmeter, check for continuity between
slip rings of rotor. If there is no continuity, replace the
rotor.
Standard resistance between slip rings of rotor
2.7 – 3.1 Ω at 20 °C (68 °F)3) Using an ohmmeter, check that there is no continuity
between slip ring and rotor. If there is continuity,
replace the rotor.

4) Check slip rings for roughness or scoring. If rough or
scored, replace the rotor.
Using a vernier caliper, measure the slip ring
diameter. If the diameter is less than minimum,
replace the rotor.
Slip ring diameter
Standard: 14.2 – 14.4 mm (0.560 – 0.566 in.)
Limit: 12.8 mm (0.503 in.)
Stator
1) Using an ohmmeter, check all leads for continuity. If
there is no continuity, replace the stator.
2) Using an ohmmeter, check that there is no continuity
between coil leads and stator core. If there is
continuity, replace the stator.
Brush and Brush Holder
Check each brush for wear by measuring its length as
shown. If the brush is found worn down to service limit,
replace the brush.
Exposed brush length “a”
Standard: 10.5 mm (0.41 in.)
Limit: 1.5 mm (0.05 in.)Rectifier
1) Using an ohmmeter, connect one tester probe to the
“B” terminal (1) and the other to each rectifier
terminal (2).
2) Reverse the polarity of the tester probes and repeat
Step 1).
3) Check that one shows continuity and the other
shows no continuity.
If there is continuity, replace the rectifier.
4) Using an ohmmeter, connect one tester probe to
each negative terminal (1) and the other to each
rectifier terminal (2).
5) Reverse the polarity of the tester probes and repeat
Step 4).
6) Check that one shows continuity and the other
shows no continuity.
If there is continuity, replace the rectifier.

Exhaust System
General Description
Exhaust System DescriptionS6RW0D1B01001
The exhaust system consists of an exhaust manifold, three-way catalytic converter (TWC) in catalyst case, exhaust
pipes, a muffler and seals, gasket and etc.
The three-way catalytic converter is an emission control device added to the exhaust system to lower the levels of
Hydrocarbon (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.
Diagnostic Information and Procedures
Exhaust System CheckS6RW0D1B04001
WARNING!
To avoid the danger of being burned, do not touch the exhaust system when the system is hot. Any
service on the exhaust system should be performed when the system is cool.

At every interval of periodic maintenance service, and when vehicle is raised for other service, check exhaust system
as follows:
• Check rubber mountings for damage, deterioration, and out of position.
• Check exhaust system for leakage, loose connection, dent and damage.
• If bolts or nuts are loosened, tighten them to specified torque referring to “Exhaust System Components”.
• Check nearby body areas damaged, missing, or mispositioned part, open seam, hole connection or any other
defect which could permit exhaust fumes to seep into vehicle.
• Make sure that exhaust system components have enough clearance from underbody to avoid overheating and
possible damage to vehicle underbody.
• Any defect should be fixed at once.
