Regulated Voltage Inspection; Generator Inspection - Suzuki RMX450Z Service Manual

Regulated Voltage Inspection

Inspect the regulated voltage in the following
procedures:
1) Remove the seat. Refer to "Exterior Parts Removal
and Installation" in Section 9D (Page 9D-1).
2) Bring the tachometer close to the spark plug high-
tension cord.
3) Start the engine and keep it running at 5 000 r/min.
4) Measure the DC voltage between the (+) and (–)
battery terminals using the multi circuit tester. If the
voltage is not within the specified value, inspect the
generator and regulator/rectifier. Refer to "Generator
Inspection" (Page 1J-4) and "Regulator / Rectifier
Inspection" (Page 1J-8).
NOTE
When making this test, be sure that the
battery is fully charged condition.

2) Measure the resistance between the three lead
wires.
If the resistance is out of specified value, replace the
stator with a new one. Also, check that the generator
core is insulated properly.
NOTE
When making this test, it is not necessary to
remove the generator.

No-load Performance
1) Disconnect the generator lead wire coupler (1).
2) Bring the tachometer close to the spark plug high-
tension cord.
3) Start the engine and keep it running at 5 000 r/min.
