9-10 ELECTRICAL SYSTEM
REGULATED VOLTAGE
• Remove the front seat. (8-7)
• Start the engine and keep it running at 5 000 r/min with the
dimmer switch turned HI position.
• Measure the DC voltage between the + and - battery termi-
nals using the multi-circuit tester. If the voltage is not within
the specified value, inspect the generator and regulator/recti-
fier. (9-10 and -11)
NOTE:
When making this test, be sure that the battery is in fully-charged
condition.
09900-25008: Multi-circuit tester set
Tester knob indication: Voltage ()
Regulated voltage (Charging output):
14.0 – 15.5 V at 5 000 r/min
GENERATOR COIL RESISTANCE
• Lift and support the fuel tank. (5-3)
• Disconnect the generator coupler.
• 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 insu-
lated properly.

NOTE:
When making above test, it is not necessary to remove the gen-
erator.
