9-10 ELECTRICAL SYSTEM
REGULATED VOLTAGE
• Remove the seat. (8-3)
• Start the engine and keep it running at 5 000 r/min. with light-
ing switch turned ON and 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/rectifier.
(9-10 and -11)
NOTE:
When making this test, be sure that the battery is in
fully-charged condition.
 Regulated voltage (Charging output):
 09900-25008: Multi circuit tester set
 Tester knob indication: Voltage ()
GENERATOR COIL RESISTANCE
• Remove the tool box. (8-41)
• 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 insulated prop-
erly.
 Generator coil resistance: 0.2 – 1.5 Ω (Yellow – Yellow)
 09900-25008: Multi circuit tester set
 Tester knob indication: Resistance (Ω)
NOTE:
When making above test, it is not necessary to remove the gen-
erator.
13.5 – 15.0 V at 5 000 r/min
