ELECTRICAL SYSTEM 8-9
GENERATOR COIL RESISTANCE
• Remove the fuel tank left side cover. (7-5)
• Disconnect the generator coupler.
Measure the resistance between the three lead wires.
If the resistance is not specified value, replace the stator coil
with a new one.
Also, check that the generator core is insulated.
09900-25008: Multi circuit tester set
Tester knob indication: Resistance (Ω)
Generator coil resistance: 0.5 – 1.5 Ω
(Yellow – Yellow)
∞ Ω (Yellow – Ground)
GENERATOR NO-LOAD PERFORMANCE
• Remove the fuel tank left side cover. (7-5)
• Disconnect the generator lead wire coupler.
• Shift the transmission to the neutral position.
• Start the engine and run it at 5 000 r/min.
Measure the AC voltage between the lead wires of the generator
using the multi circuit tester.
If the voltage is under the specified value, replace the AC gener-
ator with a new one.

Tester knob indication: Voltage (~)
Generator no-load performance (when engine is cold):
More than 60 V (AC) at 5 000 r/min
