7-10 ELECTRICAL SYSTEM
STATOR COIL RESISTANCE
Remove the left frame cover. (
Disconnect the stator coil lead wire coupler.
Measure the resistance between the three lead wires using the
multi circuit tester. If the resistance is not within the specified
value, replace the stator coil with a new one.
Also, check that the generator core is insulated.

Tester knob indication: Resistance (Ω Ω Ω Ω Ω )
Stator coil resistance
Standard: 0.50 – 1.25 Ω Ω Ω Ω Ω (Yellow – Yellow)
AC GENERATOR NO-LOAD PERFORMANCE
Remove the left frame cover. (
Disconnect the stator coil lead wire coupler.
Start the engine and run it at 5 000 r/min.
Measure the AC voltage between the lead wires of the genera-
tor using the multi circuit tester. If the voltage is under the speci-
fied value, replace the AC generator with a new one.

AC generator no-load performance
Standard:
More than 75 V (AC) at 5 000 r/min
