ELECTRICAL SYSTEM 8-9
GENERATOR COIL RESISTANCE
• Remove the fuel tank 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.

GENERATOR NO-LOAD PERFORMANCE
• Remove the fuel tank cover. (!7-5)
• Disconnect the generator lead wire coupler.
• 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.

& Generator no-load performance (when engine is cold):
More than 60 V (AC) at 5 000 r/min
