ELECTRICAL SYSTEM 6-9
GENERATOR COIL RESISTANCE
• Remove the seat. (

5-3)
• Remove the fuel tank. (
!
4-2)
• Disconnect the generator coupler.
Measure the resistance between three lead wires.
If the resistance is not specified value, replace the stator with a
new one. Also, check that the generator core is insulated.

GENERATOR NO-LOAD PERFORMANCE
• Remove the seat. (

5-3)
• Remove the fuel tank. (
!
4-2)
• Disconnect the generator coupler.
• Start the engine and keep it running at 5 000 r/min.
Using the multi circuit tester, measure the voltage between three
lead wires.
If the tester reads under the specified value, replace the genera-
tor with a new one.
