GENERATOR NO-LOAD PERFORMANCE
• Remove the left footrest mudguard. (

5-5)
• Disconnect the regulator/rectifier coupler

.
• Start the engine and keep it running at 2 800 r/min.
• Using the multi-circuit the voltage between W/R wire and
ground.
If the tester reads under the specified value, replace the genera-
tor coil with a new one.

 Generator no-load performance:
20 V and more at 2 800 r/min (When engine is cold)
REGULATOR/RECTIFIER
• Disconnect the regulator/rectifier coupler
1
.
• Remove the regulator/rectifier
2
.
Measure the voltage between the lead wire with the multi-circuit
tester as indicated in the table below. If the voltage is not within
the specified value, replace the regulator/rectifier with a new
one.

NOTE:
If the tester reads 1.4 V and below when the tester probes are
not connected, replace its battery.
