GENERATOR NO-LOAD PERFORMANCE
• Remove the front seat. (8-3)
• 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 gen-
erator with a new one.
 Generator no-load performance:
60 V and more at 5 000 r/min (When engine is cold)

 Tester knob indication: Voltage (~)
REGULATOR/RECTIFIER
• Disconnect the regulator/rectifier coupler 1 and remove the
regulator/rectifier 2.
• Measure the voltage between the lead wires using 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.
