REGULATED VOLTAGE
• Remove the seat. (
• Start the engine to keep it running at 2 800 r/min.
Measure the DC voltage between the + and - battery termi-
nals with the multi-circuit tester. If the voltage is not within the
standard range, inspect the generator and regulator/rectifier.
( 6-10)
NOTE:
When making this test, be sure that the battery is in
fully-charged condition.

GENERATOR COIL RESISTANCE
• Remove the left footrest mudguard. (
• Disconnect the generator coupler 1 .
• Measure the resistance between the W/R wire and ground
with the multi-circuit tester.
If the resistance is out of specified valve, replace the genera-
tor coil with a new one.

Tester knob indication: Resistance (W)
Generator coil resistance: 0.5 – 2.0 W (W/R – Ground)
NOTE:
When making above test, it is not necessary to remove the gen-
erator.
