GENERATOR COIL RESISTANCE
• Remove the engine sprocket outer cover.
• Disconnect the generator coupler.
Measure the resistance between the 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.

NOTE:
When making above test, it is not necessary to remove the gen-
erator.
GENERATOR NO-LOAD PERFORMANCE
• 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.

Generator no-load performance:
More than 60 V at 5 000 r/min (When engine is cold)
REGULATED VOLTAGE
• Remove the seat. (6-3)
• Remove the tray.
• Start the engine and keep it running at 5 000 r/min. with lighting
switch turned ON (except for E-24) and dimmer switch turned
HI position.
Measure the DC voltage between the + and - battery terminals
using the multi circuit tester. If the voltage is not within the speci-
fied value, inspect the generator and regulator/rectifier. (7-8
and 7-10)
NOTE:
When making this test, be sure that the battery is in fully-charged
condition.
