Generator Removal And Installation - Suzuki GSX-R750 Service Manual

1J-4 Charging System:
3) Measure the resistance between the three lead
wires.
If the resistance is out of specified value, replace the
stator with a new one. Also, check that the generator
core is insulated properly.
NOTE
When making this test, be sure that the
battery is in fully charged condition.

4) Using the multi-circuit tester, measure the voltage
between three lead wires.
If the tester reads under the specified value, replace
the generator with a new one.
