Checking the stator coil
1. Disconnect the stator coil coupler.
2. Connect the test harness (3 pins) to the
stator coil.
3. Measure the stator coil output peak volt-
age. Replace the stator coil assembly if
below specification.
Checking the Rectifier Regulator
1. Disconnect the Rectifier Regulator cou-
pler.
2. Connect the test harness (3 pins) to the
Rectifier Regulator.
3. Measure the Rectifier Regulator output
peak voltage. If below specification, mea-
sure the stator coil output peak voltage.
Replace the Rectifier Regulator if the out-
put peak voltage of the stator coil is
above specification.
