4. Measure the Rectifier Regulator output
peak voltage. If below specification, mea-
sure the stator coil output peak voltage.
Check the Rectifier Regulator if the out-
put peak voltage of the stator coil is
above specification.
NOTE:
Do not use the peak volt adapter when mea-
suring the output peak voltage of the Rectifier
Regulator.
