Checking the Rectifier Regulator
1. Measure the Rectifier Regulator output
peak voltage. If below specification, mea-
sure the lighting coil output peak voltage.
Replace the Rectifier Regulator if the out-
put peak voltage of the lighting coil is
above specification.
WARNING
When checking the peak voltage do not
touch any of the connections of the digital
tester leads.
NOTE:
• Use the peak voltage adaptor with the digi-
tal circuit tester.
• When measuring the peak voltage, set the
selector on the digital circuit tester to the
DC voltage mode
.
NOTE:
After starting the engine, disconnect the out-
put lead (red lead) of the Rectifier Regulator
when measuring the output peak voltage.
