Checking the lighting coil
1. Measure the lighting coil output peak
voltage. Replace the stator coil if below
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
.
